Check whether a tax is in use

Return whether your company uses the tax: documents, products, contacts and company defaults of your company only (usage by other companies is not counted).

Useful for safe-deletion checks before calling DELETE.

Authorization

Your API key as a bearer token: fact_live_… in production, fact_test_… in sandbox. See the authentication guide.

In: header

Formatuuid

Formatuuid

Pin the API version (YYYY-MM-DD, Stripe-style date versioning) for this request; omit to use the key's pinned version, or the latest if none. Unsupported version → 400 unsupported_api_version; malformed → 400 parameter_invalid_format. The effective version is echoed in the Factuarea-Version response header. See the Versioning guide.
