Trying to plug your account into an Authorize.net account? Or figure out how to connect to Shopify? We have solutions that use several different gateways but Authorize.net seems to be the most popular one. We are NOT IT specialists...in fact...this lady has teenagers and 22 years olds regularly make fun of her lack of anything technical...but I do read directions. Here are some I found when looking how to get Authorize.net to work with WooCommerce/Word Press and Shopify.
If you are trying to connect Authorize.net to your WooCommerce on WordPress...we suggest you go to: https://docs.woocommerce.com/document/authorize-net-cim/?_ga=2.154279672.1791325871.1576513368-946041279.1575563272
Hope this helps!
