}Authorizations
Every request authenticates with an API key: Authorization: Bearer {API_KEY}. App endpoints take an app API key; knowledge endpoints take a knowledge base API key (Get Started).
Keep keys server-side; never embed them in client code. Requests with a missing or invalid key fail with HTTP 401 (unauthorized).
Path Parameters
ID of the message to give feedback on. Get message IDs from List Conversation Messages.
Body
application/json
Request body for submitting message feedback.
End-user identifier, defined by your app and unique within it. Must match the user that received the message, since feedback is scoped to that end user. See End User Identity.
Optional text feedback providing additional detail.
Feedback rating. Set to null to revoke previously submitted feedback.
Available options:
like, dislike, null Response
Operation successful.
Operation result. Always success.
