# Configuration {#configuration}

TCA_API is configured through two mechanisms:

1.  **Site settings** — global per-site options such as the API prefix, pagination
    defaults, CORS headers, and OpenAPI access.
1.  **Resource definitions** — per-table PHP arrays that define which tables,
    columns, and operations to expose.
