Welcome, everyone to another tech blog. In this article, we will look into a feature that will allow you to generate randomised data and effortlessly automate a series of API requests using Postman. Postman is an API platform for building and using APIs. Sounds intriguing, doesn’t it?

Why Automation?

Before we dive in further, let’s answer the crucial question: why do we need this? Imagine needing to populate your database with a multitude of user profiles for testing purposes. Instead of manually creating each one, envision triggering the creation of numerous random users with just a click. This feature in Postman comes to the rescue not only for user creation but also for various scenarios in your development journey.

Now, let’s waste no time and uncover the magic behind this feature.

Automate API Requests sending with Postman

Step 1: Dynamic variables

To start, let’s populate your API request body with dynamic, random values. Did you know that Postman provides a ready-to-use list of dynamic variables? You can find this list from here. These dynamic variables can be accessed using the $variableName notation. An example of the usage is given below.

Step 2: Execute multiple requests

With your request now dynamically powered, let’s move on to automation. To trigger Postman to send a series of dynamic requests, you’ll need to save it into a Postman collection.

Click on the relevant collection and choose Run.

You can now choose the API requests that you want to run and set the desired number of iterations. Bear in mind that the execution is sequential, not in parallel.

And There You Have It!

Voilà! Now you have successfully automated an API request sending using Postman.
