Subscribing to mandatory GDPR webhooks
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 public app you build for the Shopify platform is GDPR-compliant, regardless of whether your app currently collects personal data. Shopify provides mandatory webhooks to help.
