American Express Token Service
American Express network tokens with AEVV cryptograms, provisioned under your TRID. First-class Amex coverage alongside Visa and Mastercard.
American Express Token Service (AETS) is Amex’s network tokenization program for digital commerce. It mirrors the role of VTS and MDES: replace the Amex PAN with a network-managed token, bind it to a token requestor, and supply authorization artifacts issuers recognize. Amex is often deprioritized because PSP tooling is thinner, leaving split estates where Visa and Mastercard are tokenized but Amex still runs on PAN.
Veliro treats AETS as a first-class scheme. Provisioning under your TRID returns the same tok_* your application already stores for other networks, and the unified cryptogram endpoint generates AEVV with correct ECI at authorization. For travel, B2B, and premium retail with outsized Amex share, closing this gap matters to both approval rates and portability.
Amex authorization field placement and program rules differ from Visa and Mastercard, so integrations that hard-code Visa field maps frequently fail on Amex in production. Centralizing AETS cryptogram generation in the credential layer avoids per-PSP Amex defects and keeps recurring indicators correct for rebills.
As with the other schemes, Veliro carries AETS certification and mTLS connectivity while you hold the TRID. That combination means Amex credentials forward to any acquirer you route through, with no re-enrollment when you add or change PSPs.
Lifecycle & authorization
- AETS lifecycle and updater events surface as Veliro webhooks alongside Visa and Mastercard.
- AEVV freshness and recurring indicators follow Amex token program rules; Veliro sets them per transaction.
- BIN-based scheme selection routes Amex cards to AETS automatically at provision time.
