What is cURL?

cURL is a computer software project that provides a library as well as a command-line utility for transmitting data across several network protocols. The name is an abbreviation for “Client URL.”

cURL is a command-line utility for retrieving and delivering data, including files, through URL syntax. Because cURL is based on libcurl, it supports every protocol that libcurl supports.

When a secure protocol, such as HTTPS, is selected, cURL conducts SSL certificate checking by default. When cURL connects to a distant server over HTTPS, it obtains the remote server certificate, then checks the authenticity of the remote server against its CA certificate database to guarantee the remote server is who it claims to be.

What is Postman?

Postman is an API platform that allows you to create and use APIs. Postman streamlines collaboration and simplifies each phase of the API lifecycle, allowing you to design better APIs quicker.

Postman describes itself as “the only full API development environment.” Postman is the only full API development environment, with roughly 5 million developers and over 100,000 businesses globally using it.

Postman is a platform for testing APIs. cURL is a command-line utility that allows you to transmit data over URLs. To do the same operations with REST APIs, we may use Postman as a GUI (graphical user interface) and cURL as a CLI (command-line interface).

Difference between cURL and Postman?

cURL is defined as a “Command Line Tool and Library for Transferring Data With URLs” by its creators. To transmit data, it is used in command lines or scripts. It is also found in automobiles, television sets, routers, printers, audio equipment, mobile phones, and tablets, and serves as the internet transfer backbone for thousands of software programs that influence billions of people every day.

Postman, on the other hand, is described as “the only comprehensive API development environment.” Postman is the only full API development environment, with roughly five million developers and over 100,000 businesses globally using it.

cURL belongs to the “File Transfer” category, whereas Postman belongs to the “API Tools” category.

Postman has a decent user interface that makes it simple to add/remove parameters, and modifying things is more versatile. Postman also allows users to save requests and other data, whereas cURL does not. In a nutshell, Postman enables a more contemporary, easier approach

Postman can assist in making cURL more user-friendly. We accomplish this in two ways.

  • A more user-friendly method for creating cURL commands Using the code snippet generator, you may create a request in Postman and convert it to cURL.
  • cURL instructions are executed in a more user-friendly manner. You may perform a cURL request by importing it into Postman.

Using the code snippet generator, you may create a request in Postman and convert it to cURL. cURL instructions are executed in a more user-friendly manner. You may perform a cURL request by importing it into Postman.

Curl for API Testing

Curl is a cross-platform command-line program that allows you to interface with numerous servers using URL syntax and a range of different protocols. cURL is capable of automating file transfers or a series of similar actions. It is, for example, a useful tool for modeling client activities with an API.

Let’s take a brief look at how to test REST APIs with curl. Curl is a data transmission command-line utility that supports roughly 22 protocols, including HTTP. This combination makes it an excellent specific tool for testing virtually any REST service.

Optional Command-line Parameters

Curl has more than 200 command-line parameters. A REST request can be executed without parameters or with one or more arguments to accompany the URL request in the command.

Postman for API Testing

With a beautiful user interface, Postman is meant to check requests from the client to the server and obtain a response from the back-end. According to the tool’s creators, “Postman is a robust suite of API testing tools that has become a necessity for many developers.” We build fantastic tools to assist you in creating attractive APIs and increasing developer productivity.

Postman is used by over a million developers worldwide, and the number is continually rising. We want to create further solutions in order to give developers the most powerful solution for designing and testing APIs.” Postman comes with a graphical user interface for creating and verifying requests.
