Using the BitPay PHP Lite library

This library provides a convenient abstraction of BitPay's cryptographically-secure API and allows payment gateway developers to focus on payment flow/e-commerce integration rather than on the specific details of client-server interaction using the API. This library optionally provides the flexibility for developers to have control over important details, including the handling of private tokens needed for client-server communication.

Dependencies

You must have a BitPay merchant account to use this library. It's free to sign-up for a BitPay merchant account.

If you need a test account, please visit https://test.bitpay.com/dashboard/signup and register for a BitPay merchant test account. Please fill in all questions, so you get a fully working test account. If you are looking for a testnet bitcoin wallet to test with, please visit https://bitpay.com/wallet and create a new wallet. If you need testnet bitcoin please visit a testnet faucet, e.g. https://testnet.coinfaucet.eu/en/ or http://tpfaucet.appspot.com/

For more information about testing, please see https://bitpay.com/docs/testing

Usage

This library was built and tested using the PhpStorm IDE; the source code tree is directly compatible with Other PHP IDEs. Library dependencies can be downloaded by executing the following command at the root of the library:

php composer.phar install

Getting your client token

First of all, you need to generate a new POS token on your BitPay's account which will be required to securely connect to the BitPay's API.
For testing purposes use:
https://test.bitpay.com/dashboard/merchant/api-tokens

For production use:
https://bitpay.com/dashboard/merchant/api-tokens

Click on 'Add New Token', give a name on the Token Label input, leave the 'Require Authentication' checkbox unchecked and click on 'Add Token'. The new token will appear and ready to use.

Installation

Composer

Install Composer

curl -sS https://getcomposer.org/installer | php

Install via composer by hand

Add to your composer.json file by hand.

{
    ...
    "require": {
        ...
        "bitpay/sdk-light": "~1.0"
    }
    ...
}

Once you have added this, just run:

php composer.phar update bitpay/sdk-light

Install using composer

php composer.phar require bitpay/sdk:~3.0

Initializing your BitPay light client

Once you have the environment file (JSON or YML previously generated) you can initialize the client on two different ways:

// Provide the full path to the env file which you have previously stored securely.

$bitpay = BitPaySDKLight\Client::create()->withFile([FULL_PATH_TO_THE_CONFIG_FILE]);

$bitpay = new BitPaySDKLight\Client("CFJCZH3VitcEER9Uybx8LMvkPsSWzpSWvN4vhNEJp47b", BitPaySDKLight\Env::Test);

Create an invoice

$invoice = $bitpay->createInvoice(new Invoice(50.0, "USD"));

$invoiceUrl = $invoice->getURL();

$status = $invoice->getStatus();

WARNING: If you get the following error when initiating the client for first time: "500 Internal Server Error` response: {"error":"Account not setup completely yet."}" Please, go back to your BitPay account and complete the required steps. More info here

Retrieve an invoice

$invoice = $bitpay->getInvoice($invoice->getId());

Get exchange Rates

You can retrieve BitPay's BBB exchange rates.

$rates = $bitpay->getRates();

$rate = $rates->getRate(Currency::USD); //Always use the included Currency model to avoid typos

$rates->update();
