  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.
