How can my business validate whether a phone number is enabled as a WhatsApp user?

At the moment, Clickatell does not offer an API to check whether a phone number is WhatsApp enabled or not. We will, however, perform a check on your behalf before attempting to send a message from your business to the end user. If the number is not enabled, we will fail that message and return an error code to you.
