SMS Gateway - Vonage API for WhatsApp

The Vonage API for WhatsApp SMS Gateway delivers SMS messages internationally to WhatsApp users. You can get more information about the features of the WhatsApp Business API here:

There are some important differences that are unique to WhatsApp compared with the regular Vonage SMS API. WhatsApp divides messages into two different types: Template messages and Session messages. These determine when you can initiate a message to a WhatsApp user.

You can get further information on Template messages and Session messages here:

fmSMS supports using the Vonage WhatsApp Messages API Sandbox for testing sending WhatsApp messages for free whilst you are developing an integration with WhatsApp. Not all features of the production Messages API are supported by the Messages API Sandbox: you can get more information about the Messages API Sandbox and the supported features here:

To enable Sandbox mode in fmSMS click the Use Sandbox Mode checkbox in the Accounts Form layout:

Incoming Messages/Replies

You can get incoming messages/replies to your Vonage number into the fmSMS file in in several ways:

Using Webhooks is the preferred method as it saves you from having to poll/check for any new messages - with Webhooks new messages are forward to fmSMS automatically by Vonage as they are received.

Vonage Webhooks Setup

To receive incoming SMS messages to your Vonage number, including replies to previously sent messages, you will need to use the supplied incomingMessage.php webhook file to act as the webhook receiver. See our Webhooks guide for what you need to do host the incomingMessage.php file on your chosen web server. Once you have the publicly accessible URL for this file you can enter this into your Vonage account settings by creating an Application and entering the URL for the Messages Inbound URL. You can learn more about Messages API webhooks in the documentation

You can also test Webhooks with the Messages API Sandbox by entering the URL to the php file in your Sandbox Dashboard here:
