When defining a custom connector in Power Platform, which file format is used to describe the API operations and parameters?
Answer: OpenAPI (Swagger) 2.0 or 3.0
Custom connectors use OpenAPI (Swagger) 2.0 or 3.0 specifications to describe API operations, parameters, and responses.
A custom connector needs to call an API that returns paginated results. Which feature should you configure to automatically retrieve all pages?
Answer: Pagination policy
The pagination policy on a custom connector action automatically fetches subsequent pages by following next-page links or incrementing offsets.
You want to hide an internal API parameter from canvas app makers using your custom connector. What should you set on that parameter?
Answer: Visibility = internal
Setting a parameter's visibility to 'internal' hides it from the connector UI while still allowing it to be sent in requests.
Which authentication type should you choose for a custom connector that must support individual user logins via Azure AD without sharing a single service account?
Answer: OAuth 2.0
OAuth 2.0 delegates authentication to Azure AD so each user authenticates with their own identity rather than a shared credential.
A custom connector action returns a dynamic list of properties that vary per record. Which feature lets Power Automate show these properties dynamically in the designer?
Answer: Dynamic schema using x-ms-dynamic-schema
The x-ms-dynamic-schema extension calls a separate API endpoint to retrieve the actual response schema at design time.
What is the maximum size of the OpenAPI definition file that can be imported when creating a custom connector via the Power Platform portal?
Answer: 1 MB
The Power Platform custom connector import wizard accepts OpenAPI definition files up to 1 MB in size.
Which connector policy template would you use to add a static header value to every outbound request made by a custom connector?
Answer: Set HTTP header
The 'Set HTTP header' policy template lets you inject a fixed or expression-based header into every request the connector sends.
