I have a service used by some PayPal merchants who sell downloadable products to automatically manage the download. I use a "notify" script to receive the IPN order data and send the customer an email with a download link. I also use a "return" script so that the customer can download immediately after payment. I use the "rm=2" option for the "return" which is supposed to post the same data to the script as the "notify" script, and in fact it is working for all except one account, and that account had been working until recently. (I don't know if the user accidentally changed a configuration setting in PayPal.)
Instead of the IPN data, I'm receiving a GET request with the following query string:
PayerID=WT4JZSFG2FW9U&token=0WU827005R158274M&useraction=commit&rm=2&mfid=1689315936747_f53577586934e&ssrt=1689315937327&rcache=1&cookieBannerVariant=hidden&country.x=GB%2CGB&locale.x=en_GB%2Cen_GB
Does anyone recognize that type of request?
