WEBVTT 00:00.000 --> 00:04.000 API testing with Postman. 00:04.000 --> 00:07.000 Introduction to Postman. 00:07.000 --> 00:13.000 It is one of the most popular tools used to test and debug APIs. 00:15.000 --> 00:20.000 It provides a graphical interface, which means you don't have to write code to test APIs. 00:20.000 --> 00:26.000 You can simply click, select methods, add data, and send requests. 00:26.000 --> 00:34.000 Postman allows you to send HTTP requests to any API, such as Get, Post, Put, or Delete. 00:34.000 --> 00:42.000 Postman is a powerful tool for developers, testers, and students to understand and test APIs. 00:42.000 --> 00:51.000 For example, to check your products API, just open Postman, enter the URL, select Get, and click Send to see the response. 00:51.000 --> 00:58.000 Postman will immediately show the response from the server, making it easy to verify your API in seconds. 00:58.000 --> 01:10.000 In simple terms, Postman acts like a remote control for testing APIs, allowing you to test how an API behaves without building an entire application. 01:10.000 --> 01:14.000 When using Postman, setting up requests is a key task. 01:14.000 --> 01:23.000 It lets you choose different HTTP methods, such as Get, to retrieve data, Post, to send, or create data. 01:23.000 --> 01:29.000 Put, to update data, delete, to remove data. 01:29.000 --> 01:38.000 You can also add important headers like content type and authorization whenever needed, especially for APIs that require secure access. 01:38.000 --> 01:43.000 Postman makes it easy to send body data for Post or put requests. 01:43.000 --> 01:47.000 Like this Jason example with a name and price. 01:47.000 --> 01:56.000 Great for testing APIs for users or products, just set the URL, headers, and body in one simple Postman workspace. 01:56.000 --> 02:07.000 Postman helps you stay organized by placing your Get, Post, and Delete requests into a single API collection, so everything stays easy to manage. 02:07.000 --> 02:18.000 Postman also lets you create environments, which are sets of variables like, base URL, API keys, and tokens. 02:18.000 --> 02:29.000 Instead of typing the base URL repeatedly, you can save it as an environment variable and use it across requests, saving time and reducing errors. 02:29.000 --> 02:40.000 Collections and environments together help you build a more organized, scalable, and efficient workflow while learning or testing APIS. 02:40.000 --> 02:50.000 Postman also helps with debugging. If something goes wrong, you might encounter incorrect and point URLs, missing authentication. 02:51.000 --> 03:02.000 Wrong data format, payload errors, Postman allows you to fix and resend the request quickly, which helps you understand how APIs behave and what causes errors. 03:05.000 --> 03:13.000 It helps you understand the flow, check the system, correct issues, and find mistakes, all without writing code.
