Hello @troussel
The previous IPN endpoint was only used by the PayPal Checkout Gateway plugin (or the Standard integration) and can be disregarded/deleted if you no longer use any of the two integrations: https://www.paypal.com/us/smarthelp/article/how-do-i-stop-receiving-instant-payment-notifications-(ipns)-faq426
PayPal Payments does not use PayPal IPN but instead transmits events via webhooks. This works similar to IPN, but better and so you don’t need to enter a specific URL anywhere as everything is automatically configured by the plugin.
We added an interface to manage the webhooks from within the plugin on the “Webhooks Status” page:
The webhook registration happens automatically when connecting your account, but if you have any issues with the communication to PayPal, we recommend clicking the “Resubscribe” button and after the site is reloaded, the “Simulate” to verify that the webhooks are received.
So there is no?need to worry about PayPal IPN anymore when using PayPal Payments as?the new integration?uses the latest PayPal JavaScript SDK and REST API integration.
It’s worth mentioning that there are cases where PayPal sends these emails out even when the IPN is actually working. But when you removed the previous plugin, the endpoint no longer exists and so it would fail.
For any further questions, feel free to reach out anytime.
Kind regards,
Joost
