I was reading through the documentation for the SharePoint API in PowerAutomate and I noticed that the Returns category of certain actions is undefined in the docs, however in the PowerAutomate page I can see the possible outputs for this particular trigger.
I have searched a bit and found that PowerAutomate uses OpenAPI to define the inputs/outputs, so I was wondering where I could find these OpenAPI definitions for the functions and triggers used by Microsoft.
Thank you for your time
Most of the Microsoft connectors are from Graph API.
If you want the OpenAPI definition of those then you can find them @ https://github.com/microsoftgraph/msgraph-sdk-powershell/tree/dev/openApiDocs/v1.0
And one other link to third-party connectors: https://github.com/microsoft/PowerPlatformConnectors
