When you add a Box card to a Flow for the first time, you'll be prompted to configure the connection. This will enable you to connect your Box account, save your account information, and reuse the connection for future Box Flows.
Note: You can create multiple connections and manage them from your Connections page.
To create a new connection from an Action card:
Click New Connection.
Enter a Connection Nickname. This is useful if you plan to create multiple Box connections to share with your team.
Log in to your Box account to authorize the connection.
In Box, click Grant Access. This saves your connection and returns you to your Flow.
