Hello,

POST /api/v2/conversations/messages/{conversationId}/communications/{communicationId}/messages requires an access token associated with a user context (OAuth token).
I mean it needs to be a token obtained by a user through an OAuth Grant flow like Implicit Grant, Authorization Code Grant, PKCE Grant. It has to be a user who is a participant in this conversation.

Client Credentials Grant is for server-to-server.

Is this platform Api defect ?

No. This API Endpoint does not support the use of an access token obtained via an OAuth Client Credentials Grant flow.

Regards,
