ProductCart recommends and fully integrates with Authorize.net and Stripe Payments. However, Stripe may not be available for merchants using ProductCart 5.3 and older.  2. PayPal Express is also be a viable payment option, but it won't take credit cards and customer will need a PayPal account. ### What is Known About this Error from PayPal At the time of writing this article, nothing has been posted directly from PayPal about this error. However, PayPal has made clear two things which lead us to believe Payments Pro will no longer accept website credit card payments as is. #### 1.  Existing Users of Payments Pro Need to Upgrade PayPal says in [this article](https://developer.paypal.com/api/nvp-soap/payflow/website-payments-pro)dated on **September 19, 2024**, that Payments Pro users will need to upgrade to PayPal's Advanced Debit and Credit solution. We'd recommend speaking to a PayPal representative to understand what that looks like for your business. See screenshot below or read full article [here](https://developer.paypal.com/api/nvp-soap/payflow/website-payments-pro). ![PaymentsPro\_RequiresUsersUpgrade](https://productcart-kb.nsource.com/hs-fs/hubfs/PaymentsPro_RequiresUsersUpgrade.png?width=670&height=265&name=PaymentsPro_RequiresUsersUpgrade.png) #### 2. PayPal Payments Pro is a Legacy Service PayPal has announced[Payments Pro is legacy](https://developer.paypal.com/api/nvp-soap/paypal-payments-pro), and they are limiting support to their legacy services and recommending merchants to switch to newer and fully supported services they offer. Due to the above, it's best to look to newer supported versions of PayPal, or, different Gateway Integrations to continue taking credit card payments online without interruption.
