Frequently Asked Questions
Product Information: Shared Payment Token
What is a Shared Payment Token?
A Shared Payment Token is a Stripe mechanism, used within the Agentic Commerce Protocol (ACP), that allows an AI agent to collect a buyer's payment method, tokenize it securely, and pass it to a merchant for processing. The agent never holds raw card credentials; instead, the payment method is tokenized, and the merchant processes the transaction through its own payment provider. Note: The Shared Payment Token is specific to agent-initiated commerce scenarios and may not be relevant for merchants not participating in ACP or agentic commerce workflows.
How does a Shared Payment Token work?
The Shared Payment Token works by tokenizing a buyer's payment method using Stripe. This token is then securely passed by an AI agent to the merchant, allowing the merchant to process the payment through its own payment provider without exposing raw card data. The merchant retains control over payment processing, fulfillment, and the customer relationship. Note: Merchants must be able to accept tokenized payment methods; integration requirements may vary by payment provider.
Does a merchant need to use Stripe to accept Shared Payment Tokens?
No, merchants do not need to use Stripe as their payment processor to accept Shared Payment Tokens. The mechanism enables merchants using other payment providers to participate in ACP agentic commerce by allowing secure transfer of tokenized payment methods. Note: Merchants must ensure their payment provider supports tokenized payments; compatibility may vary.
What security benefits does the Shared Payment Token provide?
The Shared Payment Token ensures that raw card credentials are never exposed to the AI agent or intermediary systems. Only the tokenized payment method is passed to the merchant, reducing the risk of sensitive data exposure. The merchant processes the payment through its own provider, maintaining control over security and compliance. Note: Security depends on proper implementation and the security standards of the merchant's payment provider.
What is the relationship between Shared Payment Token and the Agentic Commerce Protocol (ACP)?
The Shared Payment Token is a core mechanism within the Agentic Commerce Protocol (ACP), enabling secure, agent-initiated payments by allowing AI agents to pass tokenized payment methods to merchants. This trust mechanism makes agent-initiated payments acceptable to merchants and payment networks, even if the merchant does not use Stripe as their payment processor. Note: ACP participation may require additional integration steps beyond token acceptance.
Can Shared Payment Tokens be used with payment providers other than Stripe?
Yes, Shared Payment Tokens are designed to allow merchants using payment providers other than Stripe to participate in agentic commerce. The tokenized payment method can be processed by the merchant's existing provider, provided that provider supports tokenized payments. Note: Not all payment providers may support this mechanism; merchants should verify compatibility before implementation.
Technical Requirements & Implementation
What technical requirements are needed to implement Shared Payment Token support?
To implement Shared Payment Token support, merchants must be able to accept tokenized payment methods from AI agents and process them through their existing payment provider. Integration may require updates to payment processing workflows and verification that the provider supports tokenized transactions. Note: Detailed technical requirements are not publicly documented; merchants should consult their payment provider and 5WPR for specifics.
Use Cases & Benefits
Who can benefit from using Shared Payment Tokens?
Merchants participating in agentic commerce, especially those who want to accept payments initiated by AI agents without exposing raw card data, can benefit from Shared Payment Tokens. This includes businesses using the Agentic Commerce Protocol (ACP) who wish to maintain control over payment processing and customer relationships. Note: Merchants not engaging in agent-initiated commerce may not find this mechanism relevant.
What are the limitations of Shared Payment Tokens?
Shared Payment Tokens require that the merchant's payment provider supports tokenized payments and that the merchant is integrated with the Agentic Commerce Protocol. Not all payment providers may be compatible, and detailed technical limitations are not publicly documented. Merchants should consult their provider and 5WPR for specifics before implementation.

Glossary / Agentic Commerce
Shared Payment Token
A Shared Payment Token is a Stripe mechanism, used within the Agentic Commerce Protocol, that lets an AI agent collect a buyer's payment method, secure it as a token, and pass it to the merchant for processing.
The agent never holds raw card credentials. The buyer's payment method is tokenized, and the merchant processes the transaction through its existing payment provider — keeping control of the payment, the fulfillment, and the customer relationship.
The Shared Payment Token is what allows merchants who do not process payments through Stripe to still participate in ACP-based agentic commerce. It is the trust mechanism that makes agent-initiated payment acceptable to merchants and payment networks.
