STACK COMPARISON

AI payment authorization vs. payment processing

Authorization policy decides whether an agent may attempt a purchase. Payment processing authorizes, captures and settles money on a payment rail.

SHORT ANSWER

Does MandateShield process or guarantee a payment?

No. MandateShield returns a policy decision and, on strict ALLOW, a short execution reservation. A customer-deployed exclusive executor binds and consumes the reservation, obtains at most one fresh MandateShield claim, and attempts the provider operation with provider-native idempotency. MandateShield does not guarantee exactly-once provider delivery. The payment provider remains responsible for credential handling, network authorization, capture, settlement, refunds and disputes.

MandateShield

Use this side when

  • An autonomous system needs permission checks before it reaches payment code.
  • Business policy spans several processors or payment protocols.
  • You need deterministic evidence of why a purchase attempt was allowed or blocked.

Payment processor

Use this side when

  • The business must accept credentials and move money.
  • Authorization, capture, settlement, refunds or disputes are required.
  • Compliance and network connectivity belong with a regulated payment provider.

PRACTICAL ARCHITECTURE

How they work together

Place MandateShield immediately before a customer-deployed exclusive executor. Strict verification reserves authority; the executor binds it, obtains one fresh MandateShield claim and attempts the exact provider operation with the returned idempotency key. Provider delivery is not exactly-once, and a processor result never changes what the user originally authorized.
