Powerful, flexible, lightweight interface to the BitPay Bitcoin Payment Gateway API.

Installing via Composer

The recommended way to install the BitPay PHP Client is through Composer.

# Install Composer
$ curl -sS https://getcomposer.org/installer | php

# Add BitPay as a dependency
$ php composer.phar require bitpay/php-client

After installing, you need to require Composer's autoloader:

require 'vendor/autoload.php';

The library requires PHP 5.3+ and is PSR-0 compatible.

Basic Usage

To create an invoice:

<?php

require 'vendor/autoload.php';

$bitPay = new BitPay\BitPay(
  new BitPay\Request\Curl,
  new BitPay\Encrypter\Hash('API-KEY'),
  'API-KEY',
  $options // array, optional
);

$invoice = $bitPay->createInvoice($orderID, $price); // returns Invoice Object

With invoice creation, orderID and currency are the only required fields. If you are sending a customer from your website to make a purchase, setting redirectURL on BitPay constructor options is required.

Response will be an object with information on your newly created invoice. Send your customer to the url to complete payment:

class stdClass#5 (10) {
  public $id =>
  string(10) "EXAMPLE-ID"
  public $url =>
  string(40) "https://bitpay.com/invoice?id=EXAMPLE-ID"
  public $posData =>
  string(67) "{"posData":[],"hash":"HASH"}"
  public $status =>
  string(3) "new"
  public $btcPrice =>
  string(6) "1.0000"
  public $price =>
  int(1)
  public $currency =>
  string(3) "BTC"
  public $invoiceTime =>
  int(1386958726781)
  public $expirationTime =>
  int(1386959626781)
  public $currentTime =>
  int(1386958726861)
}

There are many options available when creating invoices, which are listed in the BitPay API documentation.

To get updated information on this invoice, make a get call with the ID returned:

<?php

require 'vendor/autoload.php';

$bitPay = new BitPay\BitPay(
  new BitPay\Request\Curl,
  new BitPay\Encrypter\Hash('API-KEY'),
  'API-KEY',
  $options // array, optional
);

$invoice = $bitPay->createInvoice($orderID); // returns Invoice Object

Options

When you instantiate BitPay you can pass options as a fourth argument. You can also set this options dinamically with setOptions(). Please look carefully through these options and adjust according to your installation.

Option	Default	Description
verifyPost	`true`	Whether to verify POS data by hashing above api key. If set to false, you should have some way of verifying that callback data comes from bitpay.com.
notificationEmail	`''`	Email where invoice update notifications should be sent.
notificationURL	`''`	URL where bit-pay server should send update notifications. See API doc for more details.
redirectURL	`''`	URL where the customer should be directed to after paying for the order.
currency	`'BTC'`	This is the currency used for the price setting. A list of other pricing currencies supported is found at bitpay.com
physical	`true`	Indicates whether anything is to be shipped with the order (if false, the buyer will be informed that nothing is to be shipped)
fullNotifications	`true`	If set to false, then notificaitions are only sent when an invoice is confirmed (according the the transactionSpeed setting). If set to true, then a notification will be sent on every status change.
transactionSpeed	`'low'`	Transaction speed: low/medium/high. See API docs for more details.
