What Are Rest API Methods?

We use certain HTTP methods to develop an application with Rest API. In this article, I will discuss these methods and the purposes for which they are used.

GET

This is the method the client should send to the server in order to retrieve data from the server.

GET /users

To fetch all users

GET /users/{id}

To fetch only the user with the specified id value

POST

This is the method the client should send to the server in order to add new data to the server.

POST /users/

To add a new user

PUT

This is the method the client should send to the server in order to change all data of a resource on the server.

PUT /users/

To edit user information 

PATCH

This is the method the client should send to the server in order to change just a specific part of a resource on the server.

PATCH /users/

To edit user information 

DELETE

This is the method the client should send to the server in order to delete data from the server.

DELETE /users/{id}

To delete a user

Besides the methods above, there are also a few others such as "COPY", "PURGE", "LINK", and "UNLINK", but they are not used very often.

Difference Between PUT and PATCH

PUT /users/1 

{     

"username": "urhoba",     

"email": "urhoba@urhoba.net" // New email address

}

PATCH /users/1

{

"email": "urhoba@urhoba.net" // New email address

}
