Customers

Delete Customer

Delete a customer.

This action cannot be undone and will immediately:

Cancel any active subscriptions for the customer
Revoke all their benefits
Clear any external_id

Use it only in the context of deleting a user within your own service. Otherwise, use more granular API endpoints to cancel a specific subscription or revoke certain benefits.

Note: The customers information will nonetheless be retained for historic orders and subscriptions.

Set anonymize=true to also anonymize PII for GDPR compliance.
