Wait for an approval from a human reviewer before continuing
This pattern allows you to integrate an human review or approval process into your workflows.
The task sends a message to a SNS topic which sends a notification to a human reviewer or approver by email for example. The workflow then waits until the approver completes their review. Depending on the review outcome a different Lambda function can be invoked.
Waiting for completion of the review is done using the .waitForTaskToken service integration. The payload of the SNS message contains a task token, which is automatically generated by AWS Step Functions.
The task will pause until it receives that task token back with a SendTaskSuccess or SendTaskFailure API call.
