Determine which GCLIDs are invalid
We run a Click Performance Report each day so that we can map GCLIDs in our web logs back to specific keywords/criteria. It would be nice if we could know which of these clicks Google considers to be invalid so that we can remove them from our internal reporting. Is it possible through any part of the API or reporting services to get this information?
Re: Determine which GCLIDs are invalid
To be honest, I've never used this call in the API. I'm not even sure if they ever released it. However, if they did, it's unlikely the CIDs would be part of it.
Your best bet is to ask over on the AdWords API forum here - https://groups.google.com/forum/#!topic/adwords-api/1IDyI0IvETw
Sorry I can't be of more assistance.
