I'm currently using PayPal buttons on a site. When the transaction completes, my backend system gets an IPN with the details to process and dispatch the purchased item.
The javascript-driven express checkout looks nice and fancy, but I'm confused by the mixed statements and documentation. Do I need to implement WebHooks to achieve the same with the newer express checkout? Or do I still receive IPNs?
I also have subscription buttons that won't use the express checkout yet. So I need to know if I can use IPNs to process both purchase types, or if JS-express checkouts only send webhooks and not IPNs.
I want to avoid signing up to webhooks and then receiving both webhooks and IPNs for the same order.
Found out I can actually test this in the sandbox by creating a sandbox merchant account, logging in on sandbox.paypal.com, and setting up IPNs there.
Yes, IPNs are still sent for the Javascript Express Checkout functionality. Webhooks are optional.

I'm unable to find documentation by PayPal about how it handles webhooks for payouts. Are payouts treated the same as payments, so that a completed payout will initiate a payment completed webhook? In general, do payments and payouts translate to each other doing webhooks; or are there intricacies and gotchas someone from the paypal team could explain to me?
In a webhook perspective, the payouts transactions and sale transactions are not exactly the same thing. The payout event will be added into the webhooks supported event type list but not yet at this moment.
https://developer.paypal.com/webapps/developer/docs/integration/direct/rest-webhooks-overview/#event-type-support
So the classic IPN will still be your consideration of handling the "call-backs", for payouts and even other transaction types under RESTful API
Steps To work on payout:
go to paypal developers account and login using business account
Create new app and get client, secret etc
create some personal accounts.
Go to https://github.com/paypal/Payouts-PHP-SDK to get sample code. Update your credentials and it will work.
If you want a running code, go to https://www.voizacinc.com/ and submit inquiry. You will get working code.
I'm overflowed a little bit reading Introducing IPN https://developer.paypal.com/webapps/developer/docs/classic/ipn/integration-guide/IPNIntro/:
at the begiining: "IPN is a message service that PayPal uses to notify you about events, such as: Instant payments, including Express Checkout, ..."
at the end: "If you are using Express Checkout ... You should not use IPN for this purpose."
Perhaps anybody knows correct option - to use or not to use IPN with Expres Checkout?
IPN can be used for purposes such as:
Trigger order fulfillment or enable media downloads
Update a list of customers
Update accounting records
Create specialized "to do" lists
If you are using Express Checkout or Direct Payment, the PayPal API notifies you of the status and details of the transaction immediately and automatically. In either case, you can immediately show your customer the payment information returned by PayPal . You should not use IPN for this purpose.
This means that you need not use IPN for knowing the transaction status , because once "dodirectpayment" is completed, you will know the transaction status immediately.
Yes, if you want to use IPN for backoffice operations such as updating your own database, emailing your customers upon purchase and offers etc. you can use IPN with Express Checkout.
When I use the Checkout express API calls do I need to have an IPN listener to confirm payment?
Some places give the idea that once I receive a response from DoExpressCheckoutPayment the payment has gone through and I can take action - update the database etc.
Some posts here http://www.zen-cart.com/showthread.php?72304-Paypal-IPN-and-Express-Checkout suggests that IPN is old or outdated.
You could use either or, or you could use both. The IPN will will update your system if the buyer pays with an echeck once it clears, just as it will update your system of refunds and chargebacks. The respone from the Express Checkout API call wont do this. You would have to check manually.
I'm trying to use paypal ipn on my website. I am using sandbox to debug it...
I noticed sometimes I get values on payment_status like pending ...
My question is, do I get a response again from paypal ipn when this payment becomes complete?
Yes you do. That is the reason why you should implement logic in your code to cope for multiple messages relating to the same transaction.
From paypal site: https://cms.paypal.com/es/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_testing_SBOverview
"The PayPal Sandbox is a self-contained environment within which you can prototype and test PayPal features and APIs. The PayPal Sandbox is an almost identical copy of the live PayPal website"
Comparison table in the link above does mention some scenarios like Fraud detection are not enabled in sandbox.
Other than these, it should be safer to assume that features of live are same in sandbox ( like receiving IPN after status change from pending to complete etc).
I have downloaded sample code from paypal to allow me to use parallel payments via their sandbox accounts. When I run parallel.php, I get redirected to paypal's sandbox login page.
How am I supposed to know "server side" that the payment has been made successfully, so I can update my database records?
I believe you have to work with PayPals IPN system. This will basically send a confirmation to your server that tells you it has gone through.
https://www.paypal.com/ipn
Paypal lets you register a notification url which is part of the IPN (instant payment notification IIRC) system. So if someone pays by a delayed payment (such as a bank transfer) the transaction will update days later. You need to have an application (web page) on your server that can be called by Paypal with transaction details to update a payment.
You'll need to create an initial transaction record in your system when paypal redirects back to you so refer to their documentation for that. I'd also recommend looking at either OSCommerce or Zen cart for an idea of how they do it as they support the same kind of thing.
