Decision

Agent-assisted assessment · independently reviewed · 2026-10-01

Use SPT for a controlled pilot if the required Stripe accounts, countries and payment methods are enabled.

Why: Independent sandbox integrations demonstrate useful bounded payment behavior; broader live reliability and security evidence remains limited.
Next: Pin the chosen preview version, implement its authentication flow, and test seller isolation, expiry, retries, concurrency and refunds before scaling.

Constraints

Preview versions require pinning, compatibility checks and regression tests.
Account, country and payment-method eligibility must match the intended flow.
Authentication steps require coordinated agent and seller handling.
Observed April-preview charges consume tokens even below their spending cap.
Seller isolation, expiry rejection and concurrent redemption need testing on the chosen version.
Interrupted streams need an explicit refund or credit policy.
Independent live settlement, fraud and reliability evidence remains limited.
Merchant fees and checkout-channel availability can constrain adoption.
