Hi @carsten-czarski-oracle
I want to create a Rest Data Source using token generated from fusion, Instead of passing Credentials or Basic Auth.
I have followed the below steps.

I have selected Oracle SaaS Rest Service as Rest Source Type.
In the page rendering I have created a process, to generate a token.

To capture token I have created an application item and when I run the page, in session I could see that token was successfully captured to application Item.

In Authentication, what changes do I need to make to create a Rest Data Source using Token generated from fusion.
Is there any other way to create Rest Data Source using token generated from fusion ?
Note: Token is dynamic.
Thanks and Regards
