Agent Payments Protocol

Start with a sandbox or test merchant and define the commerce action the agent must perform: open agent-payment protocol for securely expressing user intent, authorization, credentials, and payment mandates in agentic transactions. Connect only the catalog, cart, checkout, identity, or payment permissions needed for that path.

Use Agent Payments Protocol to produce or execute the first version, then inspect the underlying details. Verify product titles, variants, prices, stock, tax and shipping behavior for commerce tools; for builders, inspect every generated page, navigation path, mobile layout, form, metadata, and integration.

Keep consequential actions controlled. Payment or order execution should use explicit authorization, spending limits, auditable credentials, and clear confirmation rules. Generated sites should be tested for accessibility, security, privacy, performance, and ownership before launch.

After rollout, monitor failed searches or actions, abandoned checkouts, agent errors, conversion, latency, cost, data freshness, and user corrections. Re-test whenever protocols, models, merchant feeds, payment rails, or connected applications change.
