Meta ads reference
Answers to questions Meta's documentation leaves open, taken from our own measurements on the Graph API and Ads Manager. Every page says how and when a fact was checked: API version, date, what kind of object, and whether it was a real change or a validation-only request.
- Can you edit, rename, or unarchive a Facebook ad campaign? What Meta lets you change on archived campaigns, ad sets and ads, why unarchiving is not possible, and which rename rules Meta's live API actually enforces.
- Meta Special Ad Categories: targeting restrictions, API rules, and how to update existing ad sets Which targeting options Meta locks under Housing, Employment and Financial Products and Services, how tune_for_category works, and how to fix ad sets.
- How to change the Facebook Page on an existing ad (and when Meta blocks it) What happens when you change the Facebook Page on an existing ad, how comments and Instagram identity behave, and which ad sets Meta refuses to swap.
