Webhooks were created to allow web applications to become more extensible, customizable, and ultimately more useful. Webhooks let you develop "instant" push notifications. A push notification is simply a HTTP POST, that is triggered by some action. In this case, the action is checking into a particular branch of your source code repository over at Github. In order to set webhooks for your repository, you need to be the owner (administrator) of the repository. Please check and make sure you are the admin on your repository before sending us a support ticket.
Visit the repository you're trying to set up deploy hooks for in Github or your source code versioning tool.
From the left hand sidebar menu, select "Service Hooks".
From the Available Service hooks, choose "Webhook URLs"
Enter the correct Webhook URL from your DeployButton page.
You're all set to automatically deploy as soon as you've pushed to the correct branch of your repository that your DeployButton is set to.
