The Moneytree Link SDK is a toolbox you can use to integrate with Moneytree's services.
The SDK provides ways to authenticate, store tokens, and launch Moneytree Web Services. It also provides a plugin for LINK Kit, a fully integrated web PFM solution.
ℹ️ All code samples provided here are examples for your convenience.
- Moneytree LINK SDK (Android)
We provide a sample application for you to test out the various SDK components and see how the SDK is integrated into a client app. If you would like to try out the sample application, clone or download the contents of this repository and open it in Android Studio. See additional information about configuring the sample app in AwesomeApp Example Setup.
The SDK components are distributed via Maven. See Getting the SDK for how to configure your dependencies in your gradle
files.
The Moneytree LINK SDK is comprised of a Core SDK and the Moneytree LINK Kit module.
The Core SDK is the tool offering you connectivity to our services, plus some state handling for tokens.
The Moneytree LINK Kit provides you with a web based UI version of our PFM services and is there to simplify the integration process.
ℹ️ Moneytree LINK Kit is the name of the refreshed and re-branded version of Issho Tsucho.
⚠️ The SDK requires Android 6 and above. YourminSdkVersion
must be set to at least23
.
The Moneytree LINK SDK is offered through Maven Central. Add the following dependencies in your build.gradle
or build.gradle.kts
file:
dependencies {
// Moneytree LINK SDK
implementation("app.moneytree.link:core:6.x.x")
}
Optionally, if you have contracted LINK Kit:
dependencies {
// Moneytree LINK SDK
implementation("app.moneytree.link:core:6.x.x")
// LINK Kit too.
implementation("app.moneytree.link:link-kit:6.x.x")
}
❗ All libraries are subjected to certain contracts with Moneytree. Moneytree servers will reject any SDK request that does not have a valid and active contract.
The SDK works by receiving callbacks from our web services through custom schemes. The required Android Manifest entries have already been setup and will be merged by the Manifest Merger. They are using Android Manifest Variables, so to receive the callbacks you need to add the following to your app's build.gradle
file.
android {
defaultConfig {
manifestPlaceholders += [
// For production remove `-staging` from below
"linkHost": "myaccount-staging.getmoneytree.com",
// clientIdShort: "<first 5 chars of your client ID>"
"clientIdShort": "xxxxx"
]
}
}
Replacing xxxxx
above with the first 5 characters of your Client ID.
For example; if your Client ID is abcde1234567890moneytree
, your clientIdShort
would be abcde
.
ℹ️ The Client ID will be provided by Moneytree once you have an active contract. Please contact us for more information or further questions.
Of course, you can choose any ways to define the values above as you like.
If you choose to implement the optional Passwordless Sign Up and Login features, you need to add the following intent filter to an activity of your choice:
⚠️ Do not override any Moneytree LINK SDK activities. This should be added to the activity in your application used to manage the Moneytree LINK SDK.
⚠️ If you are targeting Android 12 (API v31) and above, you will also need to includeandroid:autoVerify=true
as a property in your intent filter. Web intent resolution in Android 12
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="${linkHost}"
android:pathPrefix="/link/${clientIdShort}"
android:scheme="https" />
</intent-filter>
You will finally need to add the INTERNET
permission if you do not have it already.
<uses-permission android:name="android.permission.INTERNET" />
ℹ️ Complete configuration by contacting Moneytree with the information in Passwordless Sign Up/Login and Login Link
As of Android 12, for LINK Kit to integrate with your application as a trusted web activity that does not show browser UI, we must register your application in a digital asset links file hosted by Moneytree. In order to do so, we need your application ID (which looks something like com.companyname.appname
) and your SHA-256 app signing fingerprints.
In this step you first need to choose an authorization type for your application. Ask our representatives if you are unclear as to which one meets your needs.
The supported authorization flows are:
Module | Authorization flow | Notes |
---|---|---|
Core | PKCE; Saves the user access token on device | |
Core | Authorization Code Grant Type (Deprecated); Saves the user access token in your external server | Since v4.0.0 |
LINK Kit | PKCE; Saves a token locally on device | Using this module forces the PKCE flow as its purpose is to keep the implementation simple |
The entry point of the SDK is the MoneytreeLink
class which contains all the public interfaces.
