Hi,

I am trying to integrate salesforce with biztalk using REST call.

For the authentication I am using the recomended way of having a custom WCF extension to add headers.

https://developer.salesforce.com/page/Calling_the_Force.com_REST_API_from_BizTalk_Server

But when posting

var response = authClient.PostAsync("https://login.salesforce.com/services/oauth2/token", content);

I get exception as:

The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

I have all the required setup and values for the OAuth.

Has anyone encountered the same. Do I need to have any certificate

TO Add...

I am using my developers salesforce account for the test purpose..
