KEDA CloudEventSource API

The CloudEventSource and ClusterCloudEventSource custom resources define HTTP or Azure Event Grid destinations where KEDA delivers CloudEvents when scaling events occur. Events follow the CloudEvents specification v1.0 and carry reason codes and messages for events such as ScalerError, ScaledObjectReady, ScaledObjectDeleted, and AuthenticationFailed. Optional event type filters allow consumers to subscribe to only the events they care about.

Where this information came from

This is an independent, third-party profile of KEDA CloudEventSource API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
