I have setup webhook and IPNs (Instanst Payment Notifications) with in paypal. It is my understanding that if I select ' * All Events ' within the webhook setup, that I would receive a webhook for any transaction that occurred in paypal - including ebay sales that were paid through paypal.
Since setting up the webhook, I have had a few sales go through paypal, but 0 webhook notifications were receivied.
Am I missing something about paypal webhooks?
The most effective way before you start receiving payments is usually by testing your webhook events and if they're going through, follow the below step
Set up your development environment.
Configure a webhook listener.
Validate your listener configuration with mock webhook events.
Subscribe to events.
Verify event notifications.

I'm integrating PayPal payment gateway into my application. I'm using the PayPal REST API's. I'm able to authorize the request and webhook. Also, API and webhooks are working fine for me. The only thing about I'm little confused that which event and sequences of events will be if subscription payment failed?
For subscriptions, the only event you need to act on is PAYMENT.SALE.COMPLETED. When you receive this event, update the profile's valid date through the next cycle (e.g. 1 month in the future). If you don't receive a new PAYMENT.SALE.COMPLETED in time, the subscription has lapsed.
When creating the subscription you can set a custom_id which is useful for reconcilliation.
I am building the system to listen to the Payment changes in PayPal for that I research and recommended using Webhooks over the IPN.
As of now, I can able to create an app and add webhooks with event subscribers. Also, with the webhook simulator I am getting notified correctly but with the actual Payment made in the sandbox does not trigger anything to the listener.
I have verified the correct business account linked with credentials as well.
Everything is working perfectly except the Webhooks triggering from PayPal.
Also, as noting is triggering I do not have debug id as well.
If you have not registered any webhook listeners for any of your REST Apps (either sandbox or live), PayPal will not send any webhooks because it does not know which ones to send events for, or where to send them.
To register webhooks for an app, either:
Find the app for the correct sandbox account in My Apps and Credentials (or create one), and Add Webhook
Do so via using thewebhooks API, with the correct REST App client id and secret for authentication
Until you register a listener URL for event(s), no webhooks will be sent.
I have been using Pay Pal for payments from our website for many years without problems.
We currently use Pay Pal buttons to redirect to Pay Pal's website for the payment, and have it return to our website to record the payment.
Now we are trying to configure webhooks in Pay Pal to have it notify our server of payments. The goal is to have auto renewing subscriptions that call the webhook every month when Pay Pal automatically processes the payment.
So I setup the webhooks on,
https://developer.paypal.com/
I setup the webhooks for both the sandbox and live account, and verified it can call the webhook successfully through their webhook simulator.
However, when any payment is made through our website the webhooks are never called?
I've tried everything, but they are never called.
Are the webhooks only called if you make the payment through the Pay Pal API, or are they also called if a payment is made directly, or through a Pay Pal button?
Do they get called for auto-renewing subscriptions?
Okay, so now I know that said you did set up the webhooks. However, I am still going to include doing that in my answer anyway.
Step 1: Creating The PayPal Application
Visit URL: https://developer.paypal.com/developer/applications/ and
click 'create app'
Give your Application some name and move forward.
Step 2: Adding/Managing WebHooks For Your Application
After creating the app, you will be presented with this screen.
Scroll a bit down and click 'Add Webhook'.
Add your desired webhooks (subscription webhooks are here). If you are not sure. Just choose 'All events' (the first option) for the time being. Also, make sure you add a Webhook URL.
Step 3: Listening for WebHooks
Webhook Details:
https://developer.paypal.com/docs/api-basics/notifications/webhooks/event-names/#sales
The webhook you need to listen for auto-renewing subscriptions is: PAYMENT.SALE.COMPLETED
Step 4: Verifying you are getting the Callbacks
You can visit:
https://developer.paypal.com/developer/dashboard/webhooks/live to see
all the webhooks that were fired by PayPal (only stores up to 30 days).
Personally, I would try to log everything that I receive at my
endpoint and compare my log with PayPal's log.
Step 4: Validating the Callbacks
Furthermore, you can also visit:
https://developer.paypal.com/docs/api-basics/notifications/webhooks/rest/#to-use-the-paypal-rest-sdks-to-verify-event-notifications
to get the sample code(s) to validate the callback (webhooks) once you receive
them.
Please understand the distinction as i have quoted from the below sources.
The PayPal REST APIs use webhooks for event notification.

The Paypal BuyButton triggers IPN
I haven't tested in live, but currently I have a webhook subscribed to the following events
Billing subscription cancelled
Billing subscription created
Billing subscription re-activated
Billing subscription suspended
Billing subscription updated
I'm receiving Webhook events for CREATED but nothing is being sent when a user cancels the subscription from their PayPal dashboard.
Is this expected behavior? is there another event I should be subscribe to to capture that user action?
Is there a debug id that you can share so we can trouble shoot?
Thanks,
Usha
From Paypal support (I still don't understand why the BILLING.SUBSCRIPTION.CANCELLED doesn't fire when a user cancels from their dashboard, similar issue here: BILLING.SUBSCRIPTION.CANCELLED does not fire upon user action?)
"But surely users subscribing via the button is the most common method of subscribing (how else would they subscribe?). The IPN route seems like a completely non-developer-friendly one (seeing as there isn't even simulator events for it)"
If you integrate a solution which is not based on our REST API's and want to receive HTTP notifications, you need to use instant payment notification (IPN). The IPN simulator may not provide a method of simulating the events, but you can create subscriptions in our sandbox environment and setup a sandbox business account with IPN and test cancelling the subscriptions, which will generate an IPN for the cancellation. We have a sandbox testing guide available here if you're not familiar with that environment and want to get started.
"So why would webhooks ONLY fire for API-based subscriptions (and why would a business website subscribe users using the API rather than the simple button)? What is the logic behind this?"
It depends on the integration and needs of the individual business. Some businesses only use our REST-based API solutions for their complete integration, from checkout payments to subscriptions and logically, this makes sense to them to only have to use one set of API's for their complete integration. Other business only want / need a more simple solution such as using buttons and as these are legacy solutions which are not REST-based, they use our legacy HTTP notification service which is instant payment notification (IPN).
Could anybody please tell me what happen if payment is made on PayPal but IPN is not triggered because server is down on merchant website.
How paypal will check and authorize the payment on merchant server?
IPN is an (optional) notification service, it isn't related to the transaction (aka "checkout flow", "payment flow") per se. It notifies the receiver (of the IPN message) of event(s) in transactions that occur at Paypal.
Instant Payment Notification
Instant Payment Notification (IPN) is a message service that automatically notifies merchants of events related to PayPal transactions. Merchants can use it to automate back-office and administrative functions, like automatically fulfilling orders and providing customers with order status.
...
Using IPN in your checkout flow
Although PayPal usually processes IPN messages immediately, IPN is not synchronized with actions on your website. Internet connectivity
is not always 100% reliable and IPN messages can be lost or delayed.
The IPN service automatically resends messages until the listener
acknowledges them. The service resends messages for up to 4 days.
Because IPN is not a real-time service, your checkout flow should not
wait for the IPN message before it is allowed to complete. If the
checkout flow is dependent on receiving an IPN message, processing can
be delayed by system load or other reasons. You should configure your
checkout flow to handle a possible delay.
