To listen for dynamic webhooks with Shopify, you can create a webhook subscription using the Shopify API. Here's a general outline of the steps you would need to take:

1. Register a webhook with Shopify: You can do this by sending a POST request to the /admin/api/2021-07/webhooks.json endpoint with the necessary information, such as the event you want to listen for and the URL where you want the webhook notifications to be sent.
2. Handle the webhook notifications: Once you have registered the webhook, Shopify will send POST requests to the URL you provided whenever the specified event occurs. You will need to create a server or endpoint that can receive these webhook notifications and process them accordingly.
3. Verify the webhook requests: Shopify includes an HMAC header in the webhook requests to verify their authenticity. You will need to calculate the HMAC hash using your shared secret and compare it to the value provided in the request to ensure that it is indeed coming from Shopify.
4. Process the webhook data: Once you have verified the webhook request, you can extract the relevant data from the payload and use it to update your application or perform any other necessary actions.

By following these steps, you can effectively listen for dynamic webhooks with Shopify and keep your application in sync with changes happening on the platform.
