White PHP

White makes accepting payments in the Middle East ridiculously easy. Sign up for an account at

Getting Started

Using White with your PHP project is simple.

If you're using Composer (and really, who isn't these days amirite?), you can simply run:

php composer.phar require white/white

.. or add a line to your composer.json file:

    "require": {
        "white/white": "*"

Now, running php composer.phar install will pull the library directly to your local vendor folder.

Note: If you're running on a shared host, then you may need to set the allow_url_fopen flag for the php commands. For the install command, for example, this would look like php -d allow_url_fopen=On composer.phar install. The -d overrides the php.ini settings, where allow_url_fopen is usually set to Off.

Using White

You'll need an account with White if you don't already have one (grab one real quick at and come right back .. we'll wait).

Got an account? Great .. let's do this.

1. Initializing White

To get started, you'll need to initialize White with your secret API key. Here's how that looks (fear not .. we're using a test key, so no real money will be exchanging hands):

require_once('vendor/autoload.php'); # At the top of your PHP file

# Initialize White object

That's it! You probably want to do something with the White object though -- it gets really bored when it doesn't have anything to do.

Let's run a transaction, shall we.

2. Processing a transaction through White

Now, for the fun part. Here's all the code you need to process a transaction with White:

  "amount" => 10500, // AED 105.00
  "currency" => "aed",
  "card" => array(
    "number" => "4242424242424242",
    "exp_month" => 11,
    "exp_year" => 2016,
    "cvc" => "123"
  "description" => "Charge for"

This transaction should be successful since we used the 4242 4242 4242 4242 test credit card. For a complete list of test cards, and their expected output you can check out this link here.

How can you tell that it was successful? Well, if no exception is raised then you're in the clear.

3. Handling Errors

Any errors that may occur during a transaction is raised as an Exception. Here's an example of how you can handle errors with White:

try {
  // Use White's bindings...
} catch(White_Error_Banking $e) {
  // Since it's a decline, White_Error_Banking will be caught
  print('Status is:' . $e->getHttpStatus() . "\n");
  print('Code is:' . $e->getErrorCode() . "\n");
  print('Message is:' . $e->getMessage() . "\n");

} catch (White_Error_Request $e) {
  // Invalid parameters were supplied to White's API

} catch (White_Error_Authentication $e) {
  // There's a problem with that API key you provided

} catch (White_Error $e) {
  // Display a very generic error to the user, and maybe send
  // yourself an email

} catch (Exception $e) {
  // Something else happened, completely unrelated to White

Testing White

It's probably a good idea to run the unit tests to make sure that everything is fine and dandy. That's also simple.. just run this command from the root of your project folder:

php vendor/bin/phpunit tests --bootstrap vendor/autoload.php

Note: you'll need to pull the development dependencies as well, using composer update --dev in order to run the test suites.
