Hi Michael, At least I am happy to find someone with exactly the same problem! I have at my site a PayPal "Buy Now"-button, where I have added some code to the button-form with the member-id of my logged-in member in the optional parameters "on1" and "os1", to be able to retrieve the member in my database. This member-id was always available in the payment confirmation e-mail and it has been working fine for many years already. Needless to say that the code did not change recently. At first I hoped the problem was temporary, it started on July 11, and July 14 there was one single payment confirmation e-mail where the optional parameters were suddenly available for once, but ever since it is not working any more. Since then I have to try and match the payment by e-mailaddress, but this is often different from the e-mailaddress that my customer used to register at my site. (If different, this match can take me an hour, if possible at all, with my almost 20.000 registered members.) There is a list at https://developer.paypal.com/api/nvp-soap/paypal-payments-standard/integration-guide/Appx-websitestandard-htmlvariables/ with deprecated HTML-variables, but on0, os0, on1, os1 etc. are not in this list. Another change since July 11 is that my PayPal app does not receive push-notifications any more, after a payment has been made. This was always very handy, because I have a particular ringtone in the app that tells me that I should do what the customer has payed for. Again needless to say that I did not change any setting. I have reported the problem to PayPal Customer support on July 16; they answered the same day that the question was too technical for them and told me to contact Merchant Technical Support at https://www.paypal-support.com/, which I did. This MTS replied "Unfortunately, my team and I do not have access to the tools available to troubleshoot this issue." and referred back to Customer Support, by clicking "Contact Us" on the https://www.paypal.com/smarthelp/contact-us/ site. At this PayPal page, clicking "Contact Us" always opens the PayPal Assistent pop-up screen, that will of course take you nowhere. Then I made a half hour phone-call with a very friendly helpdesk employee, who admitted that MTS should have said they just cannot help, instead of referring back to Customer Support and he could only advise to try the PayPal Community(!!!) So here we are. (Unfortunately I do not know of any alternative payment method for international small payments.) Should I find a solution, I will of course publish it here. (If it is not yet solved by PayPal, or maybe someone else came up with a solution.)
