When you add a AWS Lambda card to a Flow for the first time, you'll be prompted to configure the connection. This will enable you to connect your AWS Lambda account, save your account information, and reuse the connection for future AWS Lambda flows.
The account used to create the connection must have a policy that includes the Invoke and ListFunctions permissions. See Actions.
You can create multiple connections and manage them from your Connections page.
AWS Lambda recommends that you store your Access Key and Access Secret Key securely with your password. For information on viewing or resetting access keys, refer to AWS Lambda documentation.
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 AWS Lambda connections to share with your team.
Enter your Access Key.
Enter your Access Secret.
Select a Region.
