}Checkout event
HG.Cash sends this webhook when a hosted checkout session completes, needs manual review, or is rejected.
Configure webhookUrl on create or use your default webhook URL in Settings.
On checkout.completed, when a ledger transaction is linked, the payload includes a nested transaction object with the same fields as a TRANSACTION / created webhook (excluding topic and eventType).
