About Developer Resources

Highnote provides a comprehensive set of developer tools to build, integrate, and manage your payment solutions. Whether you're issuing cards, processing transactions, or managing accounts, these resources help you get up and running quickly.

Highnote API​

The Highnote GraphQL API is your primary interface for interacting with the Highnote platform. Use it to create card products, manage account holders, issue payment cards, and process transactions. The API supports features like idempotency, search with HQL, custom metadata, and rate limiting to help you build resilient integrations.

Highnote SDKs​

Highnote's SDKs simplify integration by providing client libraries for common platforms. SDKs handle client token management and provide secure access to sensitive operations like revealing payment card details.

Event Notifications​

Event Notifications keep your systems in sync with changes on the Highnote platform. Subscribe to events and configure webhooks for real-time updates on transaction activity, account holder status changes, and other platform events. See the Events Reference for a complete list of available events.

Data Share​

Highnote Data Share provides secure access to your Highnote data through Snowflake. Query and analyze your issuing and acquiring data for reporting and analytics, with most data available within 3 hours. See the Issuing Data Dictionary and Acquiring Data Dictionary for details on available data.
