Custom APIs

Custom APIs offer a new code-first way to define messages that you can add to Dataverse web services. Conceptually, Custom APIs are an extension to Custom Actions that have provided a no-code way to include custom messages.

Please note that Custom APIs is still a feature in preview.

While Custom Actions allowed you to define your API using the synchronous workflow engine, Custom APIs uses a plugin instead. Custom APIs also add a lot of extra configuration options compared to Custom Actions, including the ability to require a specific privilege to call the API, restrict how custom plugins can be attached to it or hide it from metadata discovery entirely.
