Authorize.net is building a new connection to Shopify’s updated platform, and our legacy connection will be decommissioned. The new connection is expected to be available before the end of 2023. Shopify administrator will need to install and activate the new application and deactivate the legacy application.
If the necessary changes are not made by March 31, 2024, the payment card option at checkout will disappear.
Additionally, information and instructions as they become available can also be found in this support article.
