Authorize.net (AIM & SIM) in Extension Discussion Posted February 24 Any plans for an updated free or paid authorize.net payment module? According to the Auth.net Website SIM and AIM are on death row... Quote We will soon announce an end of life timeline for SIM, so we encourage you to upgrade your SIM solutions to use Accept Hosted. Authorize.Net Accept Hosted is a mobile-optimized, PCI DSS SAQ-A compliant solution for accepting payments. Accept Hosted is a replacement for SIM with many advantages, including the freedom to accept payments while reducing PCI scope and development efforts. Something to think about and could prevent panic and hassle down the road.
