I'm the developer who has implemented a simple shopping cart for a client. I'm using a simple 'Pay Now' button. It's been working for over a decade now (with minor changes along the way). It was working up until April 13, 2019 but since then, customers have been getting the message:
Things don't appear to be working at the moment. Please try again later.
The cart always has 1 item in it. Here's a typical form that I submit to PayPal:
<form method="post" action="https://www.paypal.com/cgi-bin/webscr"/>
<input type="hidden" name="rm" value="2" />
<input type="hidden" name="cmd" value="_xclick" />
<input type="hidden" name="charset" value="utf-8" />
<input type="hidden" name="currency_code" value="CAD" />
<input type="hidden" name="quantity" value="1" />
<input type="hidden" name="business" value="my paypal email address" />
<input type="hidden" name="return" value="url to return to" />
<input type="hidden" name="cancel_return" value="url to cancel to" />
<input type="hidden" name="notify_url" value="IPN url" />
<input type="hidden" name="item_name" value="my order number" />
<input type="hidden" name="item_number" value="1234" />
<input type="hidden" name="custom" value="custom field here" />
<input type="hidden" name="amount" value="12.34" />
<input type="hidden" name="first_name" value="buyers firstname" />
<input type="hidden" name="last_name" value="buyers lastname" />
<input type="hidden" name="payer_email" value="the buyers email address" />
<input type="hidden" name="bn" value="PP-BuyNowBF:btn_paynowCC_LG.gif:NonHosted" />
<input type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_paynowCC_LG.gif" border="0" name="submit" alt="Make payments with PayPal - it's fast, free and secure!">
<img alt="" border="0" src="https://www.paypal.com/en_US/i/scr/pixel.gif" width="1" height="1">
</form>
Can anyone spot what's wrong? I haven't changed anything on my system so I'm assuming PayPal has made some change to their interface.
Thanks in advance.
