Apps can only send requests to endpoints that are registered via the Developer Portal. This makes it possible for Canva to verify that the endpoints implement the signature verification security mechanism.
To register an endpoint:
- Navigate to an app via the Developer Portal.
- Set up a Base URL.
- Under the Endpoint allowlist label, click Add another endpoint.
- Enter the path of an endpoint, such as
/my/cool/endpoint.
Your changes are saved automatically.
Notes
- You can add up to 25 endpoints to an app.
- All endpoints must be served via the same Base URL.
- If you try to send a request to an endpoint that is not registered, an error is thrown.
