Testing Azure Website API Using Postman

Postman is a powerful tool for testing APIs, and it’s particularly useful when working with Azure Website APIs. Here’s a comprehensive guide on how to test your API using Postman, from setting up your environment to running various types of requests.

Setting Up Your Environment

  1. Install Postman: Download and install Postman from https://www.postman.com/.
  2. Create a New Request: Open Postman and create a new request by clicking the “New” button in the top left corner.
  3. Enter API Endpoint: In the “Request URL” field, enter the endpoint of your Azure Website API. For example: https://your-api-name.azurewebsites.net/api/your-resource
  4. Select HTTP Method: Choose the appropriate HTTP method (GET, POST, PUT, DELETE, etc.) for your API endpoint.

Example: Testing a GET Request

Request Headers

In the “Headers” tab, you can define request headers. For example, to set the Content-Type header for a JSON request:

Content-Type: application/json

Request Body

If your GET request requires a body (which is less common), you can add the data within the “Body” tab. Select the “raw” option and choose JSON as the format.

Sending the Request

Click the “Send” button to execute your request.

Example: Testing a POST Request

Request Body

Use the “Body” tab to add data to your POST request. For JSON data, enter the following in the “raw” body:

{
  "name": "John Doe",
  "email": "john.doe@example.com"
}

Response Handling

Postman will display the response from your API in the “Response” tab. This includes:

  • Status Code: Check if the request was successful (200 OK), or if there were errors (400 Bad Request, 500 Internal Server Error, etc.).
  • Response Headers: View the headers returned by the API.
  • Response Body: Examine the data returned by the API in the specified format (JSON, XML, etc.).

Example: Testing Authentication

Many Azure Website APIs require authentication. You can configure authorization in Postman using the “Authorization” tab:

  • OAuth 2.0: For APIs using OAuth 2.0 authentication.
  • Basic Auth: For basic authentication with username and password.
  • Bearer Token: For APIs using API keys or JWTs.

For example, to authorize with a Bearer Token:

  1. Select “Bearer Token” as the type.
  2. Enter your token in the “Token” field.

Running Tests and Assertions

Postman allows you to create automated tests for your API requests using the Tests tab:

pm.test("Status code is 200", function () {
  pm.response.to.have.status(200);
});


pm.test("Response body has 'success' property", function () {
  pm.response.to.have.jsonBody("success");
});

This code snippet checks for a successful status code (200) and verifies that the response body contains a property named “success”.

Environment Variables

Postman supports environment variables, allowing you to easily manage API keys, endpoints, and other sensitive information. You can create and manage environments from the “Environments” tab.

Collections

Postman collections are a way to organize your API requests into groups. They help you structure your tests and make them more manageable. You can create and edit collections by clicking the “Collections” button.

Documentation and Sharing

You can generate documentation for your API tests directly within Postman using the “Docs” feature. This creates a comprehensive overview of your API endpoints, request parameters, and expected responses. Additionally, you can share your collections and environments with your team through Postman’s collaboration features.

By following this guide, you can master testing Azure Website APIs with Postman, enhancing your API development and ensuring the quality of your applications.
