Concepts
Rails
Rails describe payment capabilities available to a customer.
Rails describe how funds can move for a customer. The supported rail catalog and the rails a customer can request are related, but they are not the same list.
GET /v1/meta/rails returns the broader rail catalog. Customer rail verification currently accepts qualified bank-transfer rails for ach, fedwire, sepa, swift, and pix, plus base aliases for those rails.
Qualified Fiat Rails
Qualified rails use {base}_{variant}. Pooled rails use shared deposit details and support pay-ins. Named rails support dedicated virtual accounts.
| Variant | Meaning |
|---|---|
pooled | Shared deposit details, reference-based reconciliation, pay-ins. |
named | Dedicated virtual account details for a customer. |
