​
Overview

Deactivate a customer by marking them as inactive. This is a soft delete—the customer record is preserved for historical data integrity but hidden from active customer lists.
Customers with active subscriptions cannot be deleted. Cancel or complete all subscriptions first.

​
What Happens When You Delete a Customer

  1. Customer status changes to inactive
  2. Customer hidden from default list queries
  3. Historical orders and subscriptions preserved
  4. New orders cannot be created for this customer
  5. Reporting data remains intact

​
Common Use Cases

  • Data Cleanup: Remove test customers or duplicate records
  • Account Closure: Customer requested account deletion
  • Compliance: Remove inactive customers per data retention policies
  • Fraud Prevention: Disable accounts flagged for suspicious activity

​
Prerequisites

Before deleting a customer, ensure:
  1. No active subscriptions
  2. No pending orders
  3. All devices returned (if applicable)
async function canDeleteCustomer(customerId) {
  const customer = await getCustomer(customerId);

  // Check for active subscriptions
  if (customer.profitability.activeDevices > 0) {
    console.log('Cannot delete: Customer has active subscriptions');
    return false;
  }

  // Check for pending orders
  const { orders } = await listOrders({
    customerId,
    status: 'pending'
  });

  if (orders.length > 0) {
    console.log('Cannot delete: Customer has pending orders');
    return false;
  }

  return true;
}

​
Reactivating a Customer

To reactivate a deleted customer, use Update Customer: 
PUT /v1/customers/{customerId}

}
