Invoke an AWS Lambda Function

Invoke a Lambda function synchronously and return its result.

Setup and use

Choose a Lambda function name or ARN and its AWS region. In Open Flow, set both in Sign the Lambda request, bind access key ID and secret access key to secret Variables, and grant lambda:InvokeFunction. With temporary credentials, bind the same session token secret Variable to Session Token in the signing node and X-Amz-Security-Token in Invoke Lambda. Leave both unset for long-lived credentials. In n8n, configure the function and AWS credential in AWS Lambda. Run manually.

Behavior

The workflow invokes $LATEST synchronously with an empty payload and returns the response. The example region is ap-south-1; use the function’s actual region. Invocation and function errors stop the run. An uncertain invocation may already have executed; check the function’s effects before retrying. Lambda responses are held in execution history.

Changes to the source

Replace the original account-specific function ARN with configuration. Open Flow signs the Lambda API request; n8n retains the native AWS Lambda node.
