I am working on building an automated API test of OAuth 1.0a… the Application has many redirects that I am following to process the OAuth 1.0a dance. My question is the server is ultimately provdiing me with the message “oauth_problem=parameter_absent” when processing the oauth-authorize GET. Here’s a redacted (Redacted values are in bold and italic) example of that message - I don’t see any missing parameter based on the Oauth 1.0a Core specification:
Also following screen shot shows the OAuth1.0 settings in postman - note that all environment variables have valid values based on prior steps in the dance
Any pointers on what to try next would be greatly appreciated.
