Hi @Charles S Thanks for your question!
It sounds like you’re trying to add a contact to a group in Google Contacts, is that right? If so, then you’ll need the ID of the contact to use in the Add Contact to Group action. To get the ID, you’ll need to add a search step in the Zap.
So overall the Zap would look like this:
Trigger: Streak (whichever trigger you’re using)
Action: Google Contacts - Find Contact
Action: Google Contacts - Add Contact to group
Will all of the contact’s in Streak already be a Contact in Google Contacts? If some of them might not already be in Google Contacts, then you can set up the Find Contact step to handle that. In the Find Contact step, tick the box that says ‘Create Google Contacts Contact if it doesn’t exist yet?’ and then add any details that you need to create the contact.

In the Add Contact to Group step, for the ‘Contact’ option, select ‘Custom’ and then add the ID of the contact from the Find Contact step.
That should get you all set, let me know if you have any questions!
