Know More about 202 Status Code!

This Hyper Text Transfer Protocol, also known as HTTP, has accepted 202 response status codes indicating that “the request has been accepted for processing, but the processing has not been completed.” Moreover, it means processing may not have been started yet & the request might or might not eventually be acted upon whenever the processing actually takes place. Apart from all that, 202 is noncommittal, meaning that there is no way for the HTTP to send any response indicating the outcome regarding the request processed. It is intended for cases where another process or server handles the request or batch processing.

Two Elements of the HTTP Status Line

The status line is the first line the user encounters in the response. Basically, it includes three items, but the most important & usual ones are: –

  1. The HTTP version number shows the HTTP specification & tells the server has tried to make the message comply but didn’t succeed.
  2. A status code is a three-digit number indicating the request user’s result.

HTTP Specification

The HTTP is the typing and negotiation of data representation that allows the system to be built independently based on data being transferred. The World-Wide Web global information initiative has been used since the year 1990. This protocol is referred to as “HTTP/1.1” to define this specification.

Status Code that tells the client has the most updated resource

There is a specific status code that tells the client has the most updated resources & that is 201. This code means that the request has been completed, and a new resource was updated in the system. To identify this, the user can use the URI included in the world wide web & can get the response related to that. Moreover, users can get the most specific URI for the resource in the Location header field.

When to use HTTP Status 202?

Well, I think we all understood what this status code means, but to make it clear, let’s clear it first as well. Status 202 means “that the request has been accepted for processing, but the processing has not been completed yet.” And this status code is useful only when the actual operation is asynchronous.

The Purpose behind the 202 Status Code Response in HTTP

In HTTP, there is no option for the user to re-send a status code from an asynchronous operation, and 202 is one of them. The 202 response is intentionally noncommittal & the user has no option on their side apart from waiting. Its only purpose is to allow a server to accept a request for another process without requiring the user agent’s connection.

Where to find a list of HTTP status codes?

In simple language, status codes are issued by a server in response to a client’s request made on the server. It includes codes from IETF Request for Comments, also known as RFCs, other specifications, and some additional codes used in some common HTTP applications. You can easily find the list on Google as well.

When to use status 202 for asynchronous operations?

The 202 status code is only used when the service knows something will take time. One other scenario is that if the service is reliant on any other asynchronous operation, it has no way of determining the outcome. So, it should return in the form of a “202 Accepted” response.
