Connecting Existing Web APIs to APIM

One of the major configuration tasks for APIM is managing connected backend services. There are several ways to connect your existing web API as a backend to APIM. One way requires manually providing each endpoint with parameters. It’s a time-consuming process and only works for small APIs. The better option is to import API documentation directly: from Swagger or Web Application Description Language (WADL) and Web Services Description Language (WSDL) files. One more way of connecting is choosing an existing resource (e.g., Azure Functions, Logic Apps, or App Service) from an Azure subscription, which APIM connects automatically. In the previous code snippets, you executed the Azure CLI script to connect existing services by providing the OpenAPI documentation.
