One of our goals at Redfame and IFP3 is to provide you with a “set it and forget it” environment for you to run your website. As web technology evolves and changes we handle all the aspects of keeping up with those changes. We do our absolute best to let you focus only on what you put on your website and how it looks. However, every now and then, there are some technical changes that are beyond our control and we need you to do a few changes that are outside of our system. This is one of those situations. PayPal has made a technical update within their platform that you, as the account owner, need to update in order for your shopping cart checkout to continue functioning. Why? PayPal has made a recent update in the name of providing a more secure checkout experience that requires the IPN (Instant Payment Notification) URL be hosted on a secure site as well. Technically speaking, PayPal is upgrading the certificate for www.paypal.com to SHA-256. This endpoint is also used by merchants using the Instant Payment Notification (IPN) product. This upgrade is being done to align to the industry security standard. What do I do? As it is not currently feasible to get a security certificate for every domain using the Redframe/IFP3 platform, we have engineered a solution to meet your needs. Simply log into your Paypal account and update the IPN URL to https://admin.redframe.com/orders/paypal_ipn.cfm . That URL will handle everything from there. If you need a refresher on how to update your PayPal IPN please refer to this Redframe Help Desk article. Please contact our Support Team if you need any further explanation or help.
