Auto top-up is off unless an owner of your account turns it on. When it’s on, you authorize us, through Stripe, to charge your saved card the top-up amount you chose, without asking each time, whenever your balance falls below the threshold you chose.
Automatic charges never add up to more than the monthly limit you set in a calendar month (UTC). If the next top-up would go over the limit, we charge only what’s left under it, or nothing until the next month. Funds you add yourself don’t count toward the limit.
An owner can change the amounts or turn auto top-up off at any time on the console’s Usage & billing page; the change applies to charges after it’s saved. If an automatic charge fails, auto top-up pauses until you add funds or update your card.
