Path Parameters
Response
Tax code
A tax classification code for products (e.g. AvaTax P0000000 generic tangible, ND040000 non-taxable digital, etc.). When AvaTax is the active jurisdiction provider, avatax_tax_code mirrors the canonical AvaTax tax code so jurisdiction sourcing flows through. Soft-delete refuses with HTTP 409 if any product still references the code (FK guard against orphaned product tax classification). Scope: tax_codes:read / tax_codes:write / tax_codes:delete.
"tax_code"
Operator-defined code unique per entity. 1..50 chars.
Human-readable label. 1..150 chars.
If false, products with this code are exempt from sales tax.
Optional grouping label (e.g. 'general', 'food', 'digital').
Mirrors the AvaTax tax code when AvaTax is the active provider.
Free-form caller metadata. Default {}.
