The `Job ID` is a unique identifier for each Sauce Labs job, found in the URL of a jobs page and used by remote Selenium sessions. With this session ID, you can download screenshots, stop a job remotely, get faster support, and set job metadata like build-id using the Sauce REST API. The `session_id` method has been added to the remote driver, making it easy to obtain the session ID programmatically. This allows for tasks such as providing links to jobs, setting metadata with SauceWhisk, stopping a job remotely, downloading videos, and more with just a few lines of code.
