# Subscription-NextPaymentAt The date when the next payment will be made. Measured in seconds since the Unix epoch. Send it on an update to move the next charge without changing the price. The date must be in the future and no more than five years ahead, and the subscription must be active or past due with a live schedule. A trialing subscription moves with `trialPeriodEnd` instead, and a paused one has to be resumed first. A pending `skipIntervalCount`, `pauseIntervalCount`, `pauseAtPeriodEnd` or `cancelAtPeriodEnd` blocks the change, because it would turn the charge at the new date into a skipped, paused or cancelled cycle instead of a payment. Clear it in the same request by sending `0`, `null` or `false` for that field. Moving the date on its own settles no money. Combine it with `prorate` to charge or refund the time that moves. **integer**integer\ The date when the next payment will be made. Measured in seconds since the Unix epoch.
