Must Watch Session
Before we dive into the technical details, I want to share something important with you. Learning APIs might feel overwhelming at first — new concepts, new tools, and sometimes even new programming languages. But here’s the truth: every expert you see today once started exactly where you are — at the beginning.
APIs are the backbone of modern applications. If you learn them well, you’re not just learning a skill — you’re unlocking opportunities. As a tester, automation engineer, or developer, mastering APIs makes you future-proof. It allows you to understand systems at a deeper level, build robust test automation, and speak the language of developers and architects with confidence.
Now, how do you succeed in this course?
1. Be consistent. Don’t rush. Watch one lesson, practice it, and repeat until it feels natural.
2. Hands-on learning. Every concept here is practical. Open your IDE, hit those APIs, see the responses. That’s how you’ll learn the fastest.
3. Don’t fear mistakes. When something doesn’t work — that’s not failure, that’s learning in progress. Debugging is where real growth happens.
4. Think beyond tasks. Ask yourself: Why is this API built this way? How can I test it better? What happens if I push it to its limits? That’s how you’ll think like an engineer, not just a tester.
5. Stay curious. The more you explore, the more doors you open — in automation, in interviews, in your career.
By the end of this course, you won’t just know how to automate APIs — you’ll have the confidence to solve real-world problems. And trust me, this confidence will set you apart in interviews, projects, and leadership discussions.
So, let’s start this journey together. Remember — it’s not about being perfect on day one, it’s about growing step by step. And every step you take here brings you closer to being the kind of engineer companies dream of hiring.
In this video, we break down the 5 most important HTTP methods used in API testing that every QA Engineer, Automation Tester, and SDET must understand. You will learn: • What GET request does in API testing • How POST is used to create data • Difference between PUT vs PATCH in real API scenarios • When to use DELETE request • Real examples used in API automation testing interviews These HTTP methods are the foundation of REST API testing, and they are commonly used with tools like Postman, Playwright, RestAssured, and automation frameworks.
Idempotency isn’t just a theory — it’s critical for reliable API automation. In this video, I’ll show you: What idempotency REALLY means Why your tests might be flawed How to validate APIs under retries & failures Real examples from production systems
If you've never used HEAD or OPTIONS in your API testing, you're leaving critical bugs undetected. These two HTTP methods are the secret weapons of every senior QA engineer and backend dev — and in this video, I'm going to show you exactly what they do, how they work under the hood, and why ignoring them is costing you time and catching you off guard in interviews.
This is Session - 04 of API Testing Course Series Most QA engineers and SDETs think they understand HTTP status codes… But in reality? They only know 200, 404, and 500 .
? In this video, we break down ALL HTTP Status Codes in a simple, practical way — specifically for API Testing, QA, and SDET roles.
