Overview
Saved filters let you persist complex contact queries (field conditions, operators, and values) and reuse them from the contact list.
Usage
Build a filter on Contacts, then save it with a name. Filters are stored per site and respect user permissions: you still need permission to view contacts the filter returns.
REST API
Saved filters live under the /filters REST base. Typical routes include collection list/create, single-item read/update/delete, plus GET/DELETE /filters/default to read or clear the user’s default filter applied when opening Contacts.
Listing and creating filters require auto_form_crm_view_contacts; mutating filters may require edit permissions depending on the operation (see FiltersController for exact callbacks).
