Agentic AI Adopts New Payments Protocols

Google Cloud announced the Agent Payments Protocol (AP2) in a Google Cloud blog post dated September 16, 2025, describing AP2 as an open, payment-agnostic protocol to initiate and transact agent-led payments across platforms. The Google post lists three core concerns AP2 addresses: authorization, authenticity, and accountability. The post also says Google is collaborating with more than 60 organizations, naming partners including Adyen, American Express, Ant International, Coinbase, Mastercard, Paypal, Revolut, and others.

Ant Group introduced the Agentic Mobile Protocol (AMP) at its FinTech forum in Kuala Lumpur, according to PYMNTS. PYMNTS reports that Ant describes AMP as an open-sourced protocol built for mobile interfaces, super apps and digital wallets. PYMNTS cites Ant materials claiming AMP cuts the number of steps required to link a payment agent to a digital wallet by 50%, and that the Alipay+ network connects more than 40 wallet partners, covering 1.8 billion user accounts and 150 million merchants.

AP2 and AMP address the same technical gap from different angles: existing payment systems assume a human is the actor, while agentic commerce requires machine-initiated flows with verifiable delegated authority. Per the Google post, AP2 centers on mechanisms to prove a user granted an agent specific purchase authority, to let merchants verify that an agent request reflects user intent, and to enable post-hoc accountability. PYMNTS coverage of AMP emphasizes streamlined wallet integration and mobile-first credentialing to avoid multi-step card binding.

Industry observers note that the rise of agentic interfaces creates friction across identity, authentication and risk management layers. Companies and payments networks have started to propose shared protocols to avoid a fragmented patchwork of proprietary integrations. Google's collaborator list and Ant's linkage with card networks such as Mastercard and Visa, as reported by PYMNTS, reflect an early push by major incumbents to codify standards rather than leave implementation to isolated vendors.

Observers following the sector will watch for: uptake of AP2 or AMP by major wallets and merchants; pilots from card networks and processors that translate protocol primitives into settlements and chargeback rules; how verifiable credentials or mandate models are standardized; and whether regulators publish guidance on machine-authorized transactions. Adoption by aggregator platforms and demonstrable reductions in friction or fraud rates will be the clearest indicators of practical impact.
