Mocking Custom Responses with Azure API Management – Simple Mock Response

Mocking API responses is often essential to support the quality assurance team and enable development testing activities. Azure API Management (APIM) provides a comprehensive solution for this, allowing us to mock responses with specific status codes and even craft custom response messages. This is achieved by leveraging custom policies within APIM, enabling greater flexibility and control over simulated API behavior.

This article is the first of a three-part series. In this article, I will cover simple mock responses, while the rest in the series will discuss on crafting custom response messages. Below are the different parts of this article series.

Simple mock responses

Let's assume we need to send a 200 OK response to an API that has no backend service connected. Here are the steps you need to follow:

Navigate to the API operation and select "Add Policy" in the Inbound Processing section.

 

Select the "Mock responses" policy.

Next, select the desired response. In this case, choose "200 OK."

That's it! When you navigate to the test console and execute the API, you will receive a 200 OK response, even though no backend service is configured.
