Mandatory webhooks

Mandatory webhooks help you manage the user data that an app collects.

The General Data Protection Regulation (GDPR) sets requirements for any party that collects, stores, or processes the personal data of individuals in Europe. However, Shopify mandates GDPR regulations for all user data, regardless of whether an individual is located in Europe.

You need to ensure that any app that you distribute through the Shopify App Store is GDPR-compliant, regardless of whether your app currently collects personal data. Shopify provides mandatory webhooks to help.

If you don't provide URLs for the mandatory webhooks, or your app doesn't respond to these webhooks as required, then your app will be rejected and you'll need to fix the identified problem before submitting your app for another review.
