Run Lambda Function With Data

The Run Lambda Function With Data step is used to execute a Lambda Function while providing it with specific payload data in JSON format. This enables you to pass information or parameters to the Lambda Function, which can be used by the Function during its execution.

Prerequisites 

• This step requires the Amazon AWS Module to be installed before it will be available in the toolbox, and an active AWS account. The Amazon WebServices Settings must also be configured.
• A dependency must be created after installing the module in order for the the steps to be properly used.

Common Errors

Could Not Parse Payload into JSON

If the Payload Data JSON input is invalid, the step will cause an error.

To correct this, change the input to be valid and properly arranged JSON.
