# checkout.ready

> A checkout link is ready to share with the customer.

## When this fires

When a subscription is created without a payment method on file, Commet generates a hosted checkout link for the first invoice and fires this event as soon as the link is ready. Commet also emails the link to the customer — this webhook lets you deliver it through your own channels (in-app banner, chat, SMS) instead of relying on email alone.

The link stays valid until the invoice is paid or voided. Trials with their own checkout flow fire `trial.checkout_ready` instead.

Use the `checkoutUrl` to put the payment link in front of the customer wherever they already are.
