Plausible-to-Fivetran Cloud Function

A Google Cloud Function that fetches analytics data from Plausible and streams it into Fivetran. This function handles incremental syncs, respects timezones configured in your Plausible dashboard, and automatically merges data into a timeseries table within Fivetran.

Overview

This repository contains a Node.js function meant to be deployed on Google Cloud Functions. It leverages Fivetran’s function connector to sync Plausible analytics data on a regular schedule. The function:

• Reads the plausibleApiKey and siteId secrets from the Fivetran request body.
• Queries Plausible’s v2 analytics API to retrieve incremental hourly data.
• Returns data in a format Fivetran can ingest (including a state object, table schema, and indicators for additional data).

---

Setup and Deployment

Use the instructions in the official Fivetran Google Cloud Functions setup guide to deploy this function. Make sure to:

1. Provide this repository’s code as your function source.
2. Set the entry point to syncWithPlausible.
3. Configure two secrets in Fivetran’s Configuration:
   • plausibleApiKey: Your Plausible API key
   • siteId: The Plausible site ID you want to fetch analytics for

---

Configuration

• REPORTING_TIMEZONE
  Set within the code to match your Plausible dashboard’s timezone. Default is Europe/Berlin.

• PAGE_SIZE
  The number of records fetched per API call. Default is 1000. You can adjust this in the code to optimize for your data volume and performance.

• State Management
  Fivetran manages a state object that the function updates. The function uses:

  • state.lastDateTime to know the last timestamp synced
  • state.lastOffset for pagination across Plausible’s API

---

Usage

Once deployed and configured:

1. Initial Sync

   • Fivetran calls the function with no state. The function fetches data starting from the earliest available date (or "all") until the latest.
   • It updates the Fivetran state with the newest timestamp retrieved (lastDateTime).

2. Incremental Sync

   • On subsequent calls, Fivetran includes the lastDateTime in the request state.
   • The function queries Plausible from lastDateTime to the current time, ensuring only new data is retrieved.

3. Data Destination

   • Fivetran creates or updates a plausible_timeseries table in your destination.
   • Columns include timestamp, visitors, pageviews, bounce_rate, visit_duration, and visits.

---

Testing the Integration

• Connection Test
  Fivetran’s Test Connection calls the function with setup_test = true. In this mode, the function performs a minimal API request to Plausible (requesting one row) to confirm credentials and endpoint availability.

• Local Testing
  You can also run the function locally with the Functions Framework:

  npm install
  npx functions-framework --target=syncWithPlausible --port=8080

  Then POST a request to http://localhost:8080/ to test the logic.
