Idempotency

Idempotency ensures that retrying a request produces the same result as the original request, preventing duplicate resource creation. This is essential for payment operations where network failures or timeouts may require request retries.

Scenario	Behavior
First request	Processed normally; response cached against the key
Retry with the same payload	Returns a 409 Conflict error

Idempotency is supported on all POST endpoints that create resources:

Endpoint	Resource
