Import Azure Function into Azure API Management (APIM)

What Does Import Azure Function into APIM Mean?

Importing an Azure Function HTTP trigger into APIM allows APIM to act as a secure API gateway in front of your serverless backend.

Clients communicate with APIM, which forwards requests securely and applies policies like authentication, throttling, and monitoring.