To initialize it call its init(context, configuration)
method. The configuration
parameter is of type MoneytreeLinkConfiguration
. Use its builder to provide the SDK with its configuration:
// Application class
override fun onCreate() {
super.onCreate()
val configuration = MoneytreeLinkConfiguration.Builder()
.linkEnvironment(LinkEnvironment.Staging) // .Staging or .Production
.clientId("1234567890abcde...") // your ClientId
.scopes(MoneyTreeLinkClient.GuestRead, ...) // scope(s)
.authenticationMethod(AuthenticationMethod.Credentials) // Moneytree login page flow
.build();
MoneytreeLink.init(this, configuration)
}
The scopes(...)
function used in the Builder
above is basically a set of permissions the user needs to provide to the accessing application to be able to get a user token. More on this in Account OAuth Access Scopes (User Access Permissions).
authenticationMethod
gives you control over the kind of authentication flow you want to use before authorization. You can find more in Choosing your Authentication method.
ℹ️ As the SDK configuration is mostly unique and will most likely be used throughout your app we strongly recommend to do all initialization inside your
Application
class.
⚠️ Support for Authorization Code Grant has been deprecated and will be removed in future releasesAuthorization Code Grant without PKCE creates important security concerns when used on mobile applications. The flow offers no way to identify he requesting application allowing for potential interception of it.
Authorization code grant is a type of auth flow that delegates the user access token exchange process to your server. That way you gain more control over the token's location, however, with some drawbacks.
The SDK functionality is limited when using an authorization code as it does not have the access token required. For instance the getToken()
method cannot function and will throw an error, or the SDK cannot be used to register the user's FCM token. Another drawback is the addition of networking steps in the process as your app now has to communicate with your server to register/unregister access tokens based on user activity.
The SDK initialization is basically the same as in the PKCE flow, with a small difference on the initialization of the MoneytreeLinkConfiguration
class:
val conf = MoneytreeLinkConfiguration.Builder()
.linkEnvironment(LinkEnvironment.Staging)
.clientId("1234567890abcde...")
.scopes(MoneyTreeLinkClient.GuestRead, ...)
// Set redirectUri to your server endpoint to receive an auth code
.redirectUri("https://your.server.com/token-exchange-endpoint")
.build()
We add a call to redirectUri(uri)
that takes the string URI of the endpoint connection for token processing.
⚠️ The following methods will not work ifAuthorization Code Grant
is the selected auth flow.
- getToken
- registerRemoteToken
- unregisterRemoteToken
The authentication method determines which Moneytree authentication page will appear. We provide three (3) authentication methods:
- Credentials: You will see the usual page where you can sign up or log in using your email and password.
- Passwordless: For log-in, the user needs to enter their email address where they will receive their authentication link. For sign-up the flow is executed by calling
onboard()
(see Configuring Passwordless Sign Up/Login & Login Link). - Single Sign On (SSO): When configured, your users will authenticate to Moneytree via the Identity Provider (IdP) that you have specified.
⚠️ SSO requires configuration of the Identity Provider (IdP) you want to use, so that our system can connect to it. If you want to use SSO please contact our customer success team and they will work with you to get the needed configuration done.
The authentication method selection can be done through the MoneytreeLinkConfiguration
when initializing the SDK (or LINK Kit).
