| `field_type` | string or SelectableOption | No | `all` | Filter by field type: 'all', 'dimension', or 'metric'. Default is 'all'. |
| `filters` | array of FilterItem | No | - | Use this to search fields by name or ID. Each filter must have a field, operator, and value. Available fields to filter by are: - 'id': The field ID  \[\{"field":"id","operator":"REGEXP\_MATCH","value":".*(session\|user).*"}] - 'name': The field name \[\{"field":"name","operator":"CONTAINS","value":"session"}] Filters are combined using AND logic. If you want to use OR logic, use relevant operators like REGEXP\_MATCH or IN\_LIST. |

| `value` | string | Yes | - | The value to filter by, always as a string: text, a number, or a regex. For IN\_LIST and NOT\_IN\_LIST, pass the values as one comma-separated string such as 'a,b,c', not as an array.
