Paypal Sandbox Test Tool IPN Simulator in Localhost - paypal-ipn

Question

How to use Instant Payment Notification Simulator in local machine? What will be provided in IPN handler URL? I don't have access to our router.
Thanks

Answer 1

You can test on localhost using ngrok.
Simply run ngrok locally then paste test url that ngrok gives you (something like http://1bc7d09d.ngrok.com/)
It provides a tunnel to your localhost.

Answer 2

Paypal's IPN simulator will not work with localhost. However, you can simulate the simulator :-). To do this you need to install a browser plugin/extension such as poster for firefox or Advanced Rest Client for google chrome.
Open the app and put in your url you are listening on for IPN responses:
http://localhost/ipn
Put the following as your POST data and submit the request:
residence_country=US&invoice=abc1234&address_city=San+Jose&first_name=John&payer_id=TESTBUYERID01&mc_fee=0.44&txn_id=421462822&receiver_email=seller%40paypalsandbox.com&custom=xyz123+CUSTOMHASH&payment_date=12%3A40%3A25+27+Aug+2013+PDT&address_country_code=US&address_zip=95131&item_name1=something&mc_handling=2.06&mc_handling1=1.67&tax=2.02&address_name=John+Smith&last_name=Smith&receiver_id=seller%40paypalsandbox.com&verify_sign=AFcWxV21C7fd0v3bYYYRCpSSRl31AgAAjEU7A5rthY2aP4j1jOIrjuGx&address_country=United+States&payment_status=Completed&address_status=confirmed&business=seller%40paypalsandbox.com&payer_email=buyer%40paypalsandbox.com&notify_version=2.4&txn_type=cart&test_ipn=1&payer_status=unverified&mc_currency=USD&mc_gross=12.34&mc_shipping=3.02&mc_shipping1=1.02&item_number1=AK-1234&address_state=CA&mc_gross1=9.34&payment_type=instant&address_street=123%2C+any+street
UPDATE: I just started using another option that is easier, https://localtunnel.me. To install and run the module do the following. It will show your public URL. All requests to that public URL will be forwarded to your localhost.
npm install -g localtunnel
lt --port 80

Answer 3

You cannot test IPN on your localhost, as IPN is all about PayPal's server initiating a server-side POST to a URL you define.
As a result, your IPN script must be accessible by the outside world (or you can use a tunnel such as ngrok.me/localtunnel.me).

Answer 4

You can simulate PayPal's IPN post by running the script below I made on your localhost (you'll need curl installed). As long as your listener is pointed to the sandbox it should validate. Change your listener to the live paypal and it should fail to validate.
<?php
// SIMULATE PAYPAL IPN LOCALLY
//
// Sometimes you need to test on your local host and this can be difficult due
// to IP routing issues. Use this code on your local machine to simulate the
// same process that the sandbox IPN simulator does when posting to your URL.
//
// Run this code in command line or via the browser. It will post IPN data just
// like Paypal would. If the code you've written to process your IPN data
// posts back to the sandbox, it should come back as valid.
// Put the full url to test in $paypal_url, include file extensions if necessary
$paypal_url = 'http://localhost/paypal_ipn/process'; // IPN listener to test
//example posted data from paypal IPN
$test = 'residence_country=US&invoice=abc1234&address_city=San+Jose&first_name=John&payer_id=TESTBUYERID01&mc_fee=0.44&txn_id=421462822&receiver_email=seller%40paypalsandbox.com&custom=xyz123+CUSTOMHASH&payment_date=12%3A40%3A25+27+Aug+2013+PDT&address_country_code=US&address_zip=95131&item_name1=something&mc_handling=2.06&mc_handling1=1.67&tax=2.02&address_name=John+Smith&last_name=Smith&receiver_id=seller%40paypalsandbox.com&verify_sign=AFcWxV21C7fd0v3bYYYRCpSSRl31AgAAjEU7A5rthY2aP4j1jOIrjuGx&address_country=United+States&payment_status=Completed&address_status=confirmed&business=seller%40paypalsandbox.com&payer_email=buyer%40paypalsandbox.com&notify_version=2.4&txn_type=cart&test_ipn=1&payer_status=unverified&mc_currency=USD&mc_gross=12.34&mc_shipping=3.02&mc_shipping1=1.02&item_number1=AK-1234&address_state=CA&mc_gross1=9.34&payment_type=instant&address_street=123%2C+any+street';

Answer 5

I do test on localhost. You can use a service like dyn.com or noip.com or point a subdomain to your local address if it's static.

Answer 6

/ngrok http -host-header=yourwebsite.com 80
will tunnel to localhost with the right host header
