Use these API methods to manage the scheduled payments (billing events) of instalment, subscription, and metered orders.

Instalment orders have multiple billing events, and BillPro creates them all when you create the order.
Subscription orders usually have one or two billing events, because BillPro creates one billing event for each billing cycle.
Metered orders can have any number of billing events because after you create a metered order, you can schedule payments in the UI, and BillPro creates a billing event for each scheduled payment. See Charge for metered products.

In the API, you can update scheduled payments as follows:

Reschedule and skip billing events, and update the amount.
For subscriptions:
1. Adjust the billing cycle of the billing events. To do this, set the scheduled_interval of the last scheduled payment to an integer value, and set the scheduled_duration_unit to DAY, WEEK, MONTH, or YEAR. Note that BillPro does not display these changes in the order.
2. When you adjust the amount of a scheduled payment, BillPro will update the order amount for the future billing events.

For details of how to manage billing events in the UI, see Manage billing events.

When you pause an order, BillPro will not collect any payments and the scheduled payments are in the paused state. Using the API, it is possible to update the scheduled payments to a scheduled state, but in any case, BillPro will not collect any payments until the order is resumed into an active or failed state.
