If you have a build / deployment process for your site, it’s often useful to have a way to execute code in your theme or plugins after you commit or deploy your code changes.
GitHub, Bitbucket, and Beanstalk are common tools that allow you to configure a webhook URL that gets called as soon as you make a check-in or deployment.
Common uses are
<ul>
<li>Purge the cache after you deploy new theme code (WP Super Cache or W3 Total Cache)</li>
<li>After you build your JavaScript/CSS, trigger a backup of the live site</li>
<li>Trigger any WordPress hook</li>
<li>Run any other plugin or theme code you wish!</li>
</ul>
