List saved filters in a workspace, ordered by id ascending. after is the switch between two modes. For backwards compatibility, omitting it returns the complete registry in one payload with no Pagination-Next header. Sending it returns bounded pages. For that bounded walk, pass after=0 on the first request, then pass each Pagination-Next value on the next request until the header is absent, which marks the last page. after=0 is the opt-in itself rather than a row id (real ids start at 1), and it means "start at the beginning" in whichever direction sort_order asks for, so it also bootstraps a sort_order=desc walk. An after value that is neither 0 nor a Pagination-Next cursor is not a real position and pages nothing. Results can include every filter class saved in the workspace, not only the ones this API authors; inspect filter_class before using the id or public_id as a resource's stored_filter_id. Treat returned order filters as read-only here and edit them in the ClickFunnels Orders UI. Create and update operations on this public endpoint author contact filters only. See Applying existing order filters in the Refine Filters Skill for passing an order filter to the orders list.
