I'm using PayPal Payments Standard to generate links that attendees at a silent auction can use to submit payment for their winnings. The items are entered by auction staff, then my app systematically generates cart upload links and sends them to the winning bidders. Testing in my sandbox, payments aren't getting processed. Currently the links are pointing to my facilitator sandbox account. The payment page and cart info loads appropriately. However, if I try to check out using a credit card, I get the error "Things don't appear to be working at the moment. Please try again later." If I log in using my buyer sandbox account, nothing happens when I click "Pay Now"; the "Processing" image spins for a couple seconds, then the same payment page reloads. Here's a sample of my link URL structure: https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_cart&upload=1&business=MKNJSUCCMFE8U&lc=US&no_note=1&no_shipping=1&notify_url=https%3a%2f%2fbpsfallfete2018%2eherokuapp%2ecom%2fpaypal%2f&invoice=1&item_name_1=Test+Item+1&amount_1=3&item_name_2=Test+Item+3&amount_2=5&item_name_3=Test+Item+6&amount_3=1&first_name=Test&last_name=Bidder1 Is there something I'm doing wrong? I'd like to confirm this is working in the sandbox before switching to our production account. Thanks, Mike
