The sharing key goes in your feeder ini
For example
[client]
network_mode=true
log_file=/var/log/rbfeeder.log
key=Removed
sn=EXTRPI******
If however you are looking to link your receiver to your RB account this is normally done automatically within a short time of you srating feeding data
If however the automated process doesnt work for some reason contact
[email protected] detailing your EXTRPI**** sharer number and your account email address and ask that they link the receiver to your account
