Stripe suggests adding invoice items in the invoice.created webhook that happens approximately an hour before a subscription is charged. My concern is what happens if the site is down (or there's an error in the webhook). Stripe will charge the invoice without the items I wanted to add to that? This will result in big trouble if it happens for a substantial number of subscriptions. Is there a way to avoid this?

Ok, it seems to be described in the docs.
If your webhooks do not all respond successfully, Stripe will continue retrying the webhooks every hour and will not attempt to pay the invoice. After 3 days, Stripe will attempt to pay the invoice regardless of whether or not your webhooks have succeeded.

3 days should be enough to react to an issue with webhooks, and there's also charge webhook where I can check the amount.
