If you want to resolved this issue, please try Magento marketplace below extension which made by Authorize.Net:


If you getting any issue then check the compatible version and upgrade accordingly which can be help your problem.

  • This is not working. Downloaded folder comes with only composer.json file. After running command composer require authorizenet/magento-module-authorizenet Error: [InvalidArgumentException] Could not find a matching version of package authorizenet/magento-module-authorizenet. Check the package spelling, your version constraint and that the package is available in a stability which matches your minimum-stability (alpha).

  • If you are facing issue with this then please try to install extension on any fresh setup and then copy all configured setting from upgrade setup files to your required setup. Composer folder files stores configuration about composer modules settings. Feel free to ask anything if you face any issue. Hope this can be helpful. Thanks Feb 20, 2020 at 6:36
