Authorize.net CIM for Magento 2
Accept and store customer information, including payment methods, with Authorize.net's Customer Information Manager(CIM).
In your Magento 2 root directory run
composer require tnw/module-authorizenetcim
The configuration can be found in the Magento 2 admin panel under
Store->Configuration->Sales->Payment Methods->Authorize.net CIM
Test Mode requires your checkout and admin pages use the HTTPS protocol even in your staging development environments. The correct version of Accetp.js, https://jstest.authorize.net/v1/Accept.js, is loaded when the module is in test mode, but it will error if you attempt to use it over HTTP. You do NOT need a valid SSL certificate for testing.
