Here is a curl example of how to push a shared-policy to a device group in Panorama. The example in the XML API Reference Guide 7.0 documentation has an url encoding issue due to the space in "entry name" Another, not so clean approach, is put %20 in the space "entry%20name" if using the example from the documentation
Push configuration to firewalls in a Panorama DeviceGroup
curl -k -d key=$KEY --data-urlencode "cmd=<commit-all><shared-policy><device-group><entry name='DC100-DG'/></device-group></shared-policy></commit-all>" -d 'type=commit' -d 'action=all' https://192.168.55.5/api/
