How do I link 2 Paypal IPN URLs to a single PayPal account?
You are only allowed to put 1 IPN URL within your PayPal account, but we only use this specific link in the case where a customer sends you payment outside of ChannelAdvisor. When this happens, we are notified through this link and we send you an email letting you know that further action on your part may be required for this order since it took place outside of ChannelAdvisor. During checkout we actually send paypal a checkout specific IPN URL to notify us about the payment for that specific order. This will vary automatically from account to account, so there isn’t any setup required from you for this.
