Hi niubizai,

There must be something which is correct in the console application but wrong in the plugin. I would recommend you debug the plug-in. Few links:

Hi niubizai,

What about Dynamic 365 Customer Engagement? I think it is the better option.

Hi, The error message "The remote server returned an error: (400) Bad Request" is quite clear actually. That means, You are parsing and sending wrong request. Debug your code or use traces to see your final request body. Compare it with working postman request body.

yup i know its just state 400 bad request is quite not crm side error but the true is i was working with postman and crm both so i in postman test case is successful then i just move the request body inside my code and true is CRM self security bugs make the webrequest function become buggy so i have solve the problem using another way while waiting they solove the issue as well

thank you
