trying to locate where I find Gizmo contact ID
Can you please explain what you mean by the terms “Gizmo contact ID” and “Gizmo invite link”?
If you can provide some more details about what you are trying to accomplish the Community members can do a better job of helping you.
If you are using a SurveyGizmo Email Campaign, you can download all contact ID’s and unique invite links via the ‘export contacts with send status’ link found on the Contacts tab.
Might this be what you are looking for?
Hope this helps!
