External Accounts

Understading External Accounts

An External Account represent a bank account not managed by UnblockPay where a customer can receive fiat funds. It is the destination for payout transactions — the bank account where UnblockPay sends fiat money after converting stablecoins.

External Accounts are tied to a customer and must be registered before initiating a payout (except for Pix in Brazil, where you can pass the pix_key and document directly in the payout request).

External Accounts can be first-party or third-party. Use the is_third_party field to indicate when the bank account belongs to someone other than the customer. For example, a customer named "Nick" can register a bank account belonging to "Satoshi" by setting is_third_party: true.

Supported payment rails

UnblockPay supports the following rails for External Accounts:

Rail	Country / Region	Notes
`pix`	🇧🇷 Brazil	Via Pix key (CPF, CNPJ, email, phone, or random key)
`pix_account`	🇧🇷 Brazil	Via full bank account details, when a Pix key is unavailable
`spei`	🇲🇽 Mexico	Via CLABE, debit card, or phone number
`wire`	🇺🇸 United States	Via routing number and bank account number
`sepa`	🇪🇺 Europe (SEPA zone)	Via IBAN and BIC
`cvu`	🇦🇷 Argentina	Via CVU or CBU

How to create an External Account

POST v1/external-accounts

This endpoint registers a new External Account linked to a customer. Each request must include the account_name, the payment_rail, and the corresponding rail-specific object.

You can also include is_third_party: true when the bank account belongs to someone other than the customer.

🇧🇷 External Account in Brazil

UnblockPay supports two Pix methods for Brazilian accounts: a Pix key (simpler, recommended for most cases) and a full bank account via pix_account (for cases where a Pix key is not available).
