Error 131051

131051

Unsupported Message Type

Sender issue:This is a problem with your business account or API configuration.

What this error means

The message you tried to send uses a format, type, or set of parameters that WhatsApp does not support. This is typically an API integration issue rather than a recipient problem.

Common causes

  • •Using an unsupported message type in the API request.
  • •Incorrect API parameters or malformed request body.
  • •Attempting to send a message type not yet supported in your API version.

How to fix

  1. Review the WhatsApp Cloud API Messages reference for supported message types.
  2. Check your API request body for syntax errors or unsupported parameters.
  3. Ensure your API version supports the message type you are trying to send.
