}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
Discounts in one state. An unrecognised value is a 400 naming the accepted set, not an empty page: a campaign tool asking which codes are live would otherwise send a near-miss like "enabled" or "Active", receive an empty list, and conclude the merchant is running no promotions.
Discounts touched at or after this RFC3339 instant, for reconciling incrementally instead of re-reading the whole list. Supplying it CHANGES THE ORDER of this endpoint: the default walk descends created_at, and this one climbs updated_at, because that is the only ordering in which a keyset walk over a column the merchant keeps rewriting cannot skip a row. THIS IS THE LIST WHERE MISSING AN EDIT COSTS MOST: a discount's status, window and budget decide what a shopper is charged, so a client that misses a deactivation keeps offering a promotion the merchant has already withdrawn. A discount edited mid-walk moves forward past your position and is returned again, so the walk is AT LEAST ONCE: apply the state of each row you receive and a repeat costs nothing. The bound is INCLUSIVE, so resuming from the newest updated_at you hold re-delivers the rows sharing that instant rather than dropping the ones your last page did not reach. A cursor belongs to ONE ordering and is refused by the other. ARCHIVED DISCOUNTS LEAVE THIS WALK SILENTLY, as they leave the default list: it reports what changed, not what went away.
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.
