How to go about creating a Copilot plugin through MS Copilot Studio for accessing 3rd party APIs?

The API's are available on the internal server.

Categories:

Assuming this is an HTTP endpoint that's avaialbe only on your "internal" network, you could build a custom connector for your API, which would connect to the API via the On Prem Data Gateway.

Once you have a working custom connector (test it first!) you could either load it directly as a plugin in Copilot Studio, or create a Power Automate flow that calls the connector, and load the flow as a plugin.

Some documentation:
