List trade credit ledger
The movements behind outstanding_minor: the append-only record of every charge against a buyer’s credit and every settlement of it. THE SIGN IS THE MEANING. A positive amount_minor draws credit down, a negative one frees it, and the plain sum of the column IS the outstanding balance. Taking an absolute value turns a reconciliation into gross turnover reported as debt. reference_type and reference_id are the pair a movement is idempotent on, and they are OPAQUE STRINGS WITH NO DECLARED ENUM. Match on them, do not switch on them: the checkout flow that will be the main producer does not exist yet, so there is no vocabulary to freeze and none is being invented. ?customer_id narrows it to one buyer. Omit it to walk the whole store in one ordered pass, which is what an accounts-receivable reconciliation wants. APPEND ONLY AT THE DATABASE GRANT, not by convention: no code path in this platform can update or delete a movement, which is what makes this a tamper-evident trail rather than a cache of the balance.
Authorizations
A secret API key. Publishable keys cannot reach this API. A key may carry an expiry, and an expired key is refused exactly like an unknown one, with a 401 that names no reason; check the key's expires_at in the dashboard rather than inferring it from a response. When a merchant rolls a key's secret they choose a grace window of up to 3 days, and for its duration BOTH the new secret and the one it replaced authenticate, so an integration moves over on its own deploy schedule instead of at the instant the button is pressed. Move before the window closes: after it, the old secret is refused. Nothing else about this contract moves with a roll. The key keeps its id and its scopes, so the only thing an integration updates is the credential itself.
Query Parameters
Restrict the page to one buyer's movements. Omit it to walk the whole store's ledger newest first, which is what an accounts-receivable reconciliation wants and what the dashboard's own per-customer view cannot do.
Rows per page. Out of range is a 400 rather than a silent clamp, so a client asking for more than 100 learns it did not get it.
1 <= x <= 100The next_cursor from the previous page. Opaque: decode nothing from it and construct nothing by hand, since its encoding is not part of this contract. Omit it to read the first page.
