About Fidel API
Fidel API offers a suite of financial infrastructure APIs that enable developers to build on top of the payment card rails. The platform provides access to real-time, enriched transaction data from Visa, Mastercard, and American Express. This allows companies to create highly contextual, event-driven user experiences. Key use cases include powering loyalty and rewards programs by tracking purchases, issuing real-time digital receipts, validating card ownership for expense management, and tracking marketing campaign attribution. The API-first approach provides developers with a sandbox environment and tools to quickly integrate card-linking and payment data functionalities into their applications.
