I understand in postman we use test cases like status codes and response time to ensure API does not break but what is the necessity to validate the response body.
var schema
var jsonData = JSON.parse(responseBody);
tests["Verify that the Schema is Valid"] = tv4.validate(jsonData, schema);
To answer your question, Why is JSON Schema Validation required?
We monitor API responses and ensure that the format that we are getting is the same as the expected one.
We get alerts whenever there is any breaking change in the JSON response.
We use JSON Schema to construct a model of API response and it makes easier to validate
that API is returning the valid data.

Is there a way in Postman to obtain automatically, if an endpoint returns an HTTP 401, a new API key for that user by calling the login endpoint? In this situation Postman loads the result and store the API key in a variable in the specific Environment.
The test tab in Postman allows you to write some JS code that retrieves the response data and allows you to act accordingly.
Then the postman API allows you to set the next request in the collection runner or newman, so you can just call the login request properly.
Basically something like this:
const jsonData = pm.response.json()
if (pm.response.code === 401) {
pm.setNextRequest('login')
}
Here is some further reading about scripting in postman.
Am am currently using Postman to test the api results. I have been following the apostrophe headless docs, since am completely new to this. so what i need is to submit a post request in Postman to add a piece and its fields from REST api. I have got the bearer token and login was success. but when i insert a piece with body as JSON schema. am getting a error message.
May be the way am doing is wrong. so can one one help me in Making a post request to add piece and fields through POSTMAN atleast?
I did not understand the question quite right. You should add some of your inputs, error message, url, pics and etc. to clarify the problem.
However, if you need an example to how to use postman to make a POST request, it's like this:
Select the POST method and insert the API URL (The landing url for POST method not the view and etc.)
Go to headers Tab and add the Authorization token to header
Select the Body tab; Then raw type and finally JSON type. Now insert the Json body and click Send.
You can see the result of webservice call on the top of response window. If it returned 200, everything was OK.

I would like to measure the POST and GET endpoint performance by using POSTMAN collection - run feature.
ideally, i wanted to use same POST endpoint, but the json data is different at each iteration.
Possible to do that in POSTMAN?
In the postman api you can write scripted tests where you can change the data between each test. It can be the same request with different data.
Also you can use dynamic variables in the sandbox
I hope this helps
We are trying to get check-boxed items list from front-end as a request query to a GraphQL endpoint and with that request trigger one function to manipulate the selected items in Django to return a response.
This is for a web application to process files when get query from front-end to a GraphQL endpoint. And upload it to a s3 bucket and return a link to file as response. Using DRF we could achieve it with request.POST and getting the items with a object filter.
With GraphQL how to achieve it? Do we need to use mutation or just a query is enough to trigger a function at back-end.
Receive the query request with selected items list, trigger a function to manipulate the items got through query and return a response. How can we implement this with GraphQL and Django?
We figured it out, get the check boxed items list as an argument in GraphQL as graphene.List(graphene.Int) and process that argument in mutate function, return response.
