PUT and POST requests have lots of similarities certainly when making an HTTP request. PUT and POST requests have a strong connection with HTTP.  This article includes some major differences between PUT and POST requests.

What is PUT Method?

PUT is a request method supported by HTTP used by the World Wide Web, used to modify and update a resource.


PUT /blogs/{blog-id}


Here is an example of a PUT method:

  • HTTP PUT http://www.blog.com/users/123
  • HTTP PUT http://www.blog.com/users/123/accounts/567

What is POST Method?

POST method is used to create a resource, or overwrite it. The HTTP standard says that a POST request should be used when attempting to create a new resource representation. The POST request’s body contains the suggested state representation of the new resource to be added to the server.


POST /blogs


Here is an example of a POST method:

  • HTTP POST http://www.blog.com/users
  • HTTP POST http://www.blog.com/users/123/accounts

Difference between PUT and POST methods

This method is idempotent. In this method, if we send retry a request multiple times, that should be equivalent to a single request modification.This method is not idempotent. In this method, if we retry the request N times, we will end up having N resources with N different URIs created on the server.
The PUT method is used to modify a single resource.The POST method is used to add a child resource.
The PUT method is typically used for UPDATE operations.POST method is generally used for CREATE operations.
In the PUT method, the client decides which URI resource should have.In the POST method, the server decides which URI resource should have.
If you send the same request multiple times, the result will remain the same.If you send the same POST request more than one time, you will receive different results.
PUT works as specific.
POST work as abstract.

Advantages of the PUT Method

  • You can create a resource multiple times as you like.
  • Creating a resource with the PUT method is very easy.
  • It helps you to store the supplied entity under the supplied URI.
  • It can identify the entity enclosed with the request.

Advantages of the POST Method

  • You can keep the data private.
  • The POST method can be used to send binary as well as ASCII data.
  • It is a secure method as its requests do not remain in browser history.
  • It is very useful when you do not know the URL to keep any resource.
