Import an OpenAPI specification
This article shows how to import an "OpenAPI specification" backend API residing at
https://conferenceapi.azurewebsites.net?format=json. This backend API is provided by Microsoft and hosted on Azure. The article also shows how to test the APIM API.
In this article, you learn how to:
- Import an OpenAPI specification using the Azure portal, Azure CLI, or Azure PowerShell
- Test the API in the Azure portal
API import limitations are documented in API import restrictions and known issues.
An API Management instance. If you don't already have one, complete the following quickstart: Create an Azure API Management instance.
If you prefer to run CLI reference commands locally, install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.
When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.
In the Azure portal, navigate to your API Management instance.
In the left menu, select APIs > + Add API.
Under Create from definition, select OpenAPI.
Enter API settings. You can set the values during creation or configure them later by going to the Settings tab. The settings are explained in the Import and publish your first API tutorial.
Test the new API in the portal
Operations can be called directly from the portal, which provides a convenient way for administrators to view and test the operations of an API.
Select the API you created in the previous step.
Select the Test tab.
Select an operation.
The page displays fields for query parameters and fields for the headers.
In the test console, API Management automatically populates an Ocp-Apim-Subscription-Key header, and configures the subscription key of the built-in all-access subscription. This key enables access to every API in the API Management instance. Optionally display the Ocp-Apim-Subscription-Key header by selecting the "eye" icon next to the HTTP Request.
Depending on the operation, enter query parameter values, header values, or a request body. Select Send.
When the test is successful, the backend responds with 200 OK and some data.
To debug an API, see Tutorial: Debug your APIs using request tracing.
Append other APIs
You can compose an API of APIs exposed by different services, including:
- The OpenAPI Specification
- A SOAP API
- A Web App hosted in Azure App Service
- Azure Function App
- Azure Logic Apps
- Azure Service Fabric
Append a different API to your existing API using the following steps.
When you import another API, the operations are appended to your current API.
Go to your Azure API Management instance in the Azure portal.
Select APIs on the Overview page or from the menu on the left.
Click ... next to the API that you want to append another API to.
Select Import from the drop-down menu.
Select a service from which to import an API.
