The GitHub repository https://github.com/WadeShuler/PHP-PayPal-IPN has been deleted, so a composer install will fail if you have this dependency. I have uploaded a copy of the vendor/wadeshuler/php-paypal-ipn directory here so you can un-break your dependencies. This is only version 2.5.0 sorry! This is not a fork of the original repo. This is a copy of the directory from vendor.

These instructions fixed it for me:

  • Remove wadeshuler/php-paypal-ipn from the requires in composer.json.
  • Manually remove the section "name": "wadeshuler/php-paypal-ipn", from composer.lock.
  • Edit composer.json and add:
    "repositories": [
            "type": "vcs",
            "url": "https://github.com/antriver/wadeshuler-php-paypal-ipn"
  • Re-add the package:
COMPOSER_MEMORY_LIMIT=-1 composer require wadeshuler/php-paypal-ipn:2.5.0

You might not need the COMPOSER_MEMORY_LIMIT or even the first 2 steps but I was having out memory issues when running this, which may have been unrelated.

!!! I have no idea if this package still even works. I have only done this to fix a broken composer install. Use entirely at your own risk.

Original README follows.


Forked from: https://github.com/Quixotix/PHP-PayPal-IPN/

Forked from the great Quixotix PayPal IPN script, which is no longer maintained. From now on, you should use this repo instead, as I have adddressed it's issues and brought it back to life.

This fork fixes the known issues with the original repo, as well as updates the code according to PayPal's documentation, and today's standards.

NOTICE: The SSLv3 issue is fixed!

This has been fixed and works out of the box, the old Quixotix repo no longer works!

PLEASE NOTE: I am still in the works of cleaning this package up. These docs still have remnants of the original repo, so please bare with me. I am not trying to remove his name, and I give Quixotix full credit for his original work. His repo just hasn't been updated since 2012, and it's now 2015 and it isn't maintained anymore. If there is anything I need to do, or reword, to ensure he is appropriately credited just let me know.

@TODO Recode to follow best practices (camelCase, etc).

@TODO Finish updating Readme and Documentation.

@TODO Add security to verify payment status is completed and owner's PayPal email address.

@TODO Update examples

Requires: PHP >= 5.3

A PayPal Instant Payment Notification (IPN) class for PHP >= 5.3 (if you aren't on at least 5.3, then I can't help you! I will not support dead versions!)

Use the IPNListener class in your PHP IPN script to handle the encoding of POST data, post back to PayPal, and parsing of the response from PayPal.

Install with Composer

Composer is now supported!

Packagist: https://packagist.org/packages/wadeshuler/php-paypal-ipn


    "require": {
        "wadeshuler/php-paypal-ipn": "*"


  • Switch between live and sandbox by setting the use_sandbox property.
  • Supports both secure SSL and plain HTTP transactions by setting the use_ssl property (SSL is recommended).
  • Supports both cURL and fsockopen network libraries by setting the use_curl property (cURL is recommended).
  • Verifies an HTTP "200" response status code from the PayPal server.
  • Get detailed plain text reports of the entire IPN using the getTextReport() method for use in emails and logs to administrators.
  • Throws various exceptions to differentiate between common errors in code or server configuration versus invalid IPN responses.

Getting Started

This code is intended for web developers. You should understand how the IPN process works conceptually and you should understand when and why you would be using IPN. Reading the PayPal Instant Payment Notification Guide is a good place to start.

You should also have a PayPal Sandbox Account with a test buyer account and a test seller account. When logged into your sandbox account there is an IPN simulator under the 'Test Tools' menu which you can used to test your IPN listener.

Once you have your sandbox account setup, you simply create a PHP script that will be your IPN listener. In that script, use the IPNListener() class as shown below. For a more thoroughly documented example, take a look at the example/ipn.php script in the source code.



$listener = new \WadeShuler\PhpPaypalIpn\IpnListener();
$listener->use_sandbox = true;

if ($verified = $listener->processIpn())
    // Valid IPN
        1. Check that $_POST['payment_status'] is "Completed"
        2. Check that $_POST['txn_id'] has not been previously processed
        3. Check that $_POST['receiver_email'] is your Primary PayPal email
        4. Check that $_POST['payment_amount'] and $_POST['payment_currency'] are correct

} else {

    // Invalid IPN




Documentation has not been generated yet, but, there are phpDocumentor style docstrings (comments) throughout ipnlistener.php which explain the important public properties and methods.

I have also written a more in-depth IPN tutorial on my blog: PayPal IPN with PHP

Example Report

Here is an example of a report returned by the getTextReport() method. Create your own reports by extending the IpnListener() class or by accessing the data directly in your ipn script.
