Update Stripe Api Subscriptions -- 2

Hi. I need a freelancer to update existing Stripe API subscriptions. 3 subscriptions must have their prices changed and 1 subscription must be changed from a monthly to a weekly recurring billing cycle. It's an easy job but you must fully understand Stripe API and don't make a mess. Explain in detail your experience with Stripe API Subscriptions. This is a 30 min - 1-hour job, no more. Please, make offers accordingly.
