Properties
Note the following properties:
-
Timeout: Enter how long to wait for Lambda to time out.
If your Lambda invocation gets throttled, the request is retried. It is also retried if a general service failure (500 error) happens.
When a synchronous invocation returns an error, Amazon Connect retries up to three times, for a maximum of 8 seconds. At that point, the contact is routed down the Error branch.
Configuration tips
-
To use an AWS Lambda function in a flow, first add the function to your instance. For more information, see Add a Lambda function to your Amazon Connect instance,
