Record usage for a metered subscription. Theidempotency_key is required so
a retried report cannot bill a customer twice. Derive it from the thing being
reported, such as the subscription and the window, rather than generating a
random one.Authorizations
Your Reclack API key. The prefix decides the environment: rk_sandbox_ for test chains, rk_live_ for production.
Path Parameters
The subscription being metered.
