List marketing templates
The store’s marketing message library, newest first. A template holds the merchant’s WORKING COPY, which is what the next publish will snapshot and is not necessarily what is live: current_version_id names the version the send path renders. TWO FILTERS, NOT TWO ROUTES. ?channel= narrows to email, sms or push and ?status= to draft, active or archived. A value outside either enum is a 400 rather than an unfiltered page, because a page that quietly ignored your filter reads as “the store has no sms templates” when it has ten. PAGED BY CREATION TIME, not by updated_at. Ordering on updated_at would move a template to the front of the list every time the merchant saved it, and a client walking the library would meet the same row twice.
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
Narrow to one surface. Omit it for all three. An unrecognised value is a 400 rather than an unfiltered page: a client filtering on "e-mail" and receiving every template in the store would read an sms body as email copy.
email, sms, push Filter by lifecycle state. Omit it to receive all three. ONLY an active template has a published version behind it, so ?status=active is how you ask what a campaign can send right now; draft has never been published and archived has been retired, and neither is sendable. An unrecognised value is a 400 for the same reason as channel.
draft, active, archived 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.
