How To Add API gateway for your Java APIs Running on Azure Functions

A step by step guide with an example project

When you deploy your web apps or APIs on Azure Functions you can either expose them directly from the Azure function endpoint or you can serve through Azure APIM. Using APIM has several advantages such as routing to different apps based on the context path, implementing microservices, adding OAuth, caching layer, sharing your APIs through the Developer portal, etc.

In this post, we will see how to configure APIM for the Java APIs running on the Azure functions.
