Error Codes
Code | Description |
---|---|
400 | Bad Request - Invalid parameters |
401 | Unauthorized - Invalid or missing API key |
404 | Not Found - Session, chat or message not found |
429 | Too many requests - Rate limit exceeded |
500 | Internal server error |
Notes
- Phone numbers must be in international format (e.g., "+1234567890") or a group JID for groups.
- The @c.us suffix (for contacts) or @g.us (for groups) is automatically added by the API if not provided for the
to
field. - The
messageId
must be a valid ID of a message within the specified chat. - This action is asynchronous and might take a moment to reflect on the sender's device.
