When you add a Zendesk card to a Flow for the first time, you'll be prompted to configure the connection. This will enable you to connect your Zendesk account, save your account information, and reuse the connection in new Flows that include Zendesk.
You can create multiple connections and manage them from your Connections page.
Create a new connection from an Action card
Click New Connection.
Enter a Connection Nickname. This is useful if you plan to create multiple Zendesk connections to share with your team.
Enter a Subdomain for your Zendesk instance.
Click Create. The Zendesk Sign In dialog appears.
In the Sign In dialog, enter an email address and password, then click Sign In, to log in to your Zendesk account.
If prompted, click Allow.
