As well as through the supported repository hosts, you can set up your own auto deployment trigger via a JSON POST request, which many other services have integrations for. Before you can setup a custom trigger with your server's webhook, you'll need to [retrieve it](Article: #147) from your DeployHQ project.

If you navigate to the URL in a browser, it will display the necessary JSON payload required to send a request to the url to trigger a deployment.

The payload to use is:

```json
{
  "payload":{   
    "new_ref": "aabbccddeeff",  
    "branch": "master",
    "email": "user@example.com",
    "clone_url": "git@yourhost:path"
  }
}
```

* `new_ref` is the revision you wish to deploy to. If you wish to use the latest revision for the configured branch to deploy from automatically, simply send a string of `latest`.
* `branch` is the branch the revision is on (not used in SVN).
* `email` is the email address to be notified on completion/failure (according to project's OR server/server group's settings).
* `clone_url` is the path to your repository (as entered in the Deploy UI).
