POST /v1/oauth/introspect — canva-connect-api

v3

oauth

Introspect an access token to see whether it is valid and active. You can also verify some token properties, such as its claims, scopes, and validity times.

Requests to this endpoint require authentication with your client ID and client secret, using one of the following methods:

Basic access authentication (Recommended): For basic access authentication, the {credentials} string must be a Base64 encoded value of {client id}:{client secret}.
Body parameters: Provide your integration's credentials using the client_id and client_secret body parameters.

This endpoint can't be called from a user's web-browser client because it uses client authentication with client secrets. Requests must come from your integration's backend, otherwise they'll be blocked by Canva's Cross-Origin Resource Sharing (CORS) policy.

The "not before" time of the token, which specifies the time before which the access token most not be accepted, as a Unix timestamp in seconds.

jtistring