MoneytreeLinkConfiguration.create(
linkEnvironment = LinkEnvironment.Staging,
clientId = "[myClientId]",
scopes = setOf(
MoneytreeLinkScope.GuestRead,
MoneytreeLinkScope.AccountsRead,
MoneytreeLinkScope.TransactionsRead
),
// You options are:
// AuthenticationMethod.Credentials
// AuthenticationMethod.Passwordless
// AuthenticationMethod.SingleSignOn
authenticationMethod = AuthenticationMethod.Credentials
)
The same flow with the Java style builder:
MoneytreeLinkConfiguration.Builder()
.linkEnvironment(LinkEnvironment.Staging)
.clientId("[myClientId]")
.scopes(
MoneytreeLinkScope.GuestRead,
MoneytreeLinkScope.AccountsRead,
MoneytreeLinkScope.TransactionsRead
)
// You options are:
// AuthenticationMethod.Credentials
// AuthenticationMethod.Passwordless
// AuthenticationMethod.SingleSignOn
.authenticationMethod(AuthenticationMethod.Credentials)
.build()
ℹ️ As this is global SDK configuration the selection you make will take effect over all flows that have the potential to lead to an authentication flow. Those flows are:
- Authorization
- Opening the Moneytree Vault
- Opening the Moneytree Settings
- Starting LINK Kit
LINK Kit, the re-brand and refresh of Issho Tsucho, is a fully integrated web PFM (Personal Financial Management) module offered with the purpose of simplifying the presentation of the data we offer.
⚠️ To use LINK Kit you need to have a contract and in extension a Client ID that supports it.
To initialize the module you first need a MoneytreeLinkConfiguration
, similar to the PKCE flow.
Then call the LinkKit
's init(context, configuration)
:
// Application class
override fun onCreate() {
super.onCreate()
val configuration = MoneytreeLinkConfiguration.Builder()...
// Initializing LINK Kit
LinkKit.init(this, configuration)
}
You will notice that you do not need to call MoneytreeLink.init(...)
. LINK Kit will take care of initializing the Core SDK for you. In case that you need to access it call the following:
val linkClient = LinkKit.linkClient();
As seen in the previous sections, a set of scopes must be defined at initialization for the SDK to function. These are effectively data access level permissions that the host app requests from the user's account. What you can do with the access provided depends on the scopes defined.
The Link SDK is defining the following scopes in the MoneytreeLinkScope
enum:
Scope | Provided permission |
---|---|
GuestRead | Access to basic account information. |
AccountsRead | Access to read personal account balances and information. |
TransactionsRead | Access to read personal account transactions. |
TransactionsWrite | Access to write personal account transactions. |
CategoriesRead | Access to read transaction categories. |
InvestmentAccountsRead | Access to read investment account balances and information. |
InvestmentTransactionsRead | Access to read investment account transactions. |
RequestRefresh | Allows your application to manually request Moneytree to retrieve up-to-date user data from financial institutions. |
PointsRead | Access to read point account information. |
PointTransactionsRead | Access to read point account transactions. |
NotificationsRead | Access to read notification information. |
For the base functionality of the SDK (Vault, Login/out, Customer support) we recommend to at least ask for the following 3 scopes:
- GuestRead
- AccountsRead
- TransactionsRead
LINK Kit has strict requirements and is always requesting the following scopes:
- GuestRead
- AccountsRead
- TransactionsRead
- TransactionsWrite
- PointsRead
- InvestmentAccountsRead
- InvestmentTransactionsRead
- RequestRefresh
Contact our representative if you have questions about scopes.
The first step to using the SDK is to authorize it, have a valid login/register for an account and consequently a token.
You can authorize by calling authorize(activity, options)
on the MoneytreeLink
singleton. The config
parameter is of type LinkAuthOptions.Authorize
.
You can use LinkAuthOptions.create {}
(LinkAuthOptions.Companion.create in Java) extension function or the LinkAuthOptions.builder()
to setup your authorization request.
PKCE flow:
// Create your options first
val authConfig = LinkAuthOptions
.create {
authFlow = LinkAuthFlow.Pkce.create()
}
.buildAuthorize(email = "[email protected]")
// Start authorization process
MoneytreeLink.getInstance().authorize(activity, authConfig)
Authorization Code flow (deprecated):
Similar to PKCE flow above. The main difference is that the LinkAuthOptions.CodeGrant(String)
requires a state string for the OAuth process. This state needs to be unique per request. For more information refer to the OAuth guidelines.
