Description

Support for one-time payments and recurring subscriptions.
Automated webhook processing for payments, recurring subscriptions, chargebacks, and subscription terminations.
Automatic deactivation of incompatible trial periods to ensure compliance with terms and conditions.
Clean UI: Removes unnecessary form fields for a higher conversion rate.
Users with active chargebacks are automatically blocked from accessing content.
