Saucelab integration

[sarathsp23]

I am not able to execute tests on saucelab
I added this under executionDetails in the json, do I need to do anything else as I can't find much documentation on this. Also is sauce lab the only cloud option or is there any other cloud services I could integrate my tests?
"executionDetails": {
"appium_js_path": "/usr/local/bin/appium",
"appium_node_path": "/usr/local/bin/node",
"sauce":{
"sauceUserName":"xxxxxxxx",
"sauceAccessKey":"xxxxxxxxx"
}
}
