Hi Matt, Thanks for reaching out to the Google Ads API Forum.
With regards to your question "So, for example, Account A has an ad 1234, is it possible that an ad in Account B is assigned 1234?", as per this guide, Ad ID is not globally unique but (AdGroupId, AdId) pair is globally unique. I hope this clarifies. Please note that every object in Google Ads is identified by its own ID. Some of these IDs are globally unique across all Google Ads accounts, while others are unique only within a confined scope. Please see Basic Concepts for more information. Have a great day.
