# For this to work correctly you need to have a valid SFR DMC service account
# to whicthe API password can be generated. A "space" is also necessary
# (space = a logical separation between clients), which will give you a
# specific spaceId
#
# Expected credentials looks a little like this:
# serviceId: 84920958892    - Random numbers
# servicePassword: XxXXxXXx - Random characters
# spaceId: 984348           - Random numbers
