Custom data connection for QnA Maker


This video blog (vBlog) is an extension of Karthik Bharathy's 'PowerBots - Creating smart apps with PowerApps and Microsoft Bots'. This vBlog focus on the following three topics

  1. QnA - Creating a new service in QnA and also provides the URL for making the POST call. This is where we get the subscription key as well.
  2. POSTMAN - Building a custom JSON file using POSTMAN. I recommend signing up, downloading and installing the desktop application.
  3. PowerApps - Create the custom connector in PowerApps.






This article focus on building the connection and creating Bots using PowerApps only. For building a web interface Bot you can use Microsoft's BOT Framework (Preview) or Azure Bot Service.


Would you please share the documentation for how to create the APP
