Introduction
More than 500,000 businesses and 20 million developers utilise Postman. It is the top API platform in the world for creating and managing APIs. It is one of the most well-liked software testing tools to test APIs. Developers may quickly create, test, share, and document APIs with the aid of this tool.
You can use your app's APIs and libraries from Postman's developer resources. On GitHub, Postman's open-source projects are available for usage and contribution. This article gives insight into developer resources that enable you to interact with the Postman community and incorporate postman into your workflow.
Postman API
🚀 Endpoints: Postman API
🚀 Use: Send requests to access the Postman data you have.
Through the Postman API, you can perform the following activities:
🔥 Add and run monitors.
🔥 Update environments.
🔥 Add and run new collections.
🔥 Update existing collections.
We can now access data kept in our Postman account. Additionally, we may incorporate Postman with our CI/CD workflow by combining the Postman API with Newman.
The API's collection can be forked to get started. To use the Postman API, you must have an API key.
Generating Postman API Key
🧩 Step 1: Click on the Postman API Keys page. In the top-right corner> Settings, choose your avatar.
🧩 Step 2: Select the Postman API keys. You will be asked to create a key if you don't already have one.
🧩 Step 3: Choose to Create API Key.
🧩 Step 4: Select Generate API Key after entering a name for your key.
🧩 Step 5: Then close after copying your key.
Echo API
🚀 Endpoints: GET, POST, PUT
🚀 Use: Learn and practice Postman using the Echo API.
Through the API, you can perform the following activities:
🔥 To test requests in Postman.
🔥 Responds with a JSON response.
🔥 It is used by many Postman learning resources in Learning Centers.
🔥 To use Postman without connecting to a "real" API.
The JSON response contains all the information from your request and any additional data elements. It offers a simple way to send a request without worrying about authentication or request setup.
Using Echo API
🧩 Step 1: Open a new request in Postman and type the following URL into the URL field to test the Echo API:
postman-echo.com/get
🧩 Step 2: Select Send after choosing the GET method.
The Echo API's JSON object will include information from the request.
Collection SDK
The features of the collection SDK in the Postman are as follows:
🔥 It is a Node.js package.
🔥 It enables you to interact with Postman Collections.
🔥 Dynamically incorporate collections into your pipeline.
You can create and modify collections using the Collection SDK. By exporting them in a format, you can then include them with other tools like:
Postman.
Newman.
The command-line collection runner for Postman.
Using the Collection SDK
It is an open-source project. It summarizes the SDK's available objects and methods and introduces the relevant ideas.
The Postman Collection Schema's data structures are available through the Collection SDK's interface. The SDK methods can define request detail, variables, authentication, and other things and construct and edit collection elements.
Install the Collection SDK from the project repository, use the techniques to build collections that work for your development or testing project, and then get started. You can create issues for any concerns or feature requests, fork the project, and contribute.
Postman Runtime Library
The Postman Runtime library enables sending requests and running collections in Newman, Postman's command-line collection runner.
Using the Postman Runtime Library
It is an open-source Node.js project. In your projects for developing and testing APIs, you can utilise them for low-level setup instead of sending requests.
The library is available for installation through npm. The Runtime library can be used in conjunction with the Collection SDK, as seen in the following example code:
runtime = require('postman-runtime');
var runner = new runtime.Runner();
//The Collection object was constructed using the Collection SDK
var collection = new sdk.Collection();
runner.run(collection, {
data: [],
timeout: {
request: 30000,
script: 5000
},
iterationCount: 1,
//other options...
},
function (err, run) {
//The Callbacks to execute as the collection runs
run.start(callbacks);
});
Code Generator Library
In Postman, you may create client code for your API collections. With the Collection SDK, Postman's Node.js code generator module transforms a request into client code for your target language.
The Collection SDK Request object is passed to the code generator, which converts it into code for the identical request to be made in a client app using the chosen language and framework.
We can download the code generation library through npm or clone its repository.
Postman Collection Conversion
We can convert several API formats into Postman Collections. You can convert it with the following schema definitions:
🔥 OpenAPI.
🔥 Swagger
🔥 RAML
🔥 GraphQL.
The app allows you to import Postman Collections and use them with other Postman tools like Newman, the command-line collection runner.
Frequently Asked Questions
What is Postman?
It is a very well-liked API testing tool that helps create, share, and test an API. For skilled testers, it offers a command-line utility and a GUI interface to the API.
What is a collection?
In Postman, a collection is used to group related requests. It aids in organising the requests into folders in a systematic manner.
What is an API?
An API is a collection of protocols and resources for developing software applications. APIs define how two software programs should link with one another.
