Once I gave https in the URL, the error is no longer seen :) Re: Missing Required Headers error Hi Rao, The header is already present in the Raw request and it displays the value fine. But when I run the test, it fails with the error 'Missing required headers' . Am using the same exact test as my team member. It works for him, but not me :( Missing Required Headers error Am getting this error 'Missing Required Headers' in the response. But I can see in the Raw Request, that the Headers are sent. Here is the raw request : Client_id and client_secret are the headers that are being sent. POST https://abc.com/trec/restconsumer/v1/profile.do HTTP/1.1 Accept-Encoding: gzip,deflate Content-Type: application/json transaction_id: It8dozMcOKNx5HgfcvXkZXoUYM8k7Bxzmfms0n7faEbyELDXv Host: abc.com Accept-Encoding: gzip,deflate Content-Type: application/json transaction_id: It8dozMcOKNx5HgfcvXkZXoUYM8k7Bxzmfms0n7faEbyELDXv client_secret: abc client_id: abc Content-Length: 1997 Host: abc.com Connection: Keep-Alive User-Agent: Apache-HttpClient/4.1.1 (java 1.5) My colleague has posted the exact same request with the headers and his test seems to run fine. This same test worked few months ago with older version of SOAP. My current version is SOAPUI 5.5.0 . I tried uninstalling SOAPUI 5.5.0 and installed SOAPUI 5.4.0. Still no luck. Can you please help.
