PayPal IPN has a limitation where you are only able to provide a single URL to receive the IPN notifications sent when transactions hit your PayPal account. All too often merchants are selling products and services through multiple sources, and each of these sources may utilize PayPal IPN to process orders accordingly. What if you have multiple tools, though, with each asking you to setup your PayPal account to send IPN notifications to their URL? That’s where the PayPal IPN Forwarder comes into play!
How Does the PayPal IPN Forwarder Work?
In your PayPal account profile you will configure IPN so that it points to the URL provided by the PayPal IPN Forwarder. This way all of the IPNs that PayPal sends out will be logged in your admin panel, and with the PayPal IPN Forwarder activated it will automatically send that same IPN data out to as many additional listeners as you have configured in the plugin.
All of the IPN data that gets sent out will verify against PayPal’s servers the same way it would normally, and they will all be hit immediately when the transaction occurs just as if PayPal was sending it directly to that URL. here is a sample wordpres plugin ([login to view URL]) I need to know how much cost would it be for a wordpress plugin like this but I would prefer a web app with this functionality instead because I can reach more user than a wordpress plugin so I need the cost for the web app as well and see which is more affordable...
