The Flex Geoportal API enables adding WMTS, WMS, WFS, KML, GPX and GeoRSS layers.
It is important to note that Geoportal layers are projected under a specific projection (IGNF:GEOPORTAL*, IGNF:MILLER, See RIG). As such, any other image based service (like WMS, WMTS, WMS-C and al) has to be :
The Geoportal API also allows to display Geoportal's layers in plate-carre (IGNF:RGF93G, compatible with EPSG:4326) and other layers must be under the same plate-carre projection.

This method is recommended if you want a static loading of the layer. More information here.
