The Payment Form - Joomla User Groups plugin automatically assigns logged-in users to specified Joomla user groups after they complete a payment. This powerful automation feature enables access control, and premium content delivery based on payment completion. This plugin is essential for creating paid membership levels, granting access to restricted content, or managing user permissions based on payment transactions.

With that setup, when users complete payment using the form (note that they need to register for an account on the form or already logged in), they will be assigned to the configured user groups.
