It can also optionally take a `timeout` and `endpoint_url` parameter however these are optional and will use standard defaults if not provided.
These can be supplied via the standard 'creds.json' like so:
{% highlight json %}
"softlayer": {
"username": "myusername",
"api_key": "mysecretapikey"
}
{% endhighlight %}
To maintain compatibility with existing softlayer CLI services these can also be provided by the `SL_USERNAME` and `SL_API_KEY` environment variables or specified in the ~/.softlayer.
More information about these methods can be found at [the softlayer-go library documentation](https://github.com/softlayer/softlayer-go#sessions).
## Usage
Use this provider like any other DNS Provider:
{% highlight js %}
var registrar = NewRegistrar("none","NONE"); // no registrar
var softlayer = NewDnsProvider("softlayer", "SOFTLAYER");
