StopExecution

Stops an execution.

This API action is not supported by EXPRESS state machines.

For an execution with encryption enabled, Step Functions will encrypt the error and cause fields using the AWS KMS key for the execution role.

A caller can stop an execution without using any AWS KMS permissions in the execution role if the caller provides a null value for both error and cause fields because no data needs to be encrypted.
