Payment Methods require a business account. If you’re interested in using this product, get in touch and our team will follow up to discuss fit.
Payment methods are external bank accounts where you can send fiat from a custodial account. Set them up by logging into the Coinbase Prime UI. Since they’re tied to your entity, any account in your organization can use them. This is the primary mechanism for sending outbound fiat payments from your custodial accounts.

How payment methods fit your integration

  1. List the payment methods linked to your entity to see which bank accounts are available.
  2. Create a transfer with the payment method’s paymentMethodId as the target.
  3. The funds settle to the external bank over the corresponding rail (Fedwire, Swift, or SEPA).
Payment methods are currently supported only as transfer targets (outbound). They cannot be used as a source for inbound funding.
