Highnote Acquiring API is one of 7 APIs that [Highnote](https://apis.io/providers/highnote/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Card Acquiring, Payment Processing, Authorizations, Clearing, and Merchant Payments. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and an API reference.

Accept and process payments as a merchant acquirer through the single GraphQL endpoint. Authorize, capture, charge, and cancel payment transactions (authorizePaymentCard, capturePaymentTransaction, chargePaymentCard), handle incremental and force captures, and manage the acquiring transaction lifecycle. Highnote's unified platform pairs acquiring with issuing and a real-time ledger so funds flow can be orchestrated on one system of record.
