Webhooks allow you to send data to a web endpoint in JSON format, so you can perform actions on an AWS account and extend the functionality of Kion. Webhooks make it possible to integrate your existing services and tools with Kion to perform actions that are difficult or not available via IAM policies and CloudFormation templates.
Webhooks can be attached to cloud rules as either a pre-rule or a post-rule. Pre-rule webhooks run before CloudFormations. Post-rule webhooks run after CloudFormations. Webhooks do not retry if they fail so it's the responsibility of the webhook owner to ensure the service is highly available. For more information, see Webhook Behavior (requires log in).
