@Bhargav Pasarla Thanks for reaching out. When you import a function app into APIM, APIM uses the Azure Resource Manager API to discover the function app and its associated functions. https://management.azure.com//subscriptions/xxxxxxx/resourceGroups/xxx/providers/Microsoft.Web/sites/xxxxxx?api-version=2016-08-01
It creates an API operation for each function in the function app. APIM maps the API operations to APIs based on the function app's URL path. By default, APIM uses the function app's name as the API name and the function's name as the API operation name.
Do let me know if you have any queries.
