Payments take an idempotency key. Refunds do not, so a timeout on our side means we genuinely cannot tell whether the customer has been refunded once or twice without going to look.

That is an inconsistency in our API rather than a gap in yours, and refunds are the worse half to have left out. Checking whether anything downstream assumes refunds are unkeyed before we commit to a date.
