Send an Interactive Button Message on WhatsApp

An Interactive Button message is similar to a Button Template except this is not a template and hence doesn’t need an approval. But this type of message can only be sent as a reply - during the 24 hours window of a chat.

Messages including up to 3 options —each option is a button. This type of message offers a quicker way for users to make a selection from a menu when interacting with a business. Reply buttons have the same user experience as Button Template messages.

Interactive Button Message can have an optional header, a text body and an optional footer.

​
Send Interactive List Message on WhatsApp

Messages including a menu of up to 10 options. This type of message offers a simpler and more consistent way for users to make a selection when interacting with a business.

List Messages are best for presenting several options, such as:

  • A customer care or FAQ menu
  • A take-out menu
  • Selection of nearby stores or locations
  • Available reservation times
  • Choosing a recent order to repeat

​
Response for Send Message

Response will include the message id and the status of the message.

JSON
{
  "status": "200",
  "statusText": "Accepted",
  "messageId": "068a169a-f1fe-11ea-9b75-42010a67e00f"
}

Message response status accepted means that the message has been accepted by the channel (WhatsApp in the above examples). It just means the request seems valid and will be processed.

The actual delivery updates on the message - if and when it was delivered, failed, read or seen etc will come later as and when it happens. We do track those and display them correctly on the Zoko Chat Dashboard.

But if you are an API only user, you would need the help of webhooks to get notified of those updates.
