I understand that our Google Contact Update action currently only allows you to update using email addresses.
Engineering is already aware of this and are working on a fix.
As there is a backlog of tasks for them to fix, I won't be able to advise you on the exact ETA for this fix.
In the meantime, i would suggest that you proceed with your recipe creating using out HTTP connector which will allow you to customise the way you would like to interact with the Google Contacts API.
For more information, please check out the documentation at https://support.workato.com/support/solutions/articles/1000232000-http-using-the-http-adapter.
Hope this helps!
