Create Menu Metafield

API operation: Open the endpoint in Scalar

Use POST /business/{business_id}/menus/{menu_id}/metafields to create a menu metafield. The operation documented here is MenuMetafield.register.

The documented schema requires administrator or business-manager authentication. Before creating a metafield, verify that menu_id belongs to the route business; do not assume the route enforces this parent relationship.

The supported value_type values are integer, decimal, boolean, text, and json. See List menu metafields.
