Wait for an approval from a human reviewer before continuing
This pattern allows you to integrate a human review or approval process into your workflows with one-click email approval.
A Lambda function URL-encodes the task token and sends an email via SNS with clickable approve and reject links pointing to an API Gateway endpoint. The reviewer clicks a link to approve or reject without needing the CLI.
An API Gateway REST API receives the callback, and a handler Lambda decodes the task token and calls SendTaskSuccess to resume the workflow.
The workflow uses the .waitForTaskToken service integration to pause until the reviewer responds.
