Configuration

Connection parameters can be defined in the application configuration:

<?php

return array(
    'sake_bwa' => array(
        'connection' => array(
            'default' => array(
                'options' => array(
                    // see \Sake\BlockchainWalletApi\Service\BlockchainWalletOptions for all configurations
                    'url' => 'https://blockchain.info/de/merchant/', // note on your country
                    'guid' => 'your My Wallet identifier (found on the login page)',
                    'main_password' => 'Your Main My wallet password',
                    'second_password' => 'Your second My Wallet password if double encryption is enabled',
                ),
                'client' => 'Service factory name for Http Client, Lazy-loads a Zend\Http\Client instance if none registered'
            )
        )
    )
);

Registered service names

sake_bwa.service.default: a \Sake\BlockchainWalletApi\Service\BlockchainWallet instance to send requests to the api
sake_bwa.service.response: a \Sake\BlockchainWalletApi\Service\ResponsePluginManager Service plugin manager to create responses via api method name
sake_bwa.service.request: a \Sake\BlockchainWalletApi\Service\RequestPluginManager Service plugin manager to create requests via api method name
sake_bwa.service.input_filter: a \Sake\BlockchainWalletApi\Service\InputFilterPluginManager Service plugin manager to create input filter via api method name
sake_bwa.service.hydrator: a \Zend\Stdlib\Hydrator\ClassMethods instance with strategies and filters for requests/responses

Registered view helper

To use this view helper you must add zendframework/zend-view to your composer dependencies.

satoshi: a \Zend\View\Helper\AbstractHelper instance which converts satoshi to other unit e.g. bitcoin

Examples

This module is very easy to use. However, these code snippets should help you to start.

Send bitcoins

Here is an example how to send a transaction to a bitcoin address:

<?php
use Sake\BlockchainWalletApi;

// $sl is the service locator
$blockchain = $sl->get('sake_bwa.service.default');

/* @var $request BlockchainWalletApi\Request\Send */
$request = $sl->get('sake_bwa.service.request')->get('payment');
// or
$request = new BlockchainWalletApi\Request\Send();

$request->setAmount(100000); // in satoshi
$request->setTo('1KwbP2sRHW7uDsxnW8sBbymVwnSsm8cFXC');

try {
    // validate request
    if ($blockchain->isValid($request)) {
        /* @var $response BlockchainWalletApi\Response\Send */
        $response = $service->send($request);
        // access to response data
        $transactionHash = $response->getTxHash();
    }
} catch (BlockchainWalletApi\Exception\ExceptionInterface $exception) {
    // error handling
}

Send bitcoins to multiple addresses

Here is an example how to send a transaction to multiple recipients in the same transaction.

<?php
use Sake\BlockchainWalletApi;

// $sl is the service locator
$blockchain = $sl->get('sake_bwa.service.default');

/* @var $request BlockchainWalletApi\Request\SendMany */
$request = $sl->get('sake_bwa.service.request')->get('sendmany');
// or
$request = new BlockchainWalletApi\Request\SendMany();

$request->setRecipients(
    array(
        new BlockchainWalletApi\Request\Recipient('1BzHqGWhdpXyLqiYkAT7sasfCoffYo79tT', 10000),
        new BlockchainWalletApi\Request\Recipient('1NqH4QkkjDErD9TNC7arDQVMv4zKgfCzmb', 10000),
    )
);

try {
    // validate request
    if ($blockchain->isValid($request)) {
        /* @var $response BlockchainWalletApi\Response\SendMany */
        $response = $service->send($request);
        // access to response data
        $transactionHash = $response->getTxHash();
    }
} catch (BlockchainWalletApi\Exception\ExceptionInterface $exception) {
    // error handling
}

Get wallet balance

Here is an example how to retrieve wallet balance:

<?php
use Sake\BlockchainWalletApi;

// $sl is the service locator
/* @var $blockchain BlockchainWalletApi\Service\BlockchainWallet */
$blockchain = $sl->get('sake_bwa.service.default');

/* @var $request BlockchainWalletApi\Request\WalletBalance */
$request = $sl->get('sake_bwa.service.request')->get('balance');
// or
$request = new BlockchainWalletApi\Request\WalletBalance();

try {
    // validate request
    if ($blockchain->isValid($request)) {
        /* @var $response BlockchainWalletApi\Response\WalletBalance */
        $response = $blockchain->send($request);
        // access to response data
        $balance = $response->getBalance(); // in satoshi
    }
} catch (BlockchainWalletApi\Exception\ExceptionInterface $exception) {
    // error handling
}

Using view helper to convert satoshi to other unit e.g. bitcoins

Here is an example how to use satoshi view helper to convert satoshi to an other unit:

<?php
// assume we are in a template

/* @var $response \Sake\BlockchainWalletApi\Response\WalletBalance */
echo $this->satoshi($response->getBalanace(), 'BTC'); // Bitcoin
// or
echo $this->satoshi($response->getBalanace(), 'mBTC'); // Milli Bits
// or
echo $this->satoshi($response->getBalanace(), 'uBTC'); // Micro Bitcoin