// Create options
val authConfig = LinkAuthOptions
.create {
authFlow = LinkAuthFlow.CodeGrant("random-state-string") // Provide the OAuth Authorization Code flow state
}
.buildAuthorize(email = "[email protected]")
// Authorize
MoneytreeLink.getInstance().authorize(activity, authConfig)
ℹ️ Full
LinkAuthOptions
builder options:LinkAuthOptions.builder() .presentSignUp(Boolean) // Boolean on whether to show login or register on the web .auth(LinkAuthFlow) // `Pkce.create()` or `CodeGrant("state")`. Choose your poison... .forceLogout(Boolean) // Will force the login flow again // Used for flows that go through the `MoneytreeLink.getInstance().authorize(...)` call. // Takes the user's email. This is optional and can be used to pre-populate the email fields // in the web form. .buildAuthorize(String) // Used for flows that go through the `MoneytreeLink.getInstance().onboard(...)` call (more on this in the next section). // Takes the user's email. This is required as the process creates the account with this email // and sends a confirmation email. .buildOnboarding(String)
⚠️ Theauthorize()
flow has some combinations that force specific flows. Specifically:
- When
presentSignup = true
andauthenticationMethod
isPasswordless
thenauthenticationMethod
is disregarded and you will still get the credentials screen. Passwordless Sign-up is handled by theonboard()
entry point.- When
authenticationMethod
is set to SSO thenauthorize
flows disregardpresentSignup
as there is no concept of Signup or Login in the SSO method.
LINK Kit flow:
LINK Kit enforces a PKCE flow behind the scenes as it needs to have the user token available to start properly scoped.
To start LINK Kit use:
LinkKit.getInstance().launch(
activity = activity,
authenticationMethod = AuthenticationMethod.Credentials,
object : LinkKit.LinkKitListener {
override fun onLaunched() {
// callback
}
override fun onError(exception: MoneytreeLinkException?) {
// callback
}
}
)
LinkKit.LinkKitListener
is not required if you do not need to get callbacks.
⚠️ For more on the usage ofauthenticationMethod = AuthenticationMethod.Credentials
in the code block above refer to Choosing your Authentication Method
Passwordless Sign Up/Login and Login Link are new, secure, passwordless, email-based registration and login features offered from v6 in order to allow your customers easier access to Moneytree services. These features are email based. When Passwordless Sign Up/Login is requested, the user will receive a one-time url capable of creating an account. When Login Link is requested, the user will receive a one-time url that can log them in or navigate to their account settings.
⚠️ Please make sure to complete Configuring Passwordless Sign Up/Login & Login Link steps first.
You must inform Moneytree's customer success team if you want to support either or both Passwordless Sign Up/Login and Login Link. When doing so, please provide your client ID, the bundle ID of your iOS app and the SHA-256 fingerprint certificate of your Android app, as well as whether it is for the test environment, production, or both.
Your SHA-256 fingerprint certificate is necessary because Login Link uses Android App Links for extra security. It verifies the connection between your app and the link received and send the intent directly to your app without showing the system's app selection sheet. To that effect you will need to provide us with your production key's fingerprint for your released app. If you want to be able to confirm this functionality on your debug artifact as well you will have to create a static debug signing key and provide its fingerprint too. You can learn more on App Links here.
Once Moneytree completes the configuration of your app, your users will see the new registration and login screens. Note that these screens still provide the option to register or log in with a password if they prefer.
⚠️ Passwordless Sign Up/Login requires further configuration and implementation. Specifically for signup, a different SDK API call is being used.That makes it incompatible with the spirit of direct access of LINK Kit. However, if you want to use it with LINK Kit you can implement the required authorization flows manually and then call LINK Kit, to open it on top of the finished authorization.
To use it call onboard(Activity, LinkAuthOptions.Onboarding)
, where:
activity
is theActivity
in the context of which the onboarding request is created.options
of typeLinkAuthOptions.Onboarding
. Constructed by callingLinkAuthOptions.create {}
(LinkAuthOptions.Companion.create in Java) extension function or theLinkAuthOptions.builder()
, it holds all the information required to go through any authorization flow.
val authConfig = LinkAuthOptions
.create {
authFlow = LinkAuthFlow.Pkce.create()
}
.buildOnboarding(email = "[email protected]") // Email is required for Onboarding
// Launch the onboarding process
MoneytreeLink.getInstance().onboard(activity, options)
It has two main uses. Login and navigation.
