Hi
For the last 13 years, I used to have some PayPal buttons on my website with IPN (notifications of payment) back to my server. It worked fine, until 1 or 2 years ago. Today I do not get anymore IPNs.
Today I try to fix it, but the online documentation is not very clear.
I have read the basic integration doc online (https://developer.paypal.com/docs/checkout/integrate) and I have tried to make a test. It doesn't work at all. It's all about Javascript and some variable are not defined, like the paypal variable.
Here is the code for instance :
<body>
<div id="paypal-button-container"></div>
<script>
paypal.Buttons().render('#paypal-button-container');
</script>
</body>
Safari tells me that paypal variable is not known. How can I know if this has been defined in Javascript PayPal source ? I can't.
Server side :
a function is defined : function handleRequest(request, response)
What are the variable request and response ??? Where do they come from ? How do I get them ?
Generally, the IPN is received by a script that is defined into the client button code. And I read the IPN data (which are POST data) in this file.
I really don't understand how this works.
Can you help ?
