Citi Authorize API is one of 11 APIs that [Citigroup](https://apis.io/providers/citigroup/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Authorization, Consent, Authentication, SCA, and Identity. The published artifact set on APIs.io includes API documentation.

The Citi Authorize API handles the OAuth 2.0 authorization-code and customer-consent flows required for third-party applications to gain scoped access to a customer's Citi account data and to initiate payments. It is the security and consent layer underpinning the rest of the Citi Developer Hub retail catalog, issuing the access and refresh tokens consumed by the Accounts, Money Movement, and Customers APIs. Documentation is HTML-only on the Citi developer surface; no public OpenAPI is published.