Login can be done through any of the normal auth flows. The user will be given the option to login through email link (login link) or using email and password.
For requesting a Login Link navigation use requestLoginLink(String, String, Action)
, where the parameters are:
email
: the user's email used to locate the user requesting the link.destination
: the path that will be used to navigate to the requested account pagelistener
: of typeAction.OnCompletionListener
, tells us if requesting the login link has succeeded or not.
ℹ️ The destinations currently supported by login links are:
MoneytreeLink.ML_DESTINATION_SETTINGS
, navigating to the settings page of the user's account.MoneytreeLink.ML_DESTINATION_LANGUAGE
, navigating to the language selection page of the user's account settings.MoneytreeLink.ML_DESTINATION_AUTHORIZED_APPS
, navigating to the authorized applications page of the user's account settings.MoneytreeLink.ML_DESTINATION_DELETE_ACCOUNT
, navigating to the account deletion page of the user's account settings.MoneytreeLink.ML_DESTINATION_EMAIL_PREFERENCES
, navigating to the email preferences page of the user's account settings.MoneytreeLink.ML_DESTINATION_UPDATE_EMAIL
, navigating to the email update page of the user's account settings.MoneytreeLink.ML_DESTINATION_UPDATE_PASSWORD
, navigating to the password update page of the user's account settings.
After you request a Login Link flow you need to consume the incoming deep link.
To do so, you need to capture the URI from the email using an Intent Filter and then provide it to the SDK using consumeLoginLink(AppCompatActivity, Uri, Action)
.
When you receive the intent in your activity call consumeLoginLink(AppCompatActivity, Uri, Action)
intent.data?.also { uri ->
MoneytreeLink.getInstance().consumeLoginLink(Activity, Uri)
}
The parameters are:
activity
: is the context used to open the in app browser and setup aLinkResultListener
if thelistener
parameter is set.uri
: the Uri you receive fromintent.getData()
when the app captures the link from the received email.listener
: optional (overloaded), automatically adds, and removes when not needed, anAction
listener to the centralized lifecycle capable callback system. This is more of a convenience tool rather than a necessity as you can still subscribe to the events of the system as explained in SDK callback flow
You might need to logout your user from the Moneytree services or clear the tokens the SDK is holding. For that we provide the following functions:
deleteCredentials()
clears the saved Token from the encrypted storage.logout(activity)
takes the activity instance and launches an in-app browser flow calling our services to logout and clear all browser sessions. CallsdeleteCredentials()
internally.
⚠️ Please have in mind thatdeleteCredentials()
does not clear the user's logged in state from the browser session. It simply deletes the access token the SDK holds. If you try to authorize again and the browser session has not expired you will not go through the login page. A new Token will be provided for the SDK to store.
To open the Vault the SDK interface provides the openVault(Activity, LinkRequestContext)
function, where:
activity
is the context used to start the web navigation process.requestContext
is created usingLinkRequestContext.Builder
and holds all the required information for opening the vault and navigating to the requested page.
MoneytreeLink.getInstance().openVault(
activity,
LinkRequestContext.Builder()
.userEmail(email = "[email protected]") // Used to pre-populate the login screen if not already logged in.
.build()
)
⚠️ Opening the Vault before callingauthorize(...)
will bring up the Moneytree login site and create a session, but will not provide an access token to the SDK and in extend to the app. This is done by design and to offer a way to open the Vault outside the responsibility of your app. While in this state you can still callauthorize(...)
