Step-by-Step Guide to Import an API into Azure API Management

To import an API into Azure API Management (APIM), you can use the Azure portal, Azure CLI, or Azure PowerShell. Below is a step-by-step explanation of how to import an API into APIM using the Azure portal, along with an example.

Step-by-Step Guide to Import an API into Azure API Management

Prerequisites:

1. Azure Account: You need an active Azure subscription.
2. API Management Service: You should have an API Management instance created.
3. API Definition: You need the API definition file (e.g., OpenAPI/Swagger, WSDL, etc.).

Steps:

1. Log in to Azure Portal:
   • Go to the Azure Portal.
2. Navigate to API Management Service:
   • In the Azure portal, search for “API Management services” in the search bar and select your API Management instance.
3. Import API:
   • In the left-hand menu, under the “APIs” section, click on “APIs”.
   • Click on the “+ Add API” button.
4. Choose the Import Option:
   • You will see several options to create an API. Choose “OpenAPI” (or the appropriate option based on your API definition format).
   • In the “Create from OpenAPI specification” section, you can either:
     • Upload a file: If you have the OpenAPI/Swagger file locally.
     • Enter a URL: If the OpenAPI/Swagger file is hosted online.
5. Configure API Settings:
   • Display name: Enter a name for your API (e.g., “PetStore API”).
   • Name: This will be auto-filled but can be modified.
   • API URL suffix: This is the suffix that will be appended to the base URL of your API Management service (e.g., “petstore”).
   • Version: (Optional) If your API is versioned, you can specify the version here.
   • Products: (Optional) You can associate the API with a product, which is a way to group APIs and manage access.
6. Review and Create:
   • Review the settings and click on “Create”.
7. Test the API:
   • Once the API is imported, you can test it using the “Test” tab in the API Management service.
   • You can also configure policies, set up authentication, and manage other settings as needed.

Example: Importing a PetStore API

Let’s assume you have a PetStore API defined in an OpenAPI/Swagger file (petstore.json).

1. Upload the OpenAPI File:
   • In the “Create from OpenAPI specification” section, select “Upload a file”.
   • Click on the folder icon and upload the petstore.json file.
2. Configure API Settings:
   • Display name: “PetStore API”
   • Name: “petstore”
   • API URL suffix: “petstore”
   • Products: (Optional) Select “Starter” or “Unlimited” if you want to associate the API with a product.
3. Create the API:
   • Click on “Create”.
4. Test the API:
   • Go to the “Test” tab and select an operation (e.g., GET /pets).
   • Click on “Send” to test the API and see the response.
