Webhooks Implementation in PeopleSoft

Dear Team,

Objective: We would like to implement Webhooks for all the leave requests submitted by the users in PeopleSoft(PS).

Usecase: when a user submits a leave request in PS, the system should invoke a callback URL to trigger the process in the third-party application. Similarly, when an Approver takes any action, it should invoke another callback URL with payload data.

Question: We are looking for a solution to implement Webhooks, with limited changes to the existing functionality/setup. Any pointers or solution approaches are greatly appreciated.

Thank you.
