Create WebHook Sample

This sample code demonstrate how you can create a webhook, as documented here at: http://dev.blockcypher.com/#webhooks API used: POST /v1/btc/main/hooks

require __DIR__ . '/../bootstrap.php';

Create a new instance of WebHook object

$webHook = new \BlockCypher\Api\WebHook();

Basic Information

{
    "event":"unconfirmed-tx",
    "url":"https://requestb.in/slmm49sl",
 }

Fill up the basic information that is required for the webhook The URL should be actually accessible over the internet. Having a localhost here would not work.

There is an open source tool http://requestb.in/ that allows you to receive any web requests to a url given there.

NOTE: Please note that the use of https is recommended for webhooks.

The transaction or block associated with the event you subscribed to will be POSTed to the provided URL. The POST request will also include a X-EventType and a X-EventId HTTP header specifying the type of and id of the webhook which triggered the request. X-Eventtype: unconfirmed-tx X-Eventid: f1cef7d6-cfd9-459c-8ebc-42226ae2b1a7

$webHook->setUrl("http://requestb.in/rwp6jirw?uniqid=" . uniqid());

Event Types

Event types correspond to what kind of notifications you want to receive on the given URL. Complete event list: http://dev.blockcypher.com/#events

$webHook->setEvent('unconfirmed-tx'); $webHook->setHash('2b17f5589528f97436b5d563635b4b27ca8980aa20c300abdc538f2a8bfa871b');
