Highnote

Highnote is a modern, unified embedded-finance platform for card issuing, acquiring, credit, and real-time money movement, with a built-in ledger and program management. The entire platform is driven by a single GraphQL API at https://api.us.highnote.com/graphql, authenticated with a base64-encoded API key over HTTP Basic auth, covering card products, account holders (persons and businesses), financial accounts, payment cards, transactions/authorizations, transfers, collaborative authorization, spend/velocity rules, and webhook notifications.
