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?
Select an answer to reveal the explanation.
Short Explanation
OpenAPI is the menu; the custom connector is the waiter who can place orders. You use it to turn Swagger operations into real actions you can call from Copilot Studio topics or flows. Knowledge sources only read documents; they don't execute API calls.
Full Explanation
Custom connectors wrap REST APIs for Power Platform. Once registered and authenticated, operations become callable from flows and agent actions/tools, with inputs/outputs mapped in topics.
The OpenAPI-as-PDF knowledge source option confuses documentation retrieval with invocation. The curl-in-Adaptive-Card option is not an integrated agent action pattern. The disable-HTTPS option is insecure and incorrect.
Exam tip: OpenAPI → custom connector → action in topic/flow; secure auth (OAuth, API key, etc.) on the connector.
