Testing APIs is a crucial part of ensuring that your applications work as expected. When dealing with Azure API Management (APIM), exporting APIs for testing can be a seamless experience, especially when you use tools like Postman.
To test an API from an APIM instance, the first step is to export the API definition. APIM allows you to export an API in a collection format, which can easily be imported into Postman.
To accomplish that you need to:
- Access to Azure Portal and go to your Azure API Management instance.
- On the API Management instande, choose the API you want to test from the APIs section.
- Click on the … (3 dots) associated with the API we want to export, and click on the Export option
- On the Export to panel, select the Export to Postman option.

Once imported, you can start sending requests to the API endpoints directly from Postman, making it easier to test various operations like GET, POST, PUT, and DELETE.
By using Postman in this way, developers can quickly check the functionality of an API without needing to manually code requests, which speeds up testing and troubleshooting.
Bonus Fact: You can even use this Postman collection in Azure Pipelines for automated API testing as part of your CI/CD process, ensuring that API functionality is validated every time new code is deployed.
