I already use Authorize.net to process Visa, MasterCard, and Amex payments through Shopify, so that’s all set up.
I also have been approved to capture eCheck payments on Authorize.net’s online virtual terminal, so that’s all set up.
How do I link the two to allow my customers to pay via ACH on my Shopify store?
I do NOT want to use a 3rd party app/plugin for this, since I’m already paying Authorize.net for the privilege of using their eCheck service.
Thanks!
