REST and OAuth 2.0 for authentication



When calling the pyGetOAuthResource activity for OAuth 2.0 client authentication an exception is produced: "Unable to open an instance using the given inputs." Is OAuth 2.0 supported by any Pega 7 release?

Error Messages

"Unable to open an instance using the given inputs."

Steps to Reproduce

1.Create OAuth Client instance
2.Create activity to call "Data-Admin-Security-OAuth-Client.pyGetOAuthResource"
3.Exception caught while running the above activity

Root Cause

The root cause of this problem is defect/misconfiguration in the PRPC operating environment. PRPC does not support OAuth 2.0.


PRPC only supports OAuth 1.0 at the present time.
