API Action - How to enter an array value?

In the API Action step, how to specify the value(s) for urllist for the following JSON Encoded parameters? I entered it in the Input Data area.

{"key": "your api key", "plugin_version": "MY123", "lossy": 1, "resize": 1, "resize_width": 1024, "resize_height": 1024, "cmyk2rgb": 1, "keep_exif": 0, "convertto": "+webp", "refresh": 0, "urllist": ["url1", "url2"]}
