Again, this article is for any ProductCart merchant who is using Authorize.net or plans to use it with ProductCart versions 5.2.1 to v5.4.1. This upgrade is included if you are running [**ProductCart version 5.5.0**](https://productcart-kb.nsource.com/kb/productcart-version-5-5?hsLang=en). If you want to guarantee uninterrupted service and have a more secure checkout, then the new API will be a requirement.

Read article here [https://support.authorize.net/knowledgebase/Knowledgearticle/?code=KA-07157](https://support.authorize.net/knowledgebase/Knowledgearticle/?code=KA-07157) - Customer checkout and payment experience remain the same, with card form on it’s own page after the one-page-checkout. ### **What to Know Before Installing - FAQs** #### **What versions of ProductCart will the New Authorize.net integration be compatible?** This one install set will work for ProductCart versions v5.2.1 to v5.4.1. This install set is included in ProductCart version 5.5.0. #### **Does your account type or connection need updated?** Account type and credentials should remain the same. As far as connections, merchant clients may need to go into their Authorize Account and create a set of NEW keys for API access and plug the into the ProductCart Authorize.net configuration screen. However, these things should be handled through the onboarding process automatically after installation. #### **How to set up Authorize.net after installation?** Please refer to our **[INSTALL ARTICLE](https://docs.productcart.com/link/article/new-authorize-api-install-settings)** for full details. #### **Does the New Authorize use 3DS?** No it doesn't use 3DS secure. #### Is the New Authorize API more secure? Yes, the new Authorize API has improved PCI compliance since it uses OAuth 2.0 which is a current industry standard and credit cards are no longer be stored on the ProductCart database as in the previous AIM integration.  The API also provides better security than its predecessors (like AIM) due to the fact it runs on frequently changing access tokens which validate the merchant with Authorize. Previous integrations use fixed keys which are at higher risk of a "middle man" attack if secret keys are compromised. This is not the case with the new API, as the secure validation is checked and renewed constantly. #### **What existing folders/files are affected?** New files will overlay over the Legacy AIM integration files, with the additional new gateway files which shouldn’t interfere with other payment applications. #### What other payment options exist? For a list of complete payment solutions through ProductCart, read about our [Supported Gateways](https://productcart-kb.nsource.com/kb/supported-payment-gateways1?hsLang=en). #### **Do I need the New Authorize.net API?** Yes, all previous integrations have been depreciated and are considered legacy by Authorize. #### Are there install instructions for New Authorize API? Yes, please refer to our **[INSTALL ARTICLE](https://docs.productcart.com/link/article/new-authorize-api-install-settings) **for full details. #### Does the New Authorize API Look Different? Both the Legacy AIM integration and API look almost identical. The major differences is that the New API has only **four steps** in settings compared to **five steps**, and a "**Connect/Refresh**" button on the top of the settings page for connecting your account or a different account.  **NOTE**: The new API doesn't store credit cards on ProductCart to reauthorize and charge customers anything more than the original order total. However, if your business model requires the flexibility to charge more after a completed "Authorized" order, it is still possible.  