  title: Pismo Accounts Transactions API
  description: Specification of the Pismo cloud-native issuer-processing and core-banking platform API. Covers accounts, customers, cards, authorizations, transactions and statements, programs, and event/webhook configuration. Pismo is a Visa-owned platform (acquired January 2024). Authentication uses OAuth2 client-credentials to obtain a Bearer access token; account-scoped endpoints additionally require an account-specific token that encodes a Pismo account ID.
