Repair mobile payment-intent idempotency without unsafe key reuse
Small compatibility changes can surface at the exact moment a buyer retries.
Retry resilience and protection against unintended duplicate work often pull in different directions.
“Our users lose signal all the time; a retry shouldn’t turn into a payment error.”

What pulls against what
- retry resilience vs. request integrity
- rapid mitigation vs. durable compatibility
- client behavior vs. server invariants
What is at stake
A narrow SDK compatibility break is turning routine network retries into failed checkout starts. A verified fix quickly restores a visible merchant outcome
Why Stripe
At Stripe, these boundaries often matter because payment attempts must remain dependable through unreliable client conditions.
