An object that defines the filters to use to retrieve only the items you require. Each field you add will be an additional filter to apply to the request. The filter key needs to be an attribute name (e.g. label), followed by an underscore and an operator name (e.g. eq for "equals"). For example, if you want to see all tokens with label my_label, the proper syntax will be ?filter[label_eq]=my_label. For detailed information, please see the Filtering section in our Guides.
