Recurly PHP Client

The Recurly PHP Client library is an open source library to interact with Recurly's subscription management from your PHP website. The library interacts with Recurly's REST API.

Requirements

cURL and OpenSSL

The PHP library depends on PHP 5.6 (or higher, though only PHP 7.2 or newer is officially supported) and libcurl compiled with OpenSSL support. Open up a phpinfo(); page and verify that under the curl section, there's a line that says something like:

libcurl/7.19.5 OpenSSL/1.0.1g zlib/1.2.3.3 libidn/1.15

Please ensure that your OpenSSL version supports TLS v1.2 (or higher) and that it meets PHP's requirements for the OpenSSL cryptography extension. Some older versions of OpenSSL will not necessarily work properly with the Recurly API. For security reasons, it is strongly encouraged to use the latest version of OpenSSL.

Timezone

You will need to specify your server's timezone before using the Recurly PHP client. This is necessary for the library to properly handle datetime conversions. You can do this in your php.ini file:

date.timezone = 'America/Los_Angeles'

or in your PHP script:

date_default_timezone_set('America/Los_Angeles');

Headers

In accordance with section 4.2 of RFC 2616, HTTP header fields are case-insensitive.

Installation

Composer

If you're using Composer, you can simply add a dependency on recurly/recurly-client to your project's composer.json file.

{
    "require": {
        "recurly/recurly-client": "2.12.*"
    }
}

Git

If you already have git, the easiest way to download the Recurly PHP Client is with the git command:

git clone git://github.com/recurly/recurly-client-php.git /path/to/include/recurly

By Hand

Alternatively, you may download the PHP files in the lib/ directory and place them within your PHP project.

Initialization

Load the Recurly library files and set your subdomain and API Key globally:

<?php
require_once('./lib/recurly.php');

/* https://<your-subdomain>.recurly.com */
Recurly_Client::$subdomain = 'your-subdomain';
/* your private API key */
Recurly_Client::$apiKey = '012345678901234567890123456789ab';

If you are getting certificate verification errors that look like this:

Fatal error: Uncaught exception 'Recurly_ConnectionError' with message 'Could not verify Recurly's SSL certificate.'

Then there is likely a problem with your php or libcurl package and it cannot find your system's root CA certificates. Ideally you would want to fix your installation but if you cannot you can override the path manually:

// Example on my OS X system, the path will be dependent on your system so ask your sysadmin
Recurly_Client::$CACertPath = '/usr/local/etc/openssl/cert.pem';
