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

Path Parameters

string<uuid>

Body

application/json

note

string

Response

Period closed

An accounting period. Closed periods refuse new journal entry postings (Rule A3). Year-end closing entries that roll revenue and expense activity into retained earnings are posted via a separate explicit endpoint (POST /v1/accounting_periods/{id}/close-fiscal-year). The monthly-period close does NOT by itself post a retained-earnings rollover JE. Verified against live dev RDS accounting.accounting_periods.
