Troubleshooting WhatsApp

When a message cannot be sent over MessageBird's WhatsApp Business API, the status will change to “rejected” or “failed”, and any additional details available will be provided via an error object attached to the message that indicates the code and a description of the error.

The API response will look similar to this:

{
"id": "5f3437fdb8444583aea093a047ac014b",
"conversationId": "2e15efafec384e1c82e9842075e87beb",
"channelId": "853eeb5348e541a595da93b48c61a1ae",
"type": "text",
"content": {
"text": "This is a test WhatsApp message"
},
"direction": "sent",
"status": "failed",
"error": {
"code": 302,
"description": "The contact is not registered on WhatsApp."
}
"createdDatetime": "2018-08-28T15:52:41Z",
"updatedDatetime": "2018-08-28T15:52:58Z"
}

WhatsApp error codes for common delivery errors are listed below:
