I am trying to create ET - JB custom activity. My preferred technology is .Net and language is C#. I reviewed KBs and documents however didn’t find any helpful resource which can walk me through the steps. The one I found is created for node.js/PostMonger

I tried creating hello world in .net however neither the custom activity nor the custom trigger appeared in journey Builder canvas.





It seems that we are forced to use Node.js/ PostMonger in order to create custom activity and custom trigger for Journey Builder.

Please help and suggest if there is a way we can create JB Custom Activity and trigger using .Net and C#.

I don't believe using Postmonger is required; it's just a solution for nodejs custom activities. Your c# app will just need to emulate postmonger functionality.
