Description
The WMTSLayer class is used to add an OGC Web Map Tile Service layer to the map. The default behavior of a WMTSLayer is to execute a WMTS GetCapabilities request, which requires using a proxy page or pushing the url to esriConfig.defaults.io.corsEnabledServers. This sample demonstrates how to specify the resource info so no proxy page is required.
