What is API testing and why is it important?

**API testing** involves verifying APIs (Application Programming Interfaces) directly—checking their functionality, reliability, performance, and security. Unlike UI testing, **api testing means** validating the logic layer. It’s crucial because it catches bugs early (Shift-Left) and ensures different software systems communicate correctly.

How is this different from a manual testing course?

While we cover **manual API testing** using Postman, this course focuses heavily on **API automation** and technical validation (JSON/XML). It is an advanced module often taken after or alongside a **manual testing course with placement**.

Do you cover API automation testing tools?

Yes, we extensively cover **Postman** (for both manual and automated testing) and **Newman** for CLI execution. We also introduce concepts relevant to **Rest Assured** and other **API automation testing tools**.

Can I learn API testing without coding?

Yes! Tools like **Postman** allow you to perform extensive testing with minimal coding. We teach you the necessary JavaScript snippets for validation, making it easy to **learn API testing** even if you are a beginner.

What are some API testing examples I will practice?

You will work on **REST API examples** like a Contact List app and an Employee Management system. You will verify **test api post request**, GET, PUT, DELETE methods, and Authorization headers using real **public api for testing**.

Do you provide placement support?

Absolutely. As a leading **software testing training** institute in Mumbai, we provide 100% placement support, including resume building (highlighting your **API test cases examples**), mock interviews, and referrals.

How do I test API endpoints in this course?

We use a hands-on approach. You will learn **how to test api** endpoints by sending requests, analyzing response codes (200 OK, 404 Not Found), validating JSON bodies, and checking response times.

Is this course strictly for Mumbai residents?

No, while our offline campus is in Thane/Mumbai, our **online API testing** classes are available globally. You get the same **manual testing course with placement** benefits and mentor support online.
