# Register Stored Cards for Account Updater

`POST /payment-methods/account-updater`

Register up to 100 stored cards for Card Account Updater in a single request, identified by their payment method id (`vaulted_token`). Validation is synchronous and all-or-nothing: if any id is invalid the whole request is rejected. Registration itself runs asynchronously, so a `200` response confirms the cards were accepted, not that the update completed. Your account must be enabled for Card Account Updater to use this endpoint.

## Request body

- object
  - `payment_method_ids` string[], required — List of stored payment method ids (`vaulted_token`) to register for Card Account Updater. Between 1 and 100 items; each must be a valid UUID.

## Response `200`

200

- object
  - `accepted` integer — Number of cards accepted for Card Account Updater registration.

## Other responses

- `400` — 400
- `401` — 401
- `403` — 403
