Authorize.net eCheck via Shopify?

Topic summary

  • Uses Authorize.net in Shopify to process Visa, MasterCard, and Amex; setup is complete. Also approved for eCheck (ACH bank transfer) on Authorize.net’s virtual terminal.

  • Goal: enable customers to pay via ACH/eCheck directly in the Shopify store checkout by linking Authorize.net’s eCheck capability to Shopify.

  • Constraint: does not want to use any third-party app or plugin, preferring a native/built-in integration since eCheck through Authorize.net is already paid for.

  • Status: no solution or steps provided yet; seeking guidance on how (or if) this integration can be done natively within Shopify.

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!

hi @TheWaterbug , unfortunately if Authorize.net do not have a own official Shopify application, only way around is by connect authorize.net through Shopify app.
