Request Body

24 hour WhatsApp restriction

If the recipient has not initiated the conversation first within the last 24 hours you CAN NOT send the messages to them. In this case, you MUST use templated message API /v1/businesses/{businessId}/send/whatsapp_templated_messages.

  • Generally, you use /v1/businesses/{businessId}/send/messages to reply to the customers who already messaged you first.

  • You use /v1/businesses/{businessId}/send/whatsapp_templated_messages to initiate with the customer first.

Select the WhatsApp number you want to send from

The endpoint supports an optional sender field in the body. If you have multiple WhatsApp phone numbers with Connectly you can choose which one you want to send the message from. The payload needs to contain the optional sender object specifying the phone number in the id section and channelType as whatsapp:

{
  "sender": {
    "id": "+14151111234",
    "channelType": "whatsapp"
  },
  "recipient": {
    "id": "+16044441111",
    "channelType": "whatsapp"
  },
  "message": {
    "text": "Hello, this is a text message!"
  }
}

Header Media

Both list and quick reply messages use the same header parameter structure. Here is an example of an image header:

"header": {
    "attachment": {
        "type": "image",
        "url": "https://cdn.connectly.ai/26fa/26fa1308-d328-41c9-a6a1-d5f4225a3768",
    }
},

This is an example of a document header with a filename:

"header": {
    "attachment": {
        "type": "document",
        "url": "https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf",
        "filename": "feeeelsss"
    }
},
