Safely Retry API calls in Laravel

Idempotency for Laravel is a production-ready package for implementing idempotency in API requests. Clients can safely retry API calls using this package without worrying about duplicate processing.

Using the Idempotency-Key header with a unique UUID, you can send the same key over and over, and the original response is returned without running an operation multiple times:

POST /api/payments HTTP/1.1
Content-Type: application/json
Idempotency-Key: 123e4567-e89b-12d3-a456-426614174000
 
{
  "amount": 1000,
  "currency": "USD",
  "description": "Order #1234"
}

When using this package, API responses include an Idempotency-Key that API users safely use in the future to re-run the operation.
