Postman Navigation

After downloading and installing Postman in our system, we will now discuss the user interface of Postman to learn about the features and terminologies that Postman offers.

We can split the postman navigation into four UI structures, as shown in the image below.

Postman Navigation
  1. Header bar
  2. Sidebar
  3. Builder section
  4. Response section

1. Header bar

Header bar contains the following options-

New

Postman Navigation

The new option is used for the following tasks

Request

It is used to create a new request, where you can create and save requests by entering the request name and can use it in the future.

Postman Navigation

Collection

It saves your requests in the form of a collection for reusing and sharing.

Postman Navigation

Environment

Environments are variables with key-values. Every variable name represents its key. So if we reference the name of the variable, it enables us to access its corresponding value. So it basically saves the values you frequently use in an environment.

Postman Navigation

The new button also provides some advanced features like

Documentation - to create documentation for API,

Mock server- to create in-development APIs,

Monitor- to test API performance,

API - for managing all aspects of APIs, including design, development, and testing.

  • Import

You may use the Import option for importing files in different formats into the software. As seen in the image below, you can import Postman collection and Environment files from any location and can run it through postman.

Postman Navigation
  • Runner

This option helps to directly run the loaded collections in the Postman.

Postman Navigation
  • Open new icon

This option is used to open a new Tab, a new Postman window, and a new Runner window.

Postman Navigation
  • My Workspace

This option helps you to view, manage, and create personal as well as team workspaces. Collections, monitors, environments, and mocks are components of the workspace.

Postman Navigation
  • Invite

This is used to invite other users into your team to collaborate with them for team workspace. As seen in the image below, this can be done by entering the email address or uploading the list of people to invite them.

Postman Navigation
  • Sync icon

This option is used to synchronize the API requests that you send from other devices and updates your postman account status.

Postman Navigation
  • Interceptor icon

The interceptor option is a proxy server, used to capture all the requests that you send through browser or phone or from any other device.

  • Settings icon
Postman Navigation
  • Notification icon

It shows all the notification of the Postman app.

2. Sidebar

Postman Navigation
  • History
    The history option is situated below the filter section of the app. The History tab automatically keeps a record of all your API requests, just like any other browser. It keeps handy all your past searches.
  • Collections
    The collection is the group of related requests which are displayed under the collection tab. In the collection tab, you can also create a new collection, as shown in the picture below. There is also a Trash section from where you can recover your lost or deleted collections.
Postman Navigation
  • APIs

All the APIs are listed in this section. New API can also be created from this tab.

Postman Navigation

3. Builder or Request section

Postman Navigation
  • Untitled Request

'Untitled request' is basically the default request title you are working on. The title depends on the type of request method you are working on, as shown in the image below.

Postman Navigation
  • HTTP request
Postman Navigation

This option opens a drop-down list of all the HTTP request methods, as shown in the image like GET, DELETE, PATCH, OPTIONS, LINK, POST, COPY, UNLOCK, PURGE, etc. In general, we mostly use POST and GET. We will discuss these requests in later chapters.

  • Request URL or Endpoint

This URL option is like any other browser URL. In this, we mention the link to where the API will communicate with.

Postman Navigation
  • Params

This option is used to write the parameters of the request. These parameters include key values and descriptions.

Postman Navigation
  • Authorization

The authorization process is required to access the APIs. This process verifies whether you have permission from the server to access the data you want. We will discuss this as a complete chapter later on.

Postman Navigation
  • Headers

An HTTP request header is the additional data that is required to send along with the request. This header information is required for proper two-direction communication between the client and the server.

  • Body

It let you specify the data type that you need to send with a request. There are various types of body data that you can send to match your API.

Postman Navigation
  • Pre-request script

These are written in JavaScript, and as the name suggests, these are executed before sending the request. Generally, these scripts are for setting the environment and ensuring that the request is running in the right environment.

Postman Navigation
  • Test scripts

It is executed during the request. It is also written in JavaScript. This helps you to ensure that API works as intended. Testing is important as it sets up checkpoints to verify whether the response status is ok and retrieved data is as expected.

Postman Navigation

4. Response section

The API responses which are sent back from the server are shown in the response window. These are generated after you send an API request to the server. As we have not sent any request, so there is no response in our case.
