Payment Accounts

Register payment account

Registers a bank account or wallet for the organization in the route and returns it with its per-rail readiness.

State where the account lives in one of two ways:

Bank account: set kind to bank, send country and currency (for example MX and MXN), and describe the account in accountDetails (for example a clabe).
Wallet: set kind to wallet and send accountDetails of kind address with its chain. Do not send country or currency for a wallet. A wallet requires no registrationInfo, and we ignore any you send.

Registering does not prove that the customer owns the account.

Registration info. A bank account route requires holder fields such as accountHolderName and taxId. We fill each one from the organization’s verified identity when we hold it. When a required field is still missing, the request fails with 422 registration-info-required, and the problem lists every required field in required and the ones still needed in missing, as JSON Pointers into the request (for example #/registrationInfo/taxId). Send the missing fields in registrationInfo and retry. A supplied taxId must match the verified one (422 holder-tax-id-mismatch).

You can send any registration field, including ones this route does not require; we check each value’s format and ignore the fields the route does not use. A name that is not a registration field returns 400 validation-error.

Readiness. A new account starts pending, and so does each rail direction. We register it with the payment provider, then move each direction to ready or rejected. Subscribe to paymentAccountUpdated, or read the account again, and quote a direction once it is ready.

Registering an account again. If the organization already holds the account, you get it back with 200. When a direction was rejected, we register the account with the provider again using the registrationInfo you send, and those directions go back to pending. Otherwise we change nothing. If another organization holds it, the request fails with 409 payment-account-unavailable.

registrationInfo

object

Account holder information a bank account route requires. The route and the organization's account type (personal or business) decide which fields are required: accountHolderName and taxId for bank accounts, plus the personal or business fields on routes that need them. We fill a field from the organization's verified identity when we hold it, so you only need to send the fields a registration-info-required problem lists in missing. You may send other registration fields too: we check their format and ignore the ones the route does not use. A name that is not listed here returns 400 validation-error. Wallets require no fields.
