WooCommerce REST API

Under WooCommerce → Price History, two optional checkboxes control whether price history data is attached to WooCommerce REST API product and variation responses (/wp-json/wc/v2/products, /wp-json/wc/v3/products, and the matching variation endpoints). Both are disabled by default.

• Expose lowest prior price in the WooCommerce REST API — When enabled, each response includes a wc_price_history object with a lowest property: a floating-point value that matches the tax-inclusive lowest price logic used on the storefront.
• Expose full price history in the WooCommerce REST API — When enabled, wc_price_history also includes history: an object whose keys are Unix timestamps (as strings in JSON) and whose values are prices (floats). Anyone who can read products through the REST API will see this data; enable only if your integrations need it. If nothing is stored yet, history is empty; reading products via the REST API does not create or backfill history rows.

This applies to the classic WooCommerce REST API, not the separate Store API used by some blocks (/wc/store/...).

For variable products, the parent product and each variation have their own history and product ID; the REST payload reflects the same product or variation as the endpoint, the same way debug export works per ID.