You just need to add a processing fee by a fixed amount or percentage on Step 2 of settings to accommodate the need for making increased price adjustments after taxes, shipping or other fees are calculated post completed order. **NEW Authorize API Screenshot (When Connected)** ![NEW_AuthorizeAPI_Settings-2](https://productcart-kb.nsource.com/hs-fs/hubfs/NEW_AuthorizeAPI_Settings-2.png?width=670&height=432&name=NEW_AuthorizeAPI_Settings-2.png) **Legacy Authorize AIM Screenshot** ![OLD_AuthorizeAIM_Settings-1](https://productcart-kb.nsource.com/hs-fs/hubfs/OLD_AuthorizeAIM_Settings-1.png?width=670&height=533&name=OLD_AuthorizeAIM_Settings-1.png) ### **Helpful Authorize Links** This page shows that new Authorize API is the current alternative and replacing SOAP API + AIM -> [https://developer.authorize.net/api/upgrade\_guide.html](https://developer.authorize.net/api/upgrade_guide.html) Features and Details of API -> [https://support.authorize.net/knowledgebase/Knowledgearticle/?code=000001271](https://support.authorize.net/knowledgebase/Knowledgearticle/?code=000001271) For information about the ProductCart Authorize Patch for AIM Integration, [click here](https://docs.productcart.com/link/article/authorize.net-visa-changes-in-integration-2024)! - [Managing Your Products](https://productcart-kb.nsource.com/kb/managing-your-products?hsLang=en) - [Managing Orders](https://productcart-kb.nsource.com/kb/managing-orders?hsLang=en) - [Managing Customers](https://productcart-kb.nsource.com/kb/managing-customers?hsLang=en) - [Getting Started](https://productcart-kb.nsource.com/kb/getting-started?hsLang=en) - [Apparel Add-On](https://productcart-kb.nsource.com/kb/apparel-add-on?hsLang=en) - [Upgrading ProductCart](https://productcart-kb.nsource.com/kb/upgrading-productcart?hsLang=en) - [Change Logs](https://productcart-kb.nsource.com/kb/change-logs?hsLang=en) - [Store Settings](https://productcart-kb.nsource.com/kb/store-settings?hsLang=en) - [Security](https://productcart-kb.nsource.com/kb/security?hsLang=en) - [Shipping Options](https://productcart-kb.nsource.com/kb/shipping-options?hsLang=en) - [Payment Options](https://productcart-kb.nsource.com/kb/payment-options?hsLang=en) - [Tax Options](https://productcart-kb.nsource.com/kb/tax-options?hsLang=en) - [Advanced Technical Articles](https://productcart-kb.nsource.com/kb/advanced-technical-articles?hsLang=en) - [Pages](https://productcart-kb.nsource.com/kb/pages?hsLang=en) - [What's New In ProductCart](https://productcart-kb.nsource.com/kb/whats-new-in-productcart?hsLang=en) - [Marketing](https://productcart-kb.nsource.com/kb/marketing?hsLang=en) - [How To's](https://productcart-kb.nsource.com/kb/how-tos?hsLang=en) - [Google Analytics](https://productcart-kb.nsource.com/kb/google-analytics?hsLang=en) - [QuickBooks Sync](https://productcart-kb.nsource.com/kb/quickbooks-sync?hsLang=en) - [Default](https://productcart-kb.nsource.com/kb/default?hsLang=en) - [Configurator](https://productcart-kb.nsource.com/kb/configurator?hsLang=en) - [SEO](https://productcart-kb.nsource.com/kb/seo?hsLang=en) - [Mobile Commerce](https://productcart-kb.nsource.com/kb/mobile-commerce?hsLang=en) - [Troubleshooting](https://productcart-kb.nsource.com/kb/troubleshooting?hsLang=en) - [Customizing Your ProductCart Store](https://productcart-kb.nsource.com/kb/customizing-your-productcart-store?hsLang=en) - [ProductCart Apps](https://productcart-kb.nsource.com/kb/productcart-apps?hsLang=en) - [Hidden Topic](https://productcart-kb.nsource.com/kb/hidden-topic?hsLang=en) - [Reports and Exports](https://productcart-kb.nsource.com/kb/reports-and-exports?hsLang=en) [![ProductCart Logo](https://productcart-kb.nsource.com/hs-fs/hubfs/pc_logo.png?width=200&height=93&name=pc_logo.png "ProductCart Logo")](https://netsourceinc.com) NetSource Commerce, Inc. **|** Headquarters - 3700 South Pine Avenue, Ocala, FL 34471 **|** Tel [(800) 709-3240](tel:+8007093240) **|** Fax (352) 401-0353 [mailto:help@productcart.com](mailto:help@productcart.com) Copyright © 2026, NetSource
