  description: >-
    REST API for Pomelo (pomelo.la), the Latin American card-issuing and
    embedded-finance platform. Covers user onboarding and identity verification
    (KYC/KYB), card issuing and lifecycle management, card accounts and balances,
    transaction processing and history, transfers and settlements, and the
    real-time authorizer plus event webhooks. Authentication uses the OAuth 2.0
    client-credentials grant; the issued JWT is sent as a Bearer token on every
    request.
