Make any HTTP request idempotent by letting the client send an idemotency key in the request headers

idempotency-key

An idempotency key is a unique value that’s generated by a client and sent to an API along with a request. The server stores the key to use for bookkeeping the status of that request on its end. If a request should fail partway through, the client retries with the same idempotency key value, and the server uses it to look up the request’s state and continue from where it left off. The name “idempotency key” comes from Stripe’s API.
