filter | object or string | No | - | Optional raw Meta product filter as an object, sent to Meta as-is. Uses the same syntax as product set filters, so this is also useful to preview which products a product set filter would match. Operators like is_any, contains, i_contains, eq, neq, and and/or groups over catalog fields such as retailer_id, brand, category, availability, condition, or custom_label_0 to custom_label_4. Example: {“and”: [{“brand”: {“i_contains”: “nike”}}, {“availability”: {“eq”: “in stock”}}]}. Leave empty to list all products. |
