Pauses a subscription's payments. The order's status becomes paused, and so do its upcoming scheduled payments. Nothing is collected until it resumes.

• To pause until a date, send pause_until_date. The order resumes on that date.
• To pause with no end date, send an empty body. The order stays paused until you resume it.

Only subscriptions can be paused. The order needs a card on file, and its status can't be complete, cancelled, paused, suspended or rejected. available_actions.pause tells you in advance.
