| customParameters | A sequence of custom parameters appended to the URL of all requests related to a layer. |
| disablePopup | Indicates whether to allow a client to ignore popups defined by the service item. |
| effect | Effect provides various filter functions to achieve different visual effects similar to how image filters (photo apps) work. |
| featureEffect | Feature Effect emphasizes or deemphasizes features that satisfy a filter using graphical effects |
| id | A unique identifying string for the layer. |
| itemId | Optional string containing the item ID if it's registered on ArcGIS Online or your organization's portal. |
| layerDefinition | A layerDefinition object defining the attribute schema and drawing information for the layer. |
| layerType | String indicating the layer type. Valid value of this property CSV |
| locationInfo | A locationInfo object defining how location information will be retrieved from a CSV file. |
| opacity | The degree of transparency applied to the layer on the client side, where 0 is full transparency and 1 is no transparency. |
| popupInfo | A popupInfo object defining the content of popup windows when you click or query a feature. |
| refreshInterval | Refresh interval of the layer in minutes. Non-zero value indicates automatic layer refresh at the specified interval. Value of 0 indicates auto refresh is not enabled. |
| showLabels | Labels will display if this property is set to true and the layer also has a labelingInfo property associated with it. This property can get stored in the web scene config. |
| showLegend | Boolean value indicating whether to display the layer in the legend. Default value is true. |
| title | A user-friendly string title for the layer that can be used in a table of contents. |
