To verify a Shopify webhook, you can follow these steps:
- Retrieve the webhook data from the request.
- Extract the 'X-Shopify-Hmac-SHA256' header value from the request, which contains the webhook signature.
- Compute the HMAC-SHA256 hash of the request body using your Shopify webhook secret.
- Compare the computed hash with the value in the 'X-Shopify-Hmac-SHA256' header.
- If the values match, the webhook is verified as authentic.
By following these steps, you can ensure that the webhook received from Shopify is genuine and secure.

How to verify Shopify webhook signature in a Laravel application?
To verify a Shopify webhook signature in a Laravel application, you can follow these steps:
- Retrieve the incoming webhook data and the signature from the request.
- Install the laravel-shopify-webhook package by running the following command in your terminal:
1
|
composer require oliboy50/laravel-shopify-webhook
|
- Use the WebhookSignature class from the package to verify the signature. Here's an example of how you can verify a webhook signature in your controller:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
use Illuminate\Http\Request; use Oliboy\LaravelShopify\Webhook\WebhookSignature; class WebhookController extends Controller { public function verifyWebhook(Request $request) { $data = $request->getContent(); $hmacHeader = $request->header('X-Shopify-Hmac-SHA256'); // Replace 'YOUR_SHARED_SECRET' with your Shopify app's webhook secret key $sharedSecret = 'YOUR_SHARED_SECRET'; $webhookSignature = new WebhookSignature($data, $sharedSecret); if ($webhookSignature->isValid($hmacHeader)) { // Signature is valid return response()->json(['message' => 'Webhook signature is valid'], 200); } else { // Signature is invalid return response()->json(['message' => 'Webhook signature is invalid'], 401); } } } |
- Make sure to replace 'YOUR_SHARED_SECRET' with your Shopify app's webhook secret key.
By following these steps, you can verify the signature of a Shopify webhook in your Laravel application.
How to verify Shopify webhook using Python?
To verify a Shopify webhook in Python, you can use the Flask web framework to create a simple web server that listens for incoming webhook requests. When a webhook request is received, you can verify the request by comparing its HMAC signature to the expected signature generated using your webhook secret.
Here is an example of how you can verify a Shopify webhook in Python using Flask:
- Install Flask library:
1
|
pip install Flask
|
- Create a Python script with the following code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 |
from flask import Flask, request, abort import hmac import hashlib app = Flask(__name) SHOPIFY_WEBHOOK_SECRET = 'your_webhook_secret_here' @app.route('/webhook', methods=['POST']) def handle_webhook(): request_data = request.get_data() hmac_header = request.headers.get('X-Shopify-Hmac-Sha256') if not verify_webhook(hmac_header, request_data): abort(401) # Perform your webhook handling logic here return 'Webhook received and verified successfully', 200 def verify_webhook(hmac_header, request_data): if hmac_header is None: return False digest = hmac.new(SHOPIFY_WEBHOOK_SECRET.encode('utf-8'), request_data, hashlib.sha256).hexdigest() return hmac.compare_digest(digest, hmac_header) if __name__ == '__main__': app.run(port=5000) |
- Replace 'your_webhook_secret_here' with your actual Shopify webhook secret.
- Run the Python script and start the Flask server.
- Set up your webhook in your Shopify store to send webhook events to the URL of your Flask server (e.g. http://localhost:5000/webhook).
- The Flask server will receive the webhook request and verify it using the HMAC signature. If the signature is valid, the webhook request will be processed, otherwise, a 401 Unauthorized response will be returned.
This is a basic example of how you can verify a Shopify webhook in Python using Flask. You may need to adapt the code to suit your specific requirements and error handling.
How to verify Shopify webhook in PHP?
To verify a Shopify webhook in PHP, you can follow these steps:
- Get the request headers and body from the incoming webhook request:
1 2 |
$headers = getallheaders(); $body = file_get_contents('php://input'); |
- Create a signature using the shared secret and the request body:
1 2 |
$shared_secret = 'your_shared_secret'; $computed_signature = base64_encode(hash_hmac('sha256', $body, $shared_secret, true)); |
- Compare the computed signature with the signature in the request headers:
1 2 3 4 5 6 7 |
if($headers['X-Shopify-Hmac-SHA256'] === $computed_signature) { // Webhook is verified echo 'Webhook verified!'; } else { // Webhook is not verified echo 'Webhook verification failed!'; } |
By following these steps, you can verify a Shopify webhook in PHP by comparing the computed HMAC signature with the signature provided in the request headers.
How to verify Shopify webhook without using third-party libraries?
You can verify a Shopify webhook without using third-party libraries by following these steps:
- Extract the HMAC signature from the headers of the webhook request. This signature is located in the 'X-Shopify-Hmac-Sha256' header.
- Calculate the HMAC signature of the request body using your Shopify webhook secret key (available in your Shopify admin settings).
- Compare the calculated HMAC signature with the signature extracted from the request headers.
- If the two signatures match, the webhook request is verified and you can proceed with processing the webhook payload. If the signatures do not match, discard the webhook request as it may not be from Shopify.
Below is a sample code snippet in Python illustrating how to verify a Shopify webhook without using third-party libraries:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
import hmac import hashlib import base64 def verify_webhook(data, hmac_header, secret): data = str(data).encode('utf-8') secret = str(secret).encode('utf-8') computed_hmac = base64.b64encode(hmac.new(secret, data, hashlib.sha256).digest()) computed_hmac = computed_hmac.decode('utf-8') return hmac.compare_digest(computed_hmac, hmac_header) # Usage webhook_data = "example webhook payload" webhook_hmac_header = "example hmac signature from headers" webhook_secret = "your shopify webhook secret key" if verify_webhook(webhook_data, webhook_hmac_header, webhook_secret): print("Webhook request verified") else: print("Webhook request not verified") |
Replace the 'webhook_data', 'webhook_hmac_header', and 'webhook_secret' variables with the actual data and HMAC signature extracted from the webhook request headers. This code snippet will verify the webhook request payload without using any third-party libraries.
What is the process for verifying Shopify webhook signatures?
Verifying Shopify webhook signatures involves a few steps:
- Retrieve the webhook data and signature from the request headers. The webhook data typically includes the request body and a timestamp.
- Retrieve your Shopify webhook secret key. This key is used to create the HMAC signature for the webhook data.
- Using the HMAC algorithm and the webhook secret key, generate a new HMAC signature based on the webhook data from the request.
- Compare the generated signature with the signature sent in the request headers. If they match, the webhook data is considered authentic and has not been tampered with during transmission. If they do not match, the webhook should be rejected and not processed.
By following this process, you can ensure that the webhook data received from Shopify is legitimate and secure.
