passing user name/created_by as a parameter to call rest api to create project from pl/sql

Summary:

passing user name/created_by as a parameter to call rest api to create project from pl/sql -

/fscmRestApi/resources/11.13.18.05/projects

Content (required):

I am calling create project api - /fscmRestApi/resources/11.13.18.05/projects - from pl/sql code.

Problem we are facing to capture who columns' values in oracle saas tables. It is capturing the user details in who column which was used to make call to REST api.

we want to capture the details of user in created_by and last_updated_by columns who has called our pl/sql procedure ( a parameter of username in custom procedure) to create project not the user used in REST API call.
