I am trying to setup my first SOAP request in Postman. I am getting this response.
![CDATA[SECU1075: An error was discovered processing the wsse:Security
SECU1096: Could not find a WS-Security Header
Steps taken so far.
- Added a certificate under File…Settings…Certificates
- Created a Collection
Question: What authentication do I select to have Postman add WS Security Headers for a certificate?
