GClick ID - Uploading offline conversions is coming with [Value is too short] error code
I'm trying to upload our offline conversions to Adwords by uploading the GClick ID manually into the Adwords interphase. I extracted the GClick code from the url from our server logs and tried to upload it and got an error message [Value is to short]. An example of this GClick ID is gclid=CI_bvOG_pc4CFe0B0wodZuANDg
So then I took the whole url and uploaded that (there's a 100 character limited) and I am getting still getting the error message [Value is too short].
What is it that I am missing in the upload?
