Map the vocabulary of open finance, modern payment messaging, and regulated API access.
Browse all topic termsOpen banking vocabulary sits at the intersection of regulated API access, account permissions, and payment messaging standards. This hub focuses on how terms such as PSD2, SCA, ISO 20022, and variable recurring payments connect user consent with bank-to-bank execution.
Standards such as SWIFT, SEPA, BACS, and ISO 20022 shape how payment data is structured, validated, and routed. They are essential for understanding why some payment products scale cleanly across jurisdictions while others remain market-specific.
For fintech teams, this topic is not just about compliance. It influences onboarding design, recurring payment architecture, treasury operations, and the boundaries between banking-as-a-service, account-to-account payments, and embedded finance.
