On September 8, 2022, Shopify removed the Authorize.net integration from their list of approved 3rd party gateways.
While there has been no formal announcement from Shopify or Auth.net, customer service representatives have confirmed that Auth.net is no longer supported for new customers. Service will not be disrupted for active accounts.
The removal of Authorize.net at this point in time is indefinite, but it seems likely that a resolution will be disclosed to the public in the near future.
