Authorizations

Authorization
string
header
required

API key issued per entity via Settings > Developers > API Keys. Each key carries scopes (e.g. orders:read, products:write). Bearer token format: Authorization: Bearer ark_live_ent_Test keys use ark_test_ent_. Both are issued per entity
via Settings > Developers > API Keys.

Headers

Idempotency-Key
string

Client-generated unique key for idempotent POST/PATCH/DELETE operations. Alias for the Idempotency parameter. Max 255 chars. On retry with the same key, the original response is returned without re-executing the operation. Keys expire after 24 hours.

Maximum string length: 255

Response

Updated currency

A currency that the entity transacts in. USD is seeded on entity creation with is_base=true. Wave B multi-currency foundation: exchange_rates link non-base currencies to the base. Soft-delete refuses with HTTP 409 if the row is the entity's base currency; promote a different currency first via POST /currencies/{id}/set-base. Scope: currencies:read / currencies:write / currencies:delete. Rule 23 SSOT: is_base is flipped only by canonical setBaseCurrency (atomically demotes the previous base in the same transaction).
