Question

Your LOB team exposes an internal REST API with an OpenAPI (Swagger) definition. You need Copilot Studio to call specific operations as tools. What is the recommended low-code approach?

Accepted Answer

Create a Power Platform custom connector from the OpenAPI definition, configure authentication, add the connector operations as actions available to the agent/flow, and map inputs/outputs in topics. — OpenAPI is the menu; the custom connector is the waiter who can place orders. Knowledge sources read documents — they do not execute API operations.

Answer

Store the OpenAPI file only as a knowledge source PDF so generative answers "call" the API by reading the spec text.

Answer

Paste sample curl commands into Adaptive Card Text Blocks and ask users to run them on their machines.

Answer

Disable HTTPS on the API so Copilot Studio can call it without a connector.
