We’re going to discuss then extremely briefly and…

I will include a link to that post here once its up. This is a more general post so perfectly usable in PHP without a framework.

How to check your paypal account age

How to check your paypal account age

Paypal have done a decent job of hiding your own info from you. You may want to know when you opened your paypal account (as I recently did as part of a vetting process).

This one is more of a documentation to myself, but the new location API may be useful to you, and you may have additional sources of data! The idea is simple.
