LaterPay needs to authenticate your domain(s) within your LaterPay Merchant Account.
There are two reasons -- one technical and the other business-related -- why LaterPay must authenticate your domain(s) before including your websites.
First, LaterPay authenticates your site by checking the domain of each incoming request to ensure that it is your site. Our software only knows about your domain, or a testing or staging domain, if you explicitly list it.
Second, LaterPay needs to know what your domains are to periodically check that they are meeting our Terms and Conditions.
