Stripe Idempotency Key Not Implemented

Same charge processes multiple times if request retries. Customers are charged twice for one payment.

Idempotency keys prevent duplicate processing on network retries.

Common Causes

  1. No Idempotency-Key header sent to Stripe
  2. Using random key instead of deterministic
  3. Not reusing key on retries
  4. Stripe idempotency not enabled in SDK

How to Fix It

Generate idempotency key from order ID (deterministic). Send with every Stripe request: RequestOptions.setIdempotencyKey(). For retry logic, reuse same key. Store processed keys with results to detect duplicates. Stripe repeats response for identical key within 24 hours.
