Postman Creating Your First API Request in Postman Estimated reading: 3 minutes 228 views Creating your first API request in Postman is an exciting milestone in the journey of API testing. It’s where you truly get hands-on with how APIs function. In this guide, I’ll show you how to send a basic API request and understand the response.Launch Postman and Create a New RequestClick the + icon in Postman to start a new tab. By default, it opens a blank request form. From here: Select the HTTP method (GET, POST,PUT,DELETE) Enter the request URL: https://mqa-banking-api.onrender.com/api/billing Click Send Creating A GET Request in Postman The base URL for all API requests:https://mqa-banking-api.onrender.com. Make sure to append the correct endpoint! Method URL DescriptionGET/api/billingGet all billing records (with populated person details)GET/api/billing:idGet a single billing record by its IDPOST/api/billingCreate a new billing recordPUT/api/billing:idUpdate an existing billing record by its IDDELETE/api/billing:idUpdate an existing billing record by its IDAnalyze the ResponseAfter sending your GET request, Postman provides a wealth of information to help you understand the server’s reply: Analyzing GET Response Request Status Code: Like 200 OK or 404 Not Found Response Time: Shows how long the server took to process and return the request, helping you gauge performance. Headers: Displays metadata sent by the server, including details like content type, cache policies, and authentication information Body: Contains the actual data returned from the server, typically formatted in JSON or XML, depending on the API.Sending a PUT RequestLet’s update some data using a PUT request! First, change the HTTP method at the top-left of Postman from GET to PUT. In the request area, click on the Body tab. Select the raw option, then set the format to JSON from the dropdown that appears next to it. Now, paste this JSON example below into the editor:PUT Request JSON Example{ "streetAddress": "1420 Elmo St", "city": "Miami", "state": "FL", "phoneNumber": "(512) 555-1234" } Double-check that your URL points to the correct resource you want to update. When you're ready, click the Send button.Postman will send your updated data to the server, and you’ll see the response right below including the status code, updated data, and any confirmation from the server.ConclusionBy creating your first API requests in Postman, you’ve taken an important step toward understanding how client-server interactions work. You’ve successfully sent both a GET and a PUT request — two essential building blocks for more advanced API testing. With these foundations in place, you’re ready to move beyond single requests and start organizing your work like a pro.Up next, we’ll dive into Organizing Tests with Collections and Variables to make your testing even more powerful and efficient!Tagged:Postman Postman - Previous Getting Started with Postman Next - Postman Organizing Tests with Collections and Variables
