HTTP Request Methods For Beginners

As Software Engineers, at some point in our careers we are either going to be creating or consuming external APIs. In this post, I broke down the common HTTP Request Methods that exist today.

What is HTTP?

HTTP (full name Hypertext Transfer Protocol) is a protocol designed for clients applications to communicate with servers. Usually, a client sends the request and a server receives that, performs some action and sends a response back to the client. The response usually contains status information about the request and could contain other additional information.

Other protocols exist today but HTTP is used a lot on the web. Imagine visiting a URL identifying an HTML resource. A call will be made from the browser to the server to fetch that resource and render it on the browser for you to read. See below:

Now that we’ve been introduced to HTTP, let’s take a look at HTTP Methods.

HTTP Methods

When making HTTP requests, the client has to specify the particular action to be performed on a given resource. HTTP has a set of request methods for this purpose. Let’s meet them below:



You can use the GET request to retrieve data about a resource. It could be a single data or a collection of data.

Calling a GET on the endpoint v1.0/requests would return a list of requests. Calling a GET on the endpoint v1.0/requests/{id} would return a request resource with the specified id.

An example of a scenario where a GET request would be used is when a client wants to fetch all pending orders belonging to a user from a backend server.


You can use the POST request to submit an entity to the specified resource. POST requests are commonly used when trying to create a nw record. This usually changes the state of the server.

Calling a POST on the endpoint v1.0/orders would create a new order entry on the backend.

An example of a scenario where a POST request would be used is when a user wants to register on a web application. They enter their details through a form and their records get created on the backend server. The request to create that record is a POST request.


You can use the PUT request to update a particular record with the new payload. A scenario for using a PUT request is when we have an order record and we would like to update the details of that particular order at once (e.g. change order status from in-transit to delivered).

Calling a PUT on the endpoint v1.0/orders/{id} with a valid payload will update the order record bearing that particular id with the new payload.


A PATCH request can be used to partially update or modify a resource. Unlike PUT, PATCH requests are not safe or idempotent.

An instance when PATCH can be used is when updating just one field in a record. In this case, since the entire record shouldn’t be updated because sending the full payload requires unnecessary bandwidth a PATCH request could suffice.


A DELETE request can be used to delete a specified resource. Calling a delete on the endpoint v1.0/orders/{id} will delete an order having that particular identifier if the order exists.
