title: Whatsapp as a channel with Microsoft Bot Framework using Clickatell
body: <p>Working with a customer who wants to use Microsoft Bot Framework and "Whatsapp" as a channel. Though Whatsapp has released its <a href="https://www.facebook.com/business/m/whatsapp/business-api" rel="nofollow noreferrer">public business API</a>, it is still in limited public preview and Microsoft Bot Framework understandably doesn't yet support it. As an alternate, we are planning to use "Clickatell" for whatsapp integration, where Bot Framework would call the Clickatell APIs and enable integration with Whatsapp. Has anyone worked on this scenario and can throw some light on any challenges? such as how this custom channel would work and how security etc would be handled in the non-standard channel (Whatsapp)</p>
  
  <p>Thanks</p>
