Processes multiple Polygons in a single KML file

Hello,

Is there a way to process multiple polygons in a single KML file?
I need to return them as a single image and the NDVI averages.

I am using the following endpoints:
https://services.sentinel-hub.com/api/v1/process
https://services.sentinel-hub.com/ogc/fis/

Thanks

No, this is not possible at the moment.
We are working on batch processing for Statistical API (new version of FIS), so the “average” part will be available in a couple of months. For images, though, you will have to do the loop.
