I am trying to use the Orchestrator API configured for external application providing the required scopes. Everything is going well, all the requests are working, but when I try to get the alerts it is always coming empty, the strange behavior is that on swagger it is working fine and the alerts are fetched on swagger but on postman/studio the number of alerts on response is always empty.
__
URL of requests :: https://{orch url}/odata/Alerts
I think the type of Scope in External Application matters. Got the same error with Postman registered as Confidential - Application Scope. But works fine with Confidential - User Scope and NonConfidential - User Scope. May be you can try the same?
