I'm calling the CRM REST API for changes in AuditSet via WCFWebHttp from two different BizTalk applications. Everything is configured identically for both applications

One application works fine without any exceptions, but the "new" one fails intermittently with the following exception:

I've used Fiddler to monitor the calls and there are no differences between calls which are successful and those which fails

  • And it only fails intermittently when using BizTalk calls it? Or have you not tried it enough with Fiddler to reproduce it? From what you have said and the error, it looks like it may be an issue at the CRM side to do with the password hashing, and nothing that BizTalk is doing that is causing it. – Dijkgraaf Jun 27 '17 at 01:13
  • Yip, only fails in about 5% of the BT calls. If I paste the URI into a browser (impersonating the service account) I can invoke the service successfully every time. – The Curious Coder Jun 27 '17 at 03:29
