SEQ-4a Post Screen a case get Error 401 Unauthorized
Hi, Try to implement Screen a case like sample SEQ-4a. Post request get Error 401 Unauthorized. I find the sample authorisation header string does not contains content-type and content-length as described as in the Quick Start. My question is if this is the matter for the case. Please help. Thanks. John
Hi, i have found the problem and got this issue resolved. Basically it is the the HTTP component bug does not stream string parameters in order. Also there is another reasons cause the body string not compatible with the REST server. Thanks a lot for the help. John
Hi John,
There are a number of reasons you may receive a 401 status. Note some of the PUT/POST requests do no have a body, hence do not require content length... I suggest, if possible, share the code you wrote that is not working...also note that one of your groups is setup as a Zero Footprint group and so screening a case will not be permitted in that group, use one of the other groups you've setup.

Hi Brian,
I use the postman default group id in the pilot environment.
