Implementing Idempotency for Reliable Payment APIs

Prevent duplicate charges from retries and network glitches by using Stripe idempotency keys correctly across your payment API calls.

The Duplicate Charge Problem

Networks fail mid-request. If your code retries a payment without protection, the customer can be charged twice. Idempotency solves this.

What Is Idempotency?

An idempotent operation can be repeated with the same result. Calling it once or five times produces a single effect.

  • Safe retries
  • No accidental duplicates
