Topics covered: • Custom API Actions, Functions, and binding types • Caller privileges with ExecutePrivilegeName • IsPrivate and the distinction between metadata visibility and authorization • RequestId-based replay handling and idempotent operation results • Managed Identity Version 2 and assembly-bound Federated Identity Credentials • Token acquisition with IManagedIdentityService.AcquireToken() • Dataverse Business Events Catalog and asynchronous subscribers • Extension controls with AllowedCustomProcessingStepType • Independent testing of caller permissions, retries, and outbound access failures • Managed solution packaging for repeatable deployment For learners preparing for AB-400 and developers building Dataverse Custom APIs and event-driven integrations. #AB400 #Dataverse #PowerPlatform
