Prerequisites

Before you connect, you must first do the following:

• Connect a data source to your CData Connect Cloud account. See Sources for more information.
• Create a Workspace. Later, you will use the OData Service URL on that page (https://cloud.cdata.com/api/odata/{workspace_name}) with the relevant workspace name to establish the connection.
• Generate a Personal Access Token (PAT) on the Settings page. Copy this down, as it acts as your password during authentication.
