I would like to find out what is the usage of the check otk values button for. The button is found under check gateway configuration within the API Portal.
I can't find explicit documentation on 'Check OTK Values' but it is connected with enabling Oauth authentication for APIs published by the Portal. Some back ground information is here:-
Manage API Keys with CA API Portal - CA API Management OAuth Toolkit - 3.5 - CA Technologies Documentation
Authenticate APIs - CA API Developer Portal - 3.5 - CA Technologies Documentation
Support have used this button to confirm valid setup, we usually check the portal's catalina.out log file at the time it is pressed.
Thanks for your answer.
