Action: Edit recurring payment subscription settings

This will allow you to change various parameters related to a particular recurring payment subscription from one particular lead.

A few limitations to keep in mind:

  • PayPal subscriptions cannot be edited, since Paypal manages the subscriptions in-house and they do not allow modifications from external sources.
  • Payment subscriptions with status Cancelled or Terminated (meaning payment plans where all scheduled payments have already been paid) cannot be changed since they are not technically active anymore.

POST subscription_id* integer
POST subscription_product_id** *** integer
POST subscription_price_point** *** integer
