Steps

  1. Clone the Visa TAP reference implementation from github.com/visa/trusted-agent-protocol; review the Agent Registry, Merchant Backend, and CDN Proxy components to understand the trust architecture.
  2. Submit your agent's public key and metadata to the TAP registry via POST /api/v1/agents/register; all verified registrants receive a Visa Trusted Agent credential, which is a signed JSON object.
  3. In your agent's checkout request, include the Trusted Agent credential in the request header as specified in the TAP spec; the merchant's CDN Proxy or backend validates the credential signature before forwarding to payment processing.
  4. Integrate TAP signals into your Stripe or Adyen payment session; both processors accept TAP credentials as part of their agent-aware checkout flows as of early 2026.
  5. Monitor your agent's Agentic Directory listing in the Visa Developer Center; you can update metadata, rotate keys, or revoke credentials through the same portal.
