paypal recurring payments and ipn management

[daniele_gusmini]

HI,

I'm trying to integrate recurring payments with PayPal into one of my projects.
I found this code which seems to work correctly for what I need https://www.codexworld.com/paypal-subscriptions-payment-gateway-integration-php/

However, I don't understand how to manage PayPal notifications in these cases:
- managing of the renewal, i.e. whether the renewal payment was successful or not
- if a customer who has signed up for periodic payments cancels the subscription from the PayPal portal

I already save the activation, expiration date and others info at the time of the first payment (see  https://ibb.co/2qyKncX)
What I don't understand is how PayPal sends the renewal notification (ipn).

From what I have read, but I don't understand much, PayPal sends a notification to the site via ipn every time the weekly/monthly fee is deducted from the customer's account based on the plan subscribed to. But I didn't understand where it sends it and how I can process the data to update the customer's subscription.

Thanks a lot

Daniele

Good day @daniele_gusmini,

Thank you for posting to the PayPal community.

Please get in touch with your website developer or the support of your third-party platform to refer to guide links to implement payment notification service. 

https://developer.paypal.com/docs/api-basics/notifications

• If your website is built via NVP/SOAP API integration, please use the Instant Payment Notification(IPN) service to receive payment notifications.

           Guide link - https://developer.paypal.com/docs/api-basics/notifications/ipn/

• If your website is built via REST API integration, please use Webhooks event notification to get the payment notifications.
