Thank you so much Rahul. This has be very useful for my interview and you have great teaching skills.

The interviewer may also ask you about tokens, types of tokens (SWT, SAML, JWT). Besides, he may ask you to define the JSON structure format. It looks like a 'key value' structure type. And REST is not a protocol. It's is a software architectural style.

Great initiative. Thanks a ton

I have never seen such a clear explanation of any teaching video on api testing.. Plzz do more

Q-13: Can we use POST request instead of PUT to create a resource ? Your answer is Wrong. We can not. While post we do not require to specific about the index or on which resource we have to do a update operation where are in POST a new resource gets created with ID auto-generated. Requesting you to modify the answer on video 26:41

Hi Rahul. I have a test case where I have to take a screenshot after every click and store the screenshot in a Word document for documentation purposes. Please make a video on this.

please can you explain how to validate elements with Api.?

Not sure if i am correct but as per my understanding POST & PUT are different POST will create a new entry to db, where PUT will update existing entry from db with new fields or passed information.

@18.50 , I feel it's wrong , even a get call can also have a request body. A request which does not have a request body as called a head call and an api call which has payload also is called get call.

Savage 🔥

You forgot to say put is idempotent which is more important
