 ## Establish a connection
 
-To use the Viam fleet management API, you first need to instantiate a [`ViamClient`](https://python.viam.dev/autoapi/viam/app/viam_client/index.html#viam.app.viam_client.ViamClient) and then instantiate an [`AppClient`](https://python.viam.dev/autoapi/viam/app/app_client/index.html#viam.app.app_client.AppClient).

+To use the Viam fleet management API, you first need to instantiate a `ViamClient` and then instantiate an `AppClient`.
 
-You can create an [API key](/manage/manage/access/) on your settings page.
+You will also need an API key and API key ID to authenticate your session.
+To get an API key (and corresponding ID), you have two options:
+
+- [Create an API key using the Viam app](/operate/control/api-keys/#add-an-api-key)
+- [Create an API key using the Viam CLI](/dev/tools/cli/#create-an-organization-api-key)
+
+The following example instantiates a `ViamClient`, authenticating with an API key, and then instantiates an `AppClient`:
