Matomo AbTesting API

The Matomo AbTesting API exposes 17 operations of the Matomo Reporting API (module `AbTesting`). A/B test experiment management and results reporting. Every operation is dispatched through the single `/index.php?module=API&method=AbTesting.` 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.
