Hello @walaareafaee ,
I hope you doing good.
I suggest first you hit webhook url on postman to see whether url is running properly or not
Step 1: Method should be post & add below url in postman.
http://[your-ip-address]:[port-no]/webhooks/rest/webhook
Step 2: In body of postman { “sender”:“user”, “message”:“hi” }
If it is working then add http://[your-ip-address]:[port-no]/webhooks/rest/webhook in your ui part of chatbot & as you have to keep chatbot folder on IIS as we keep other project folder to run application else within application folder.
