Apple Pay + Shopify + Authorize.net

[chunkindunkin]

I've spent hours scouring the web and working through support to get Apple Pay working through Authorize.net's payment gateway for Shopify with no luck.

My Apple Developer Account has a Merchant ID, Apple Pay Payment Processing Certificate (from the Authorize.net CSR), and a verified Merchant Domain.

I generated the API ID and Transaction Keys in Authorize.net and entered them into my Shopify store as instructed.

Apple Pay successfully completes the transaction, and the order page generated by Shopify shows this error. The failed payment transaction doesn't show up on Authorize.net or on Shopify.

I appreciate any help or guidance!

It may be that if you make a phone call to tech support, and press the "#" symbol twice if you don't have a gateway ID, you can explain to the person what is happening, and they can test with your configuration, and offer a suggestion or guidance about the error.
