I'm using WooCommerce version 3.3.5 and I'm trying to get the IPN to work so that my orders get updated.
I added https://powertrainexpo.com/?wc-api=WC_Gateway_Paypal as my notification URL in PayPal.
I'm currently getting a 500 error "PayPal IPN Request Failure" when the order is processed.
What are we doing wrong or what do I have to do to fix this problem.
Thanks in Advance
