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.

application/json
​
baseline_date
string<date>
required

​
baseline_balance
number
required

The REAL bank statement balance at the anchor date.

​
keep_open_gl_line_ids

​
keep_open_bank_txn_ids
string<uuid>[]

Bank transaction UUIDs to KEEP unexcluded (feed lines that must remain matchable).

​
