Create a recovery payment link for a past due subscription

Generates a hosted, signed recovery link that lets the customer pay the outstanding renewal charge for a past_due subscription. Unlike reactivate, which charges server-to-server, this returns a link the merchant can deliver through their own email, SMS, or dashboard. The link carries a self-contained signed token and stays valid until the charge is paid or the subscription is no longer past due.

Change plan POST

Upgrade or change billing interval immediately, optionally applying an Offer. Scheduled changes do not accept offers.

Create subscription POST

Create a subscription for a customer. Commet selects the default price when priceId is omitted and resolves its market from the customer's billing country. Without an offer override, Commet applies the price's automatic introductory Offer. Pass offerId to apply an active compatible Offer directly, or cardPromotionId to preselect a card-eligible Promotional Offer for the initial checkout when card promotions are enabled for the organization. For the initial checkout, provider accepts either a processor name or an exact payment connection ID.
