The raw view is a large text area with the response body. It can indicate whether your response is minified.
Extracting data from responses and chaining requests
If your API endpoint returns an image, Postman will detect and render it automatically. You can then view it using the appropriate viewer. Headers are displayed as key-value pairs under the Headers tab. Hovering over the header name can give you a description of the header according to the HTTP spec. Postman automatically calculates the time it took for the response to arrive from the server. This is useful for some preliminary testing for performance. Cookies sent by the server are visible in a dedicated tab.
If you're working in the Postman Chrome app, you can use the Interceptor extension to help manage cookies. You can also see the results of the tests that were run against the request.

In this post, we will see parsing JSON response and extracting values.
Mainly we will see parsing a JSON object in this post. It is easy for humans to read and write. It is easy for machines to parse and generate.

Now for assertion, we need to extract values of different keys and assert with expected values. Before extracting values from JSON response, we need to parse it first. We can parse response into JSON using below statement Note:- You will not get nested keys like checkin, checkout. We need to use dot operator when it is constant and square bracket when key is not constant so that it will evaluate the value of key first before searching for the value in JSON.
