What is a 202 Status Code?

When you navigate through the vast landscape of the web, you've probably encountered HTTP status codes. Among them is the 202 Accepted status code, which signifies that the request has been accepted for processing but has not yet been completed. It's like sending your order at a restaurant; the waiter acknowledges it, but your dish isn't ready yet. Let's delve deeper into what this status code means in the digital realm.

What are the Possible Use Cases for 202 Status Code?

Asynchronous Processing:

Imagine you're uploading a large file to a server. Rather than making the user wait until the upload completes, the server could respond with a 202 status code, indicating that the file is being processed in the background. This allows the user to continue with other tasks while the server handles the heavy lifting.

Batch Operations:

In scenarios where multiple requests are being processed simultaneously, such as batch updates or data synchronizations, the server might respond with 202 to acknowledge receipt of the requests without delaying the entire process.

Rate Limiting:

When an API imposes rate limits on requests, it can respond with a 202 status code if the limit has been reached. This informs the client that the request has been accepted but will not be processed immediately, helping to manage server load and prioritize requests.

How to Implement 202 Status Code in JS

Implementing the 202 status code in JavaScript involves setting the appropriate status code in the HTTP response. Here's a simple example using Node.js and Express:

const express = require('express');
const app = express();'/process', (req, res) => {
  // Processing logic
  res.status(202).send('Request accepted for processing.');

app.listen(3000, () => {
  console.log('Server is running on port 3000');

In this example, when a POST request is made to '/process', the server responds with a 202 status code along with a message indicating that the request has been accepted for processing.

Best Practices for Using 202 Status Code

Provide Meaningful Response:

Include additional information in the response body to inform the client about the status of the request and any further actions they may need to take.

Use in Conjunction with Retry-After Header:

When appropriate, include the Retry-After header in the response to indicate when the client should retry the request if it has not been processed yet.

Handle Timeouts and Errors Gracefully:

Ensure that your application handles cases where processing takes longer than expected or encounters errors, providing appropriate feedback to the client.

How to Test 202 Status Code on Postman

Testing the 202 status code on Postman is straightforward:

  1. Set up a request to your server endpoint.
  2. Send the request and observe the response code.
  3. If the response is 202, it indicates that the server has accepted the request for processing.

How to Test 202 Status Code in DevTools Browser in Chrome

Testing the 202 status code in Chrome DevTools is quick and easy:

  1. Open Chrome DevTools by pressing F12 or right-clicking on the page and selecting "Inspect."
  2. Navigate to the Network tab.
  3. Initiate the request to your server endpoint.
  4. Check the status code of the request in the Network tab. If it's 202, your server is correctly returning the status code.

Frequently Asked Questions

Q: When should I use the 202 status code?

A: Use 202 when you want to acknowledge receipt of a request for processing without implying that it has been completed immediately.

Q: Can I include a response body with the 202 status code?

A: Yes, you can include additional information in the response body to provide context about the processing status or any further actions required.

Q: How long should I wait before retrying a request that returns 202?

A: It depends on your application's logic and the Retry-After header, if provided. Wait for the specified duration before retrying the request.

Q: Does the client need to do anything differently when receiving a 202 response?

A: The client should handle the 202 response by acknowledging that the request has been accepted for processing and may need to check back later for updates.

Q: Are there any performance implications of using the 202 status code?

A: While using 202 itself does not introduce significant performance overhead, ensure that your application efficiently processes requests to avoid bottlenecks.


Understanding the nuances of HTTP status codes, including the 202 Accepted status code, is crucial for effective web development. By employing asynchronous processing, managing batch operations, and implementing best practices, you can optimize the user experience and server performance. Remember to test your implementations thoroughly using tools like Postman and Chrome DevTools.
