# Cancel a membership contract

Permanently cancels an active membership contract in Shopify. This operation stops all future billing and marks the membership as CANCELLED.

Important Notes:
- Permanent Action: Cancellation cannot be undone. A new membership must be created to re-subscribe.
- Email Notification: Cancellation email is automatically sent to the customer
- Activity Logging: Cancellation is logged with reason/feedback for analytics
- Immediate Effect: No future billing attempts will be made

Customer Portal Restrictions:
When called from customer portal, additional validations apply:
- Minimum Cycles: Cannot cancel if membership hasn't completed minimum required billing cycles
- Frozen Memberships: Cannot cancel memberships that are frozen until min cycle completion
- Attribute-Based Limits: Respects any custom attribute-based cancellation restrictions

Cancellation Feedback:
- Optional cancellationFeedback parameter to capture why customer is cancelling
- Common values: 'TOO_EXPENSIVE', 'NO_LONGER_NEEDED', 'SWITCHING_TO_COMPETITOR', 'OTHER'
- Helps merchants understand churn reasons

Use Cases:
- Customer requests to cancel their membership
- Merchant manually cancels membership (e.g., payment issues, customer request)
- Automated cancellation after max cycles reached
