I am looking to use Microsoft Bot Framework in my application. However, I have a custom UI chat control (designed according to my requirements) where I need to hook up this bot.(instead of having pre-configured channels like slack or skype).
Is there a client sdk for web (preferably in angular) and/or mobile available for this purpose?
Take a look at DirectLine.
The Direct Line API is a simple REST API for connecting directly to a single bot. This API is intended for developers writing their own client applications, web chat controls, or mobile apps that will talk to their bot.
