How to Test ASP.NET Core Web API Using Postman

1. Install Postman: If you haven’t already, download and install Postman from the official website (https://www.postman.com/downloads/).
2. Launch Postman: Open the Postman application on your computer.
3. Import your API Documentation: If you have an OpenAPI specification (formerly known as Swagger specification) for your API, you can import it into Postman. Click on “Import” in the Postman application and choose the option to import from a file. Select your OpenAPI specification file (usually in JSON or YAML format) and import it into Postman.
4. Explore the API Documentation: Once imported, you can explore your API documentation within Postman. It will list all the available endpoints, request methods (GET, POST, PUT, DELETE, etc.), request parameters, headers, and response structures.
5. Send Requests: To test your API, select an endpoint from the documentation, choose the appropriate HTTP method, and click the “Send” button. Postman will send the request to the specified URL with the provided parameters.
6. Inspect the Response: Postman will display the response received from the API. You can examine the status code, response headers, and the response body. You can also use Postman’s built-in tools to format and validate the response data.
