          "type": "unknown"
      }]
}

Inbound Media Message Notifications

When a message with media is received, the WhatsApp Business API Client will download the media. A notification is sent to your Webhook once the media is downloaded. This message contains information that identifies the media object and enables you to find and retrieve the object. Use the Media endpoint with the media's id to retrieve the media.

This section shows examples of messages that are received with media.

Example: Message with Image Received

The following is an example inbound message that contains an image. See the media object section below to learn more about the different media types.

         "mime_type":"image/jpeg",
         "sha256":"29ed500fa64eb55fc19dc4124acb300e5dcc54a0f822a301ae99944db"
         "caption": "Check out my new phone!"},
      "timestamp":"1521497954",
      "type":"image"
  }]
}

The caption field is optional for media messages. It is only included if the user has set a caption.

        "timestamp": "1521827831",
        "type": "voice",
        "voice": {

}

Inbound Replies to Sent Messages

Users can respond to a specific message in WhatsApp. For the business to understand the context of a message reply, we include the context object. This context object provides the id of the message to which the customer replied and the WhatsApp ID of the sender of the original message.

Replying to Messages contains more information.

Example: Customer Replied to Your Message

The following is an example of an inbound message that is a reply to a message that you sent. See the context object section below for more information.

{
  "contacts": [ {
    "profile": {
        "name": "Kerry Fisher"
    },
    "wa_id": "16315551234"
  } ],
   "messages":[{
      "context":{
         "from":"16315558011",
         "id":"ABGGFlA5FpafAgo6tHcNmNjXmuSf"
         },
      "from":"16315551234",
      "id":"gBGGFlA5FpafAgkOuJbRq54qwbM",
      "text":{"body":"Yes, count me in!"},
      "timestamp":"1521499915",
      "type":"text"
  }]
}

The text field is optional for media messages. If it exists, the text value is the caption of the sent media or the body of the response, if the response is a text message.

User Deleted Message

Beginning with v2.21.3, in the case where a user deletes a message they have sent to you, you will receive a message status notification indicating the message was deleted. The message will be deleted automatically from the WhatsApp server, but please ensure that the message is also deleted from your system if it was downloaded. See Message Maintenance for more information on how to do this.

Inbound System Messages

System messages are generated by the system when some event happens, for example a user added/removed another user or leaves a group, etc. See the system object section below for more information.

{
    "messages": [
        {
            "from": "16506448470",
            "group_id": "16315558032-1530825318",
            "id": "ACELFjFVWAMqFTCCUxgDM3N5cy0xNjMxNTU1ODAzMi0xNTMwODI1MzE4QGcudXMtMTUzMDgyNTU4NzI5OS1hZGQtMBGGFlBkSEcP",
            "system": {
                "body": "+1 (650) 387-5246 added +1 (650) 644-8470",
                "group_id": "16315558032-1530825318",
                "operator": "16503875246",
                "type": "group_user_joined",
                "users": [
                    "16506448470"
                ]
            },
            "timestamp": "1530825587",
            "type": "system"
        }
    ]
}

For example, the following system messages were received when (1) a user joined a group and (2) when a group administrator added a group icon.

The following is an example of a customer replying to a message that contained mentions. The context object contains the numbers mentioned in the original message. The reply in the text object mentions the same numbers again.
