Hello,   I'm trying to send a POST API request using PROC HTTP through a Stored Process (UI), Since the user is already logged in, I want to use the same credentials instead of writing the username and password in \ /* Send http request from Stored Process */ PROC HTTP METHOD="POST" URL="http://application-name/SASComplianceSolutionsMid/.../...." CT="application/json" IN=input OUT=output WEBUSERNAME="username" WEBPASSWORD="password" /* AUTH_NEGOTIATE */ ; RUN; However this code responds with HTTP Status 403 - Forbidden, not sure about the reason,   I also tried to use the AUTH_NEGOTIATE option instead of the basic authentication option, but it didn't work as expected and it returns HTTP Status 401 - Unauthorized Access. I expected that it will use the same credentials for the logged-in user. HTTP Negotiate is an authentication extension that is used commonly to provide single signon capability to web requests. This is normally used in PROC HTTP when a password is not provided, since it will use the current user’s identity for authentication. Link Am I missing something? Or is it applicable to send the API request in such a way without determining a specific credential in the code?    Thanks. ... View more
