What are Postman JavaScript Objects?

Postman JavaScript objects are a set of built-in objects and functions that can be used within scripts in Postman collections, requests, and environments. These objects offer a wide range of capabilities, including data manipulation, workflow automation, and integration with external services.

Step 1: Environment Variables (pm.environment)

This approach allows you to access and modify environment variables. For example, you can set a new environment variable like this:

pm.environment.set("token", "your_access_token");

Step 2: Global Variables (pm.globals):

Global variables are accessible across requests and collections. You can set a global variable as follows:

pm.globals.set("apiKey", "your_api_key");

Step 3: Request and Response Manipulation (pm.request and pm.response):

These objects enable you to manipulate request and response data. For instance, you can access request headers like this:

const headers = pm.request.headers;

Step 4: Data Manipulation (JavaScript Functions):

Postman provides JavaScript functions like pm.iterationData, pm.variables, etc., for data manipulation tasks within scripts.

Managing API data and workflows efficiently is very important for developers. Postman, a popular API development environment, provides powerful tools to streamline this process. One such tool is Postman JavaScript objects, which allow you to manipulate data and automate workflows effectively. In this article, we’ll learn how to use Postman JavaScript objects to manage API data and workflows seamlessly.
