Each project, model, and deployment has a unique identification number. The easiest way to find out what the ID of the project, model, or deployment is to look it up in the web address (URL).
Below there are two IDs: one for the project (after projects/) and one for the model (after models/). (Note the IDs have been blurred for these images.)

You can find the project ID and the model ID by selecting the model in the Leaderboard (click on the model).
The same applies to deployments: the string that goes after deployments/ (see the screenshot below) represents Deployment Id.

If you don't know which model is associated with a particular deployment, you can go to the Deployments tab, click on the deployment you need (if there are several), and find the model in the Overview tab below the Content section. You can click on the model name and you'll be forwarded to the model's overview.
