`customer.points_expire_at`

Sample payloads above use "2027-01-31T23:59:59.000Z" when an expiration date applies (Last Activity or Date Earned policies); the field is null when your policy is Never expire.

The date when the customer's points are set to expire. The value depends on your store's Points expiration policy:

Last Activity — Returns the calculated expiration date based on the customer's last activity.
Date Earned — Returns the next upcoming expiration date across all point batches.
Never expire — Returns null.

For Date Earned policies, customers may have multiple point batches with different expiration dates; this field reflects only the closest upcoming expiration.

The same semantics apply to GET /v1/customers, GET /v2/customers, and GET /api/v2/customers (Fetch Customer Details and Fetch All Recently Updated Customers).
