  name: Discover ProtectBuy 3-D Secure API
  description: ProtectBuy is Discover Global Network's EMV 3-D Secure (3DS) cardholder authentication service. Built on the
    EMVCo 3-D Secure protocol, it lets merchants, acquirers, and 3DS servers authenticate Discover, Diners Club, and network-alliance
    cardholders at checkout, challenge high-risk transactions with a one-time password, and shift liability for card-not-present
    fraud across web, mobile, and connected-device commerce. Documentation and OpenAPI reference are published in the partner-gated
    Discover Developer Center; full specs require partner authentication.

  description: Discover's Secure Remote Commerce (SRC) implementation powers Click to Pay, the EMVCo standard for a streamlined,
    tokenized online checkout across participating card networks. The SRC developer program exposes enrollment, recognition,
    and checkout operations so merchants and payment providers can offer a consistent guest and returning-cardholder experience
    without handling raw PANs. A dedicated SRC developer console and interactive OpenAPI reference are available behind partner
    sign-in on the Discover Developer Center.

  description: Stored Token Services is Discover Global Network's payment tokenization service. It replaces sensitive card
    account numbers with network tokens for card-on-file, digital-wallet, and recurring-payment use cases, and manages the
    token lifecycle — provisioning, updates, and suspension — so merchants and token requestors can secure every digital transaction
    and reduce the scope of stored credential data. The API is documented with interactive OpenAPI reference in the partner-gated
    Discover Developer Center.

    It supports disbursement use cases such as gig-economy payouts, refunds, account-to-account transfers, and insurance or
    lending disbursements. The push-payments API is documented in the partner-gated Discover Developer Center; production
    access is arranged through a Discover account executive.
