response is not coming for my return url

[znv51powt]

Hi! I work in the sandbox. I send to

https://svcs.sandbox.paypal.com/AdaptivePayments/Pay

I get answer from PayPal:

{"responseEnvelope":{"timestamp":"2016-10-20T21:47:50.360-07:00","ack":"Success","correlationId":"fdb13f9bae29f","build":"26220497"},"payKey":"AP-2AD23957S5267231P","paymentExecStatus":"CREATED"}

But PayPal don't send $_POST on my return url.

Why?

After making the call to the Pay API you need to use the PayKey you get back to redirect the user to PayPal so they can login and complete the payment.  

For example, I have this basic sample setup that runs the Pay request and dumps out the result:  http://paypal.angelleye.com/paypal-php-library/samples/Pay.php

You'll see it includes a RedirectURL, and if you copy/paste that URL in your browser address bar you'll see it sends you over to PayPal where you could complete the payment using a sandbox buyer account (assuming that the sandbox isn't down, which unfortunately is happening a lot lately.)

Until that redirect and completed checkout happens the payment doesn't occur.

Also, in your example you used CREATE instead of PAY or PAY_PRIMARY, so this will require a call to ExecutePayment API to process the payment even after the person signs in and approves it.

Hi! thank you. I redirect user on page for payment with payKey, he makes the payment and I don't get IPN-message.

Maybe URL for IPN HTTPS and not HTTP ?

[angelleye]

IPN with Adaptive Payments is a little different.  There is an app specific IPN that you would trigger using the ipnNotificationUrl parameter in the Pay request, or there is a transaction specific IPN that would be triggered by the receiver account's profile settings.

You could use one, the other, or both.  What is it exactly you're trying to do?

[znv51powt]

I use IPN url from the receiver account's profile settings. This url is HTTP, not HTTPS.

Troubleshooting IPN is an entirely different subject from this thread, and would be a pretty lengthy conversation in and of itself, but I can quickly provide this article I wrote a while back on how to test PayPal IPN.  If you follow all the steps there you should be able to find your problem.

Ok, thank you, I try it!

https://www.angelleye.com/test-paypal-ipn/  -  Server not found

I get empty $_POST on my returm url: https://pay4links.com/pay-pal/success

I try https://developer.paypal.com/developer/ipnSimulator: on url https://pay4links.com/pay-pal/success

and ! get this answer: IPN was not sent, and the handshake was not verified. Please review your information.

Help me!!!

Not sure why you'd be getting a server not found error.  That URL is definitely valid and active.  

You've got some sort of an error going on in your IPN script keeping it from completing.  Check your PHP error logs and you should details about what exactly is failing.  

That guide I linked to goes into more detail.  Give it another shot.

I just tested the script you are using and got a HTTP 400 which pretty much means the code you are using is not prepared to receive the IPN post:

"<h1>Bad Request (#400)</h1>"

Can you grab the sample code here and give it a go?
