Do anyone have similar experience?
I would like to know the difference between the notify_url and return in Paypal integration. As my understanding, Paypal will pass the transaction detail to notify_url for further action, but what if I set both notify_url and return in the form, how do I completing the notify_url and the call the return from php script?
Best regards,
Kelvin.
The Return URL is where PayPal sends the buyer after they've completed everything on the PayPal pages.
In the case of Payments Standard that would typically happen after the payment is completed, and then the return URL may be used in conjunction with PDT (Payment Data Transfer) to pass data to the return URL so that you may display it for the buyer as a thank you / receipt page. With API calls the ReturnURL redirection from PayPal generally happens prior to the payment being completed.
Notify URL is used with IPN (Instant Payment Notification) which is very similar to PDT except that IPN notifications are sent as a "silent POST" to your listener script on your server. These notifications will be sent in real-time with all transactions on your PayPal account so you can automate procedures for things like payments, refunds, disputes, cleared e-checks, etc.

How can i use IPN for PAYPAL PAYMENT ADVANCED?
I am working on a website where the payment system needs to be changed from paypal standard to paypal payment advanced. The transaction type for the website is almost always a 'Authorization'. So, we capture payment later when we ship the item.
The problem i am facing is finding a way to receive IPN or something equivalent for it to update the system if transaction has been captured. I used to use the CUSTOM and notify_url for reciving IPN in the old system. But I dont know what to use for PAYPAL ADVANCED.
note: i am using OpenCart, PHP and layout A for paypal advanced.
Im haing a problem iv been researching for weeks now on the paypal API but i just can't figer how to do this.
I need there to be a button on my website which then it goes to paypal.
Once you have paid the chosen amount it goes to a php page which updates the database though php.
You have to turn on paypal ipn in your paypal preferences. Once paypal has the money it sends you a transaction back to your server. In the script that accepts the transaction you can have it update your tables.
Documentation : https://www.x.com/sites/default/files/ipnguide.pdf
generally you pass a notify_url parameter with the request, and set up a page which handles and validates IPN notifications, and PayPal will send requests to that page to notify you when payments/refunds/etc. go through. That IPN handler page would then be the correct place to update the database to mark orders as having been paid.
i found a tutorial here: http://net.tutsplus.com/tutorials/php/using-paypals-instant-payment-notification-with-php/
I found more suitable the PayPal NVP API instead of tradional IPN (Instant Payment Method)
You can find several code examples for PHP (including very similar to your problem and more advanced) in the library code for NVP samples
I am new to sandbox and paypal payment gateway. I am using paypal adaptive payment to pay amount to two people at a time. My current code works perfectly. I am using the paypal generated code. I just want to know that is it possible that when the payment is made successfully can I make that entry to my database. I have my php code, but where do I need to write this?
Thanks in advance(plzz no down votes)
You should wait for the IPN message that contain details about the payment status
https://www.paypal.com/ipn
You need to define the url of the php script that listen for those messages in your paypal account. There are some php examples on how to implement it.
First time I am trying paypal adaptive payments. Everything is working fine, I tested on sandbox and it works well. Now I need to track whether the payment was successful or not? I was looking into IPN. I saw it and I think it will be perfect to make the success call.
Currently I am using the adaptive code generated by paypal, I am just confused where to call the IPN function(I am using this IPN script)
Can any one help with this?
You don't call the IPN function, PayPal calls your IPN script at a pre-specified URL when it wants to notify you of a payment.
(In soviet PayPal, function calls you!)
I am trying to get the transaction info of paypal transaction that is passed to our website when customer is redirected to our website.
I turned auto-return and pdt in my sandbox paypal account setting. I posted a sample transaction to paypal and it replied to my return url with tx appended.
As found in some docs I did a curl req to https://www.paypal.com/cgi-bin/webscr and tried to get information by passing the req values as follows:
a.) tx = same one received from paypal
b.) at = pdt code given by paypal while turning pdt on
c.) cmd= "_notify-synch"
but in result i get String(0) "".
What I am missing?
I'd highly suggest looking into using PayPal Instant Payment Notifications (IPN).
PayPal IPN allows you to (asynchronously) process order information while not having to depend on the buyer to return to your website to complete the order.
You can use IPN by setting up a script which receives this (POST) data from PayPal. In addition, you must include the following code in your button and/or API call(s):
For Website Payments Standard (where "xxxxxxxx" is the full URL to your IPN script):
input type="hidden" name="notify_url" value="xxxxxxxx"
For Express Checkout:
Include NOTIFYURL=xxxxxxxx in your SetExpressCheckout and DoExpressCheckoutPayment API call
For Website Payments Pro
Include NOTIFYURL=xxxxxxxx in your DoDirectPayment API call
You can find sample code, documentation and further information on PayPal IPN at https://www.paypal.com/ipn
Additionally, here's an article with additional steps on verifying the authenticity of IPN messages at https://www.x.com/developers/community/blogs/ppmtsrobertg/securing-your-instant-payment-notification-ipn-script
