Webhooker is a small library for hosting webhook callbacks to receive and dispatch callbacks from
external services such as Twitch or Slack. This is done by running a webserver using SparkJava
and serializing JSON with GSON, and then managing Clients to map the request URL to callback(s).
The Gradle/Maven import string can be found at the `maven-central badge above!

* This example assumes a reverse proxy is routing

// Perform these callbacks whenever this client receives payload in the order provided.
client.addCallbacks((payload) -> System.out.println(payload.getRequest().body()));
// Get the callback url for this client, this will be provided to a service to POST to.
