Matomo Annotations API

The Matomo Annotations API exposes 7 operations of the Matomo Reporting API (module `Annotations`). Dated notes attached to a site so report readers can see what happened on a given day. Every operation is dispatched through the single `/index.php?module=API&method=Annotations.` entrypoint on the customer's own Matomo instance, self-hosted or on Matomo Cloud. The OpenAPI 3.1.0 document is Matomo's own, generated by its first-party ApiReference plugin.

Where this information came from

This is an independent, third-party profile of Matomo Annotations 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.
