404 ENTITY_NOT_FOUND Bitrix24 returned "not found"; the portal code is in error.b24Code

401 TOKEN_MISSING The API key has no Bitrix24 tokens configured

The full list of general API errors — Errors.

Known specifics

The call may make you a member. If the message's chat allows auto-join — for example, a comment chat, a collab or a task chat — the call adds the current user as a member, just as opening the chat in the Bitrix24 interface does. The call therefore counts as a write.

Rating any message. Bitrix24 accepts a rating for any message and returns result: true: the rating is sent as a Bitrix24 event, and CoPilot handlers process it for answers in a CoPilot chat. This endpoint cannot read a rating back.
