The API Reference documents every endpoint of the Admin API — the REST interface for programmatically managing an instance. Each page describes a single operation, including its HTTP method, path, parameters, and response schema, generated directly from the Admin API’s OpenAPI specification. For the concepts behind these endpoints — authentication, the /api.rsc/ endpoint convention, CORS, and filtering — start with the Admin API guide in the Arc User Guide. This reference then documents the individual operations, grouped into resources and actions.

​
Resources

Resources are objects you query, create, update, and delete with the standard HTTP methods (GET, POST, PUT, DELETE), each exposed at /api.rsc/<resource>.

​
Actions

Actions go beyond resource CRUD — administrative and connector operations invoked with an HTTP POST to /api.rsc/<actionName>. They cover tasks such as cleaning up logs and folders, copying connectors and workspaces, creating and exchanging certificates, importing and exporting settings and encryption keys, requeuing and counting messages, sending and receiving files, and retrieving transaction logs. See the Actions page for the full list and each action’s parameters.
