We are using Pega PDM (Pega cloud) 5.6.1. The current OOTB authentication setup is basic for the calls from Orchestartor server to candidate system. Understood that PDM OOTB supports only basic auth (doesn't support OAUTH) for the flow but we want to change this to OAUTH 2.0. Based on the analysis found that the "Deploy Application" task in the pipeline calls SystemManagement service package for creating restore point. As suggested in the post (https://support.pega.com/support-doc/open-access-manager-openam-integration-deployment-manager) we created a client registration for orchestrator in the candidate system and updated the generated client secret in an Authentication profile in orchestrator as well as referred the same auth profile in our deployment pipeline. Post this the deploy application task in the pipeline fails with a subsequent api call with 401 error (due to the authentication setup). So could someone share insights on the APIs called by the orchestartor when performing "Deploy Application" task ? or provide clear steps to change the authentication to OAUTH for calls from orchestartor server to candidate system

@Pallavi Gurram , any help is appreciated
