This part of the use case scope demonstrates federation of API from different gateway providers. The sample provided here shows how you can integrate Microsoft Azure API Management with SAP Integration Suite, but it can be applied to any 3rd party API gateway that supports eventing with the CloudEvents standard and can provide an OpenAPI specification for it's resources.
-
Get an instance of Azure API Management
-
Activate Azure Event Grid
-
Dynamically expose Open API definitions in Azure API Management so that an SAP BTP webhook can callback and retrieve the API specification
- Make a minor adjustment to the set-url value so we can consume the event's subject directly:
https://management.azure.com/subscriptions/xxxx/resourceGroups/xxxx/providers/Microsoft.ApiManagement/service/xxxx" + context.Request.MatchedParameters.GetValueOrDefault("api-id","") + "?export=true&format=openapi&api-version=2021-01-01-preview")</set-url>
