According to the docs, there are 2 ways to set up IPNs.
What is unclear is if they are mutually exclusive or not. What happens if both are provided.
https://developer.paypal.com/docs/classic/ipn/integration-guide/IPNSetup/#setting-up-ipn-notificatio...
So, let's assume I've followed the guide and I've enabled the IPN in my PayPal account.
And in my HTML form on my website, I have the following
<input type="@htmlType" name="notify_url" value="someOtherUrl" />
For clarity, this means both ways of getting the IPN are enabled, but the value (return URL) are different.
What happens now? Does one take priority?
