List seo
Which resources in this store carry an SEO override. AN EMPTY PAGE MEANS “this store has overridden nothing”, NOT “this store has no SEO”. Every product, collection, category and page still has its own title and description underneath, and a content page carries per-page meta on top of that which rides read_pages. This family publishes the OVERRIDE LAYER and nothing beneath it, so a client reading an empty page as “no SEO configured” will be wrong for most stores. A re-upsert MUTATES A ROW IN PLACE WITHOUT MOVING IT: created_at is never rewritten, so a full re-sync cannot shift your window mid-walk. The cost is the other half of the same fact: a walk keyed on created_at will not surface an override rewritten after the walk began, so reconcile on updated_at rather than assuming page order tracks recency.
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 kind of resource. Omit it to receive all four. A value outside the enum is a 400, not an empty page, because "no override is of that kind" and "there is no such kind" are different facts and a client told the former stops looking.
product, collection, category, page 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.
