How to set up a cross-account OFFLINE conversion tracking if auto-tagging can't be enabled on MCC?

[Leongrin]

I am trying to set up a cross-account OFFLINE conversion tracking system on my MCC account, but I can't find the auto-tagging feature on the MCC account.

We will be using AdWords' API to upload the offline conversions; using the MCC token.

In order for us to upload the offline conversions, we need the GCLID parameter. But if I can't enable the auto-tagging on the MCC account, how can I get the GCLID?

I could enable auto-tagging on each of our linked accounts, but I am not sure it would work in our cross-account conversion tracking structure using the API's token from the MCC account.

How can I set up a cross-account offline conversion tracking using our MCC API's token if we can't enable auto-tagging on the MCC account?

Hi, 

You can set up and query cross-account conversion trackers via the API, but you must opt in your accounts to cross-account conversion tracking from the manager account. See this help center article for more information. If you have questions about opting in, please post those on the Advertisers community forum as they are better equipped to address questions related to the AdWords UI. Once you have completed that. You can use the AdWords API to set up and manage the conversion trackers. Please check this guide for more details about that. 

Thanks,
