The public checkout UI calls this when a donor changes a selected designation from one-time to a recurring schedule. If the optional session id is absent or expired, the controller creates a new frontend session before writing the `saved_designation_frequency` hash. ## OpenAPI ````yaml get /frontend/checkout_update_designation_frequency_only/{client_id}/{hysform_id}/{designation_id}/{id}/{frequency}/{session_id} openapi: 3.0.0 info: title: Gratona API description: >- REST API for the Gratona fundraising platform, including donor, donation, sponsorship, program, event, and integration workflows.
