The request asks for payment idempotency, which is best served by Stripe, whose payment APIs handle the payment flows that idempotency protects 2. Activepieces' VTEX piece lists a payment-idempotency action covering duplicate payment requests in payment connector code, making it the most direct match for that specific operation 1. Stripe is listed first as the established payments platform; the VTEX skill is the closest match to the exact idempotency guidance requested.