to get the access token.ℹ️ A snippet of the
LinkRequestContext.Builder
follows with all it's options and what they do:LinkRequestContext.Builder() // carries the search parameters the vault will search with in its services list .vaultOpenServicesOptions(VaultOpenServicesOptions) // The path to navigate to. Can be any of: // MoneytreeLink.VAULT_SERVICE, opens the vault directly to a specific connected service. // MoneytreeLink.VAULT_SERVICE_SETTINGS, opens the vault to the settings of a specific connected service. // MoneytreeLink.VAULT_SUPPORT, opens the customer support page of the vault. // When vaultOpenServicesOptions() is used the path is overridden, using the proper path. .path(String) // if provided and unauthorized the login page will have the email field pre-filled. .userEmail(String) // If the path is MoneytreeLink.VAULT_SERVICE, provide the service key you want to navigate to. // If the path is MoneytreeLink.VAULT_SERVICE_SETTINGS, provide the service id of the connected service's settings you want to navigate to. // Using this in any other case will result in an invalid url forcing the vault to it's default page. .pathSuffix(String) .build()
The LinkRequestContext.Builder
gives you the ability to provide a path(String)
with some parameters (pathSuffix(String)
or VaultOpenServicesOptions
) to open a specific page of the Vault.
Generally, the pages you can navigate to are:
- The top Vault page, where a list of your connected services and their top level information are displayed.
- The details page of a specific service.
- The settings page of a connected service, if for example the user needs to remove it from their account.
- The services list/search screen. Pre-search/filtering of the services can be performed depending on the configuration of
VaultOpenServicesOptions
provided invaultOpenServicesOptions(...)
.
The VaultOpenServicesOptions
object can be constructed using its Builder
:
VaultOpenServicesOptions.Builder()
.type("bank") // filter the list for the type of service you are looking for
.group("grouping_bank") // filter the list by the group the service belongs to
.search("aeon") // the actual term you are looking for (search bar contents)
.build()
All of type
, group
, search
are optional. You can build an "empty" VaultOpenServicesOptions.Builder().build()
to open the Vault directly in the services list without any filtering. The same effect can be achieved by adding the option with an empty string (""
)
ℹ️ The possible groups to search for are the following:
- grouping_bank
- grouping_bank_credit_card
- grouping_bank_dc_card
- grouping_corporate_credit_card
- grouping_credit_card
- grouping_credit_coop
- grouping_credit_union
- grouping_dc_pension_plan
- grouping_debit_card
- grouping_digital_money
- grouping_ja_bank
- grouping_life_insurance
- grouping_point
- grouping_regional_bank
- grouping_stock
- grouping_testing
You might want to provide an easy way to allow the user to access their Moneytree account settings from within your app. The SDK provides the interface function openSettings(Activity, String)
for that purpose.
The parameters required are:
activity
: the context used to open the in app browseremail
: used to pre-fill the login web form
MoneytreeLink.getInstance().openSettings(
activity,
"[email protected]"
)
⚠️ Please note that users may be required to re-authenticate in order to access Account Settings. This can be by re-entering their email and password or via Login Link, described below.
ℹ️ As described in Passwordless Sign Up/Login and Login Link you can perform settings navigation using Login Link.
The SDK, since v6.0, offers a new centralized callback system (delegate) that takes care of moving the required events and any data that they might need to hold. Your application simply needs to implement for these in a location that will respect the Android lifecycle (most of the time onCreate
of your component). This will ensure that callbacks will be received under all events that might cause a restart of your component, like configuration changes or process death due to memory pressure.
Internally this system holds a list of listeners and sends the events to all of them. This means that, for example, you can have a listener listening to specific events on the application level and another one in your Activity or Fragment.
The interface of this listener is the LinkResultListener
and can be added by calling addOnLinkResult(LifecycleOwner, LinkResultListener)
, where:
lifecycleOwner
is used to follow the lifecycle of the component setting up the listener and remove it in itsonDestroy()
call.onLinkResult
the listener itself.
