We have been testing the measurement protocol for a while now to pass Google Analytics information from our servers. We are passing our internal unique user id to tid/cid
parameters and not the ga's.
Right now it looks like that in our current setup we are not able to generate any Audience reports and I would like to verify my concern that this is due the fact we are passing our own unique userId to the cid
parameter.
Is it possible to generate Audience reports using the measurement protocol without ga's cid
?
