Sending Array in form-data with Postman

API testing sometimes requires sending an Array in form-data format. In this article, we will discuss how to achieve this using Postman.

Why send an Array in form-data?

When it comes to API testing, sending an Array in form-data is necessary due to the convenient data format it provides. There are two main reasons for sending an Array in form-data:

HTTP Protocol Specification

The HTTP protocol defines form-data as a way to transfer data in the request body. This format allows associating multiple values with a single key, enabling the server to interpret the values as an array.

Server-side Implementation

The server-side implementation also plays a role in determining how an Array in form-data is handled. Most web application frameworks support passing arrays in form-data, ensuring the data is interpreted correctly on the server side.

Sending Array with Postman

Postman is a popular tool for API development and testing. Here's how you can send an Array in form-data using Postman:
