Evaluating the product? Read the public Developers page first — what the API covers and where it lives in WordPress admin.

Terminology

Merchant docs use appointable product (the product type label in WooCommerce admin). REST/API responses use product_id on products with type: appointment. Same bookable product — different labels by audience.

API Base URL

Appointment REST endpoints use the wc-appointments namespace:

https://your-site.com/wp-json/wc-appointments/v2/

V1 endpoints remain available under /wp-json/wc-appointments/v1/. The WooCommerce core wc/v3/orders endpoint is extended separately to include appointment data — see Orders Extension.

For detailed endpoint documentation, see the REST API Overview.
