# Adds customer and payment method details to the Refunds API

## What’s new

Adds three new readable properties to the [Refunds](https://docs.stripe.com/api/refunds/object.md?api-version=2026-07-29.dahlia) object:

- [customer](https://docs.stripe.com/api/refunds/object.md?api-version=2026-07-29.dahlia#refund_object-customer): The ID of the customer associated with the refund. You can expand this property to retrieve the full [Customer](https://docs.stripe.com/api/customers/object.md?api-version=2026-07-29.dahlia) object.
- [customer_account](https://docs.stripe.com/api/refunds/object.md?api-version=2026-07-29.dahlia#refund_object-customer_account): The ID of the account associated with the refund.
- [payment_method](https://docs.stripe.com/api/refunds/object.md?api-version=2026-07-29.dahlia#refund_object-payment_method): The ID of the payment method associated with the refund. You can expand this property to retrieve the full [PaymentMethod](https://docs.stripe.com/api/payment_methods/object.md?api-version=2026-07-29.dahlia) object.

These properties are returned on all `/v1/refunds` endpoints and are available for both linked and unlinked card refunds.

## Impact

You can now retrieve customer and payment method details directly from a [Refund](https://docs.stripe.com/api/refunds/object.md?api-version=2026-07-29.dahlia) object without making additional API calls. To access the full object details, pass `customer`, `customer_account`, or `payment_method` in the [expand](https://docs.stripe.com/expand.md) array of your request.
