Postman UI & Creating First API Request

Postman UI & Creating First API Request

Well as you can see in above environment we have collections , history tab and work space so lets get familiar with it.

Work space

Work space is basically your area where all your things would be in. Multiple work spaces can be made so multiple teams can work on their work space only.

History Tab 

It will contain our request history so any request made by you is saved as history inside this tab.

Collections Tab

It will contain all the requests that you will make, so basically its a request container. Multiple collections can be made and you can put your requests in them accordingly.

Creating First API Request 

First we will create a work space so go to work space option in the middle of dashboard click on create new 

Now you would be having two options as type

1. Team (If you are selecting this than you can invite many people to work in same work space)
2. Personal  (If you want to work by yourself alone than choose this)

Fill up the form and click on create work space.

I have create work space as personal. Now I would like to create API request so I will click on new->request. Form will open fill out the fields and save your request inside collection by creating a collection in this form and then finally click on save in order to save request.

Now you will see request with GET method, I will be explaining these methods later but for now remember this.

1. GET is used to get the resource (when selecting)
2. PUT is used to update
3. POST to insert
4. DELETE to delete something

Now lets see how we will send an API request and how a response is seen against it. We will use a sample API using this website. It has many sample API's.

I am taking LIST USERS API so click on it and then click on (/api/users?page=2) . After clicking on this you can see the response on your browser.

Now in postman we have created request with the name First API Request, so using this we will check response of sample API we have taken by giving request. We will be using GET as we want to select response data.

Inside request URL put the link like this websitename/api. So we will put https://reqres.in/api/users?page=2 and then we click on send.

As you can see the response , means it's a working request. You will see in three formats pretty, raw and preview. Multiple reorientation of data can be seen like JSON , XML or whatever is present for the response. Or you can wrap line if very long line is coming in display. Status,time and size can also be seen where status is HTTP status and you can learn about more statuses. Time is the time taken to get the response. If you click on size more info can be seen.

Response can also be saved and searched.

Now new tab will open then again click on save example.

Now go to actual request tab and you will see your example as count 1. 

You are done with request but you can have a look to the diagram below to understand HTTP header and body concept.