To listen to these event you have 2 options:
-
You can directly use
addOnLinkResult(...)
and manually check for combinations ofLinkResult
,LinkEvent
, andLinkError
to know what it is that you are receiving.MoneytreeLink.getInstance().addOnLinkResult(this) { result -> when { result is LinkResult.Authorized -> { // Authorized and you token lives here: result.token?.value // If null you are using Code Grant auth flow (Deprecated) } result is LinkResult.Event && result.event == LinkEvent.LoggedOut -> { // Logged out } result is LinkResult.Event && result.event == LinkEvent.VaultClosed -> { // The Vault has closed } result is LinkResult.Event && result.event == LinkEvent.ExternalOAuthAdded -> { // Auth credential that launches in full browser has just been added. } result is LinkResult.Error -> { val error = result.moneytreeLinkException.error if (error == LinkError.UNAUTHORIZED) { // User didn't complete authorization process. } else { // Look into what an error happened } } else -> Unit } }
-
You can use a set of Kotlin extension functions provided.
with(MoneytreeLink.getInstance()) { onAuthorized(context) { token -> // PKCE auth flow completed if token != null, get your token here: token.value // Otherwise, it should be Code Grant (Deprecated) } onLoggedOut(context) { // Logged out } onEvent(context) { event -> when (event) { LinkEvent.ExternalOAuthAdded -> { // Auth credential that launches in full browser has just been added. } LinkEvent.LinkWebSessionStarted -> { // You can do here whatever needs to happen before the in app browser opens } LinkEvent.LinkWebSessionFinished -> { // Whatever needs to happens after the browser closes. // This has no specific meaning. It simply indicates that the browser has closed // For example VaultClosed should be used if you need to refresh data } LinkEvent.RequestCancelled -> { // This event is transmitted when the in app browser closes without a scheme triggering // a flow. This means that the browser close button or system back button were used. } LinkEvent.VaultOpened -> { // Specific event to indicate that the browser is opening the vault. } LinkEvent.VaultClosed -> { // The Vault closed, the user might have done something, update or something... } LinkEvent.LoggedOut -> { // This is the event for a successful logout. // The extension function onLoggedOut is a shortcut of this. } } } onError(context) { e -> if (e.error == LinkError.UNAUTHORIZED) { // User didn't complete authorization process. } else { // Look into what an error happened } } }
If you would like to use the above extension from Java (Java 8 required), we are providing the following way:
MoneytreeLink link = MoneytreeLink.Companion.getInstance();
MoneytreeLinkExtensions.onAuthorized(link, this, (token) -> {
// Your token is in: token.getValue() if PKCE
});
MoneytreeLinkExtensions.onEvent(link, this, (event) -> {
if (event == LinkEvent.LoggedOut) {
// Logged out
}
});
We offer the ability to register a device token with our services. If you do so the users will be able to receive push notifications with useful information about their account. Such registration should be done after the user has given permission to access their data from your app, while you should unregister the token when the user logs out, or takes other destructive actions.
⚠️ This feature is available only when using the PKCE OAuth flow and in extension when using LINK Kit
The best place to register for the token would be when you receive the callback for a successful authorization
For example when using Core SDK with PKCE
with(MoneytreeLink.instance) {
onPkceAuthorized(context) {
// Register for notifications
val deviceToken = yourMethodToGetDeviceToken()
MoneytreeLink
.instance
.registerRemoteToken(
deviceToken,
object : Action {
override fun onSuccess() {
// callback
}
override fun onError(exception: MoneytreeLinkException) {
// callback
}
}
)
}
}
ℹ️ `registerRemoteToken(...) is clever enough to do nothing is an old token is used again or unregister an old token if a new one is provided, so you do not need to care about that.
Similarly you can call unregisterRemoteToken(String, Action?)
when logging out to ensure no token is still active.
When using only LINK Kit and want to register for notification you can do a similar operation in the onLaunched()
event of the LINK Kit launcher:
LinkKit.getInstance().launch(
activity = activity,
authenticationMethod = AuthenticationMethod.Credentials,
listener = object : LinkKit.LinkKitListener {
override fun onLaunched() {
val deviceToken = yourMethodToGetDeviceToken()
MoneytreeLink
.instance
.registerRemoteToken(
deviceToken,
object : Action {
override fun onSuccess() {
// callback
}
override fun onError(exception: MoneytreeLinkException) {
// callback
}
}
)
}
override fun onError(exception: MoneytreeLinkException) {
}
}
)
