Using Postman for Testing RESTful APIs in ERP Systems

Learn how to use Postman for testing RESTful APIs during the development of ERP systems.

Why Testing APIs is Crucial

Postman is an essential tool for API development and testing. In this post, I’ll show how I used Postman to test the RESTful APIs developed for the Accounting ERP system.

Postman allowed me to test and debug APIs effectively:

1. Setting Up Postman Collections :

By testing early and often, I reduced post-deployment issues and ensured API reliability.

2. Testing Different HTTP Methods :

Use Postman to test all HTTP methods (GET, POST, PUT, DELETE).

POST /api/v1/orders
Body:
{
"customer_id": "12345",
"order_total": "250.00"
}

3. Automating Tests with Postman :

You can write tests in Postman using JavaScript to automate API testing.

pm.test("Status code is 200" , function () {
pm.response.to.have.status(200);
});

Summing It Up: Mastering API Testing with Postman

Postman is a powerful tool for API testing. Its ability to automate tests and log errors made the development process more efficient, helping us deploy error-free APIs.
