# Changelog

> Additive changes to the Soap API. Existing integrations keep working; new fields are optional.

<Update label="September 2026" description="Checkouts">
  **`payment_options` on `POST /api/v1/checkouts`.** Pass a list of your enabled payment methods to offer only those on a checkout. The create response and the checkout object now always include a `payment_options` key; it is `null` for requests that do not send the field, so existing integrations are unaffected. See [Limiting Payment Methods](/api-reference/api-v1/checkouts/create#limiting-payment-methods).
