***History Tab
Postman records history of your API request just like any other web browser automatically. As soon as you invoke a REST request, it is saved in the history and can be seen below the History Tab. It comes handy when you have to search for some particular request that you entered in the past without entering again.

***Collections
The concept of grouping requests is called Collections and each Collection is displayed under the Collection Tab. A collection in Postman can be imagined similar to a folder in your system. You create a folder, for example movies, and keep movies in it so that you know where all your movies are. Similarly in Postman we save the similar kind of requests under some collection name (that we define) and when we open any collection we get all the Requests under that heading.

***Import
Import option lets you import files of different format. Importing means choosing the files located in your system or through a link and running it through Postman.

***Interceptor
Recall we learnt that if you are installing the application from chrome then a separate interceptor is required for the proxy server. This interceptor is inbuilt in the native app. You can set proxy server here to capture all the API request that you send through your browser. A proxy server can be used to capture all the requests that you send through your browser or from your phone or any other system.

***Sync
Sync option is for synchronizing the API requests that you have sent on any machine to the Postman cloud. When you are working in Postman and making changes or sending requests, if you Sync is on, it will automatically be saved in your Postman’s cloud storage. This way you can have them saved and whenever you sign in on different machine to use Postman, they will automatically appear. This feature require you to sign in (If you did not during the installation part).

***Params
Params is the parameter option which allows us to write the parameters of the URL. The parameters are embedded into a URL and are very important to get the desired result. They also help us in getting efficient usage of the memory and bandwidth.

***Authorization
The authorization process verifies whether you have permission to access the data you want from the server. Not all data is available for everyone inside a company, so there lies the solution as Authorization. With the authorization, server first checks whether the data you are asking can be shown to you. If it can be, you get the desired response.

***Header
A header in the HTTP request or response is the additional information that is needed to be conveyed between the client-server. HTTP headers are mainly intended for the communication between the server and client in both directions.
