Enroll users in separate groups based on payment method

Good evening, I would need to place users in two separate moodle groups based on the payment method chosen in e-commerce (Virtuemart). How can I do this?

I am sorry, but It is not possible to do that with Joomdle.
You would need to create a new Joomla plugin to call enrolment with different params according to payment method.
You would also need need new enrolment web services, added in a new Moodle plugin, as I don't think currently available ones could work as you need.
