Accounts

Add a rail to an external bank account

Enable ACH or Wire on an active US USD external bank account. Existing rails remain available if the addition fails. Use the routing number the bank publishes for the requested rail. Where the account supports a separate routing number per rail, a number differing from the account's is registered for the rail being added and the rails already on the account keep theirs; where the account's rails share one routing number, a differing number is rejected. A rail that already holds a different routing number is not repointed.

Request body

rail'ach' | 'wire' required

routing_numberstring required

Bank-confirmed routing number for the requested rail. On an account that supports a separate routing number per rail, a number that differs from the account's registers that ABA for the rail being added and leaves the rails already on the account on theirs; on an account whose rails share one routing number, only the account's own is accepted. A rail that already holds a different routing number is not repointed.

Response

Rail enabled or already available; the account id is unchanged.
