**Introduction:**
Postman is an application that permits us to test APIs employing a graphical user interface. Some of Postman's benefits include the collection characteristic and the opportunity to complete various testing environments. It is a user-friendly device that allows us to optimize our time when conducting tests. Further, it destroys the demand to complete any HTTP client network code. Instead, we complete collections of test cases and let Postman link with the API. Thus numerous specialists are accepting the help of **[Postman Online Training](https://www.cromacampus.com/courses/postman-online-training-in-india/)** to learn its fundamentals. This is because almost all of the quality that a developer would need is inside this application. This tool can change the API into code for languages like JavaScript and Python.

**Top 5 characteristics of Postman:**
Here are the 5 Postman features everyone should know that can give a more useful insight into this unique tool-
**1. The Postman API-** The Postman API permits you to programmatically access data stored in your Postman account. Also complete all the classic CRUD operations on your collections, conditions, mocks, and more. This is a fairly new feature that permits you to start a collection run with an API call to the webhook URL. Requests sent to the webhook URL can also include your custom payload, which can be accessed in the group.
**2. Postman Echo-** Postman Echo is a benefit that we built as a bit of a sanity checker and understanding tool. It permits you to test your REST clients and make model API calls. As the name suggests, the API “echoes” back what you transmitted to it, which is a wonderful way to see what you’re sending to a server without having to analyze backend logs. 
**3. Postman Visulazier-** Postman supplies a programmable way to visually represent your proposal reactions. Utilizing HTML, CSS, and JavaScript, we can add visualization for the reaction body right into Postman. Further utilize the Visualizer to deliver your response data in ways that enable you to make sense of it. 
**4. Built-in Libraries-** Postman has a suite of outward libraries open to employing in the Pre-request and Test script tabs. These libraries make developers’ lives much easier by delivering functionality not necessarily created in JavaScript. 
**5. Workflow Control-** In a collection with numerous recommendations, often it creates purpose for the demands to be run in sequential order. Other times, it’s practical to skip or repeat certain demands.

**Necessity of Postman:**
Postman has a huge user base and has evolved as a very famous tool because of the causes listed below −

  appropriate for use by teams with any   capability.
• It can be accustomed very efficiently by just downloading it.
• Postman can be accessed very smoothly by logging into your 
  account after induction on the    widget.
• It permits easy supervision of test suites with the benefit of 
  collections. Additionally users   can create a collection of API 
  calls that can have varied demands and subfolders.
• Postman is able of building numerous API calls like SOAP, REST, 
  and HTTP.
• It can be employed for test development by the addition of 
  checkpoints to HTTP reply codes and   other parameters.
• Postman integrate with ongoing integration and either continuous 
  delivery or deployment (CI/CD)   pipeline.
• It integrates with Newman or Collection Runner which permits 
  conducting tests in many   iterations. Thus we can detour 
  reprised tests.
• Postman has great community backing.
• The Postman console permits debugging trial steps.
• With Postman, we can complete more than one environment. Thus, a 
  single collection aids diverse   designs.
• Postman gives the option to import/export Environments and 
  Collections, allowing comfortable   sharing of files.

**Conclusion:**
Thus, due to its user-friendly UI, Postman contends to be one of the most prominent software testing tools. Hence its usability is comprehensive. Additionally, multiple organizations are employing proficient developers who are experts in using this module.
