when an autocharge is successful, I want to pull the next billing date from the recurring order and place it in custom field on contact record.
I want this to overwrite each time the autocharge is successful, so there will always be the right next billing date in the field.
I want to then be able to use that as a merge field in emails and other actions.
any ideas? the only thing I have found in research is from this link but is there really only this solution from a third party? https://theapiguys.com/how-to-send-billing-reminders-for-upcoming-subscription-payments/
