Please make sure you have the correct access rights and the repository exists. ``` 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. --- PHP-PayPal-IPN ============== Forked from: https://github.com/Quixotix/PHP-PayPal-IPN/ Forked from the great Quixotix PayPal IPN script, which is no longer maintained.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 composer.json { "require": { "wadeshuler/php-paypal-ipn": "*" } } Features -------- * 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][1] is a good place to start. You should also have a [PayPal Sandbox Account][2] 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. [1]: https://cms.paypal.com/cms_content/US/en_US/files/developer/IPNGuide.pdf [2]: https://developer.paypal.com 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. 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 ------------- 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][3] [3]: http://www.micahcarrick.com/paypal-ipn-with-php.html 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. -------------------------------------------------------------------------------- [09/09/2011 8:35 AM] - https://www.sandbox.paypal.com/cgi-bin/webscr (curl) -------------------------------------------------------------------------------- HTTP/1.1 200 OK Date: Fri, 09 Sep 2011 13:35:39 GMT Server: Apache X-Frame-Options: SAMEORIGIN Set-Cookie: c9MWDuvPtT9GIMyPc3jwol1VSlO=Ch-NORlHUjlmbEm__KG9LupR4mfMfQTkx1QQ6hHDyc0RImWr88NY_ILeICENiwtVX3iw4jEnT1-1gccYjQafWrQCkDmiykNT8TeDUg7R7L0D9bQm47PTG8MafmrpyrUAxQfst0%7c_jG1ZL6CffJgwrC-stQeqni04tKaYSIZqyqhFU7tKnV520wiYOw0hwk5Ehrh3hLDvBxkpm%7cYTFdl0w0YpEqxu0D1jDTVTlEGXlmLs4wob2Glu9htpZkFV9O2aCyfQ4CvA2kLJmlI6YiXm%7c1315575340; domain=.paypal.com; path=/; Secure; HttpOnly Set-Cookie: cookie_check=yes; expires=Mon, 06-Sep-2021 13:35:40 GMT; domain=.paypal.com; path=/; Secure; HttpOnly Set-Cookie: navcmd=_notify-validate; domain=.paypal.com; path=/; Secure; HttpOnly Set-Cookie: navlns=0.0; expires=Thu, 04-Sep-2031 13:35:40 GMT; domain=.paypal.com; path=/; Secure; HttpOnly Set-Cookie: Apache=10.72.109.11.1315575339707456; path=/; expires=Sun, 01-Sep-41 13:35:39 GMT X-Cnection: close Transfer-Encoding: chunked Content-Type: text/html; charset=UTF-8 VERIFIED -------------------------------------------------------------------------------- test_ipn 1 payment_type instant payment_date 06:34:51 Sep 09, 2011 PDT payment_status Completed address_status confirmed payer_status verified first_name John last_name Smith payer_email buyer@paypalsandbox.com payer_id TESTBUYERID01 address_name John Smith address_country United States address_country_code US address_zip 95131 address_state CA address_city San Jose address_street 123, any street business seller@paypalsandbox.com receiver_email seller@paypalsandbox.com receiver_id TESTSELLERID1 residence_country US item_name something item_number AK-1234 quantity 1 shipping 3.04 tax 2.02 mc_currency USD mc_fee 0.44 mc_gross 12.34 mc_gross_1 9.34 txn_type web_accept txn_id 51991334 notify_version 2.1 custom xyz123 charset windows-1252 verify_sign Ah5rOpfPGo5g6FNg95DMPybP51J5AUEdXS1hqyRAP6WYYwaixKNDgQRR
