TOPIC: Payment Gateway support - sofortueberweisung

I need to develop a plugin to support sofortueberweisung payment gateway. is there any guide or examples.

Hello. DT Register has many payment gateways included. They are NOT implemented as separate plugins. They're just built into the component... which is what you would need to do. There is no documentation on how to add your own gateway. The main gateway files are at:

/components/com_dtregister/lib/payment/

So you'd need a file there... then you'd need to modify a couple other files to add your gateway to the list of options and config setup. We can point you in the right direction, but we won't assist with customizing your own gateway outside of doing a custom project with us. Thanks.

I am having an issue where I need to get to that file, but it does not exist in my dt register 2.7
I navigate to /components/com_dtregister/lib/
but there is no "payment" file in this folder. Any idea where it has gone???
