Webhook Events and Notifications

Messaging Webhooks (associated with Messaging API)

After the webhook is set for the number, it will receive notifications about messaging events. These events are grouped and can be used for:

  • Inbound Message Notifications: Use it to get a notification when a customer performs an action, such as:

  • Sends a text message to the business

  • Sends an image, video, audio, document, or sticker to the business

  • Sends contact information to the business

  • Sends location information to the business

  • Clicks a reply button set up by the business

  • Clicks a call-to-actions button on an Ad that Clicks to WhatsApp

  • Clicks an item on a business' list

  • Updates their profile information such as their phone number

  • Asks for information about a specific product

  • Orders products being sold by the business

Message Status Notifications: Use it to monitor the status of sent messages.

  • delivered

  • read

  • sent

If a webhook event isn't delivered for any reason (e.g., the client is offline) or if the webhook request returns a HTTP status code other than 200, we retry the webhook delivery. We continue retrying delivery with increasing delays up to a certain timeout (typically 24 hours, though this may vary), or until the delivery succeeds.

For Cloud API, the object is always whatsapp_business_account but the field will be indicative of the type of information being sent.

{
  "object": "whatsapp_business_account",
  "entry": [{
    "id": "WHATSAPP_BUSINESS_ACCOUNT_ID",
    "changes": [{
      "value": {
        "messaging_product": "whatsapp",
        "metadata": {
          "display_phone_number": PHONE_NUMBER,
          "phone_number_id": PHONE_NUMBER_ID
        },
        "contacts": [{
          "profile": {
            "name": "NAME"
          },
          "wa_id": PHONE_NUMBER
        }],
        "messages": [{
          "from": PHONE_NUMBER,
          "id": "wamid.ID",
          "timestamp": TIMESTAMP,
          "text": {
            "body": "MESSAGE_BODY"

          "type": "text"
        }]
      },
      "field": "messages"
    }]
  }]
}

[will be deprecated] For On-premise API, the object will be contacts and messages, errors, or statuses and pricing.

{
  "contacts": [{
    "profile": {
      "name": "NAME"
    },
    "wa_id": "WHATSAPP_BUSINESS_ACCOUNT_ID"
  }],
  "messages":[{
    "from": "PHONE_NUMBER",
    "id": "wamid.ID",
    "timestamp": "TIMESTAMP",
    "text": {
      "body": "MESSAGE_BODY"
    },
    "type": "text"
  }]
} 

Text Messages

See Text Messages.

The following is an example of a text message you received from a customer:

Example Payload
{
  "object": "whatsapp_business_account",
  "entry": [{
      "id": "WHATSAPP_BUSINESS_ACCOUNT_ID",
      "changes": [{
          "value": {

                  "profile": {
                    "name": "NAME"
                  },
                  "wa_id": PHONE_NUMBER
                }],
              "messages": [{
                  "from": PHONE_NUMBER,
                  "id": "wamid.ID",

                }]
          },
          "field": "messages"
        }]
  }]
}

Reaction Messages

See Reaction Messages.

The following is an example of a reaction message you received from a customer. You will not receive this webbook if the message the customer is reacting to is more than 30 days old.

Example Payload
{
"object": "whatsapp_business_account",
"entry": [{
    "id": "WHATSAPP_BUSINESS_ACCOUNT_ID",
    "changes": [{
        "value": {
            "messaging_product": "whatsapp",
            "metadata": {
                "display_phone_number": PHONE_NUMBER,
                "phone_number_id": PHONE_NUMBER_ID
            },
            "contacts": [{
                "profile": {
                  "name": "NAME"
                },
                "wa_id": PHONE_NUMBER
              }],
            "messages": [{
                "from": PHONE_NUMBER,
                "id": "wamid.ID",
                "timestamp": TIMESTAMP,
                "reaction": {
                  "message_id": "MESSAGE_ID",
                  "emoji": "EMOJI"
                },
                "type": "reaction"
              }]
        },
        "field": "messages"
      }]
}]
}

Note that for reactions, the timestamp value indicates when the customer sent the reaction, not when the webhook was generated.

Media Messages

See Media Messages.

When a message with media is received, the WhatsApp Business Platform downloads the media. A notification is sent to the Webhook once the media is downloaded.

The Webhook notification contains information that identifies the media object and enables you to find and retrieve the object. Use the media endpoints to retrieve the media.

Example Payload
{
  "object": "whatsapp_business_account",
  "entry": [{
      "id": "WHATSAPP_BUSINESS_ACCOUNT_ID",
      "changes": [{
          "value": {
              "messaging_product": "whatsapp",
              "metadata": {
                  "display_phone_number": PHONE_NUMBER,
                  "phone_number_id": PHONE_NUMBER_ID
              },
              "contacts": [{
                  "profile": {
                    "name": "NAME"
                  },
                  "wa_id": "WHATSAPP_ID"
                }],
              "messages": [{
                  "from": PHONE_NUMBER,
                  "id": "wamid.ID",
                  "timestamp": TIMESTAMP,
                  "type": "image",
                  "image": {
                    "caption": "CAPTION",
                    "mime_type": "image/jpeg",
                    "sha256": "IMAGE_HASH",
                    "id": "ID"
                  }
                }]
          },
          "field": "messages"
        }]
    }]
}

When you receive a sticker, you will get the following notification:

{
  "object": "whatsapp_business_account",
  "entry": [
    {
      "id": "ID",
      "changes": [
        {
          "value": {
            "messaging_product": "whatsapp",
            "metadata": {
              "display_phone_number": "PHONE_NUMBER",
              "phone_number_id": "PHONE_NUMBER_ID"
            },
            "contacts": [
              {
                "profile": {
                  "name": "NAME"
                },
                "wa_id": "ID"
              }
            ],
            "messages": [
              {
                "from": "SENDER_PHONE_NUMBER",
                "id": "wamid.ID",
                "timestamp": "TIMESTAMP",
                "type": "sticker",
                "sticker": {
                  "mime_type": "image/webp",
                  "sha256": "HASH",
                  "id": "ID"
                }
              }
            ]
          },
          "field": "messages"
        }
      ]
    }
  ]
}

Unknown Messages

It's possible to receive an unknown message callback notification. For example, a customer could send you a message that's not supported, such as a disappearing message (in which case Meta notifies the that the message type is not supported).

Example Payload

The following is an example of a message you received from a customer that is not supported.

                      "title": "Unsupported message type"
                    }],
                   "type": "unknown"

Template held for Pacing

Example Payload

Messages will have one of the following statuses which will be returned in each of the messages objects

  • "message_status":"accepted" : means the message was sent to the intended recipient.

  • "message_status":"held_for_quality_assessment": means the message send was delayed until quality can be validated and it will either be sent or dropped at this point.

      {

      "contacts": [
        {
          "input": "16505555555",

The Messaging webhook receives an event when the message is sent, delivered, and read.

The order of these events may not reflect the actual timing of the message status. View the timestamp to determine the timing, if necessary.
