 # Sigma Embed-SDK for React
+
 Sigma provides several methods to allow users and developers to interact with its systems including web-ui, REST API, Javascript Embed API and an SDK for the React framework.
 
 The Embed-SDK for React offers a higher-level, developer-friendly interface that simplifies integration into applications, in contrast to Sigma’s lower-level JavaScript Embed-API, which provides more granular control but may require additional coding
