Capital One Shop with Rewards API
The Capital One Shop with Rewards API lets partners integrate Capital One credit card reward points and benefits into online shopping experiences, so cardholders can unlock deals and redeem accumulated rewards at participating retailers. It powers reward-driven commerce and checkout scenarios. Access is OAuth 2.0 secured through DevExchange, exercised in a sandbox and gated behind partner approval for production. The developer documentation is HTML-only on the DevExchange portal, and no publicly downloadable machine-readable specification is provided.
