Error Codes

When a Send API request fails, you'll receive a JSON response describing the corresponding error code and message. Messenger Platform errors are grouped by code, with a different message depending on the error condition.

Below is a list of common errors that you should consider handling at run-time.

Example

{
  "error": {
    "message": "Invalid OAuth access token.",
    "type": "OAuthException",
    "code": 190,
    "error_subcode": 1234567,
    "fbtrace_id": "BLBz/WZt8dN"
  }
}
