second.php

<?php

// 1. Autoload the SDK Package. This will include all the files and classes to your autoloader
//require __DIR__  . '/php-client/autoload.php'; // Direct Donwload
require __DIR__  . '/vendor/autoload.php'; // Using Composer

// 2. Provide your Token. Replace the given one with your token
// https://accounts.blockcypher.com/dashboard
$token = 'c0afcccdde5081d6429de37d16166ead';
$apiContext = new \BlockCypher\Rest\ApiContext(
	new \BlockCypher\Auth\SimpleTokenCredential($token)
);

// Step 2.1 : Between Step 2 and Step 3
$apiContext->setConfig(
  array(
    'mode' => 'sandbox',
    'log.LogEnabled' => true,
    'log.FileName' => 'BlockCypher.log',
    'log.LogLevel' => 'DEBUG'
  )
);

// 3. Lets try to create a new webhook using WebHook API mentioned here
// http://dev.blockcypher.com/#webhooks
$webHook = new \BlockCypher\Api\WebHook();
$webHook->setUrl("https://requestb.in/slmm49sl?uniqid=" . uniqid());
$webHook->setEvent('unconfirmed-tx');

// 4. Make a Create Call and Print the WebHook
try {
    $webHook->create($apiContext);
    echo $webHook;
}
catch (\BlockCypher\Exception\BlockCypherConnectionException $ex) {
    echo $ex;
}
