Hi,

Leadsourcecode and statuscode field value should not be in quote("1", "1"). It should be in below format.

{

"firstname" = "t";

"lastname" = "p";

"emailaddress1" = "t@p.com";

"subject" = "subject";

"leadsourcecode" = 1;

"statuscode" = 930720002;

}

Make sure you are passing correct optionset value for leadsourcecode and statuscode.

Bipin - Thanks for your prompt response. But still no luck. I am using NTLM authentication with a CRM System admin user. BTW, how to enable logs to see detailed errors?

Hi,

Can you download Postman tool and try the same thing in that.

www.postman.com/.../

Also, you mentioned that GET is working with NTML Authentication, only post is not working. Can you enable tracing on server and check for the logs. Also check event viewer on web server for the error details.

I found answer for this. Since I have Dynamics 365 on-premise with IFD and using ADFS 3.0. ADFS won't allow NTLM connections. Our environment is configured Claims based authentication. In order to make this Web API call to work on/from any application/client, first that application/client has to be registered on ADFS to get authorization code and then use that code to get access token to authenticate. It is really hard way of doing it. I managed with some old connector (Partner-Hosted IFD) which worked with SOAP service instead Web API. So, I am good for now to continue in a old fashion of using SOAP services.
