In QuantConnect Cloud and when you use the Lean CLI to deploy to the cloud, you authenticate through the deployment wizard, so you don't need to create API credentials. To use Webull locally with the Lean CLI—to download data, backtest, research, or trade live—you need an App Key, App Secret, and the account ID of the Webull account you want to trade. The following steps summarize how to create these credentials. For the full process with screenshots, see Individual Application API in the Webull developer documentation.
