**How to use PUT, DELETE, GET POST.**

In this article, we are going to learn how can we send different types of requests like GET, POST, PUT, and DELETE in the Postman. Postman is a popular API testing tool that is used to simplify the process of developing and testing APIs (Application Programming Interface). API acts as a bridge between two software applications which enables them to communicate and share data. Postman provides a simple Graphical User Interface for sending HTTP requests Like GET, POST, Put, Delete, and viewing their responses.

* **GET**: Used to retrieve information from the given server using a given URI. GET requests should only retrieve data and have no other effect on the data.
    
* **POST**: Sends data to a server to create or update a resource. The data is included in the body of the request. This may be a JSON payload, form data, or file.
    
* **PUT**: Replaces all current representations of the target resource with the uploaded content. It’s used to update existing resources.
    
* **DELETE**: Removes the specified resource from the server.
    

**How to send a GET request**

* **Step 1:** In Postman, from the collection add a new request and give a name get users. For this, we will be using the demo API to test the different types of requests.
    
* **Step 2:** Select the GET method from the dropdown.
    
* **Step 3:** Enter the URL of the API endpoint you wish to query.
    
* **Step 4:** Click ‘Send’. The server’s response will be displayed in the lower pane.

**How to send a POST request**

* **Step 1:** Create a new request as before.
    
* **Step 2:** Select POST from the method dropdown.
    
* **Step 3:** Enter the API endpoint URL.
    
* **Step 4:** Under the ‘Body’ tab, choose a format (e.g., form-data, x-www-form-urlencoded, raw (JSON, text, JavaScript, etc.))
    
* **Step 5:** Enter the data you wish to send and click ‘Send’.

**How to send PUT request**

PUT requests are used to update existing data on the server. Follow the same steps as the POST request, but select PUT as the method.

**Example:** Ensure the URL and body data are appropriate for updating data.

**How to send a DELETE request**

To delete data, use the same endpoints with an item ID.

**Example:** Send a DELETE request to [**https://jsonplaceholder.typicode.com/posts/1**](https://jsonplaceholder.typicode.com/posts/1) to delete the post with ID 1.
