POST /configuration

API reference for the "/configuration" endpoint.

If an app supports authentication and has a publish extension, Canva sends a POST request to the following endpoint when a user opens the extension:

<authentication_base_url>/configuration
bash

The purpose of this request is to check if the user is authenticated with the destination platform.

If the user is authenticated, the extension continues to load. If the user is not authenticated, Canva renders a Connect button. The user can click this button to start the authentication flow.

To learn more, refer to Authentication.

Notes

  • Extensions must respond to this request within 8 seconds.
  • When sending this request, Canva replaces <authentication_base_url> with the app's Authentication base URL. You can configure the Authentication base URL via the app's Authentication page.
  • Extensions should meet the UX guidelines.
