How to roll back a Google Ads script to an earlier version

Edit a script directly in Google Ads and the previous code is gone. If the change breaks something, you are left to remember what it used to say.

Versions in chiliad

Every save creates a version. Each one records:

• the full code at that point,
• who saved it,
• where the change came from: the dashboard, Claude, a restore, or a marketplace update.

Open a script and go to the Versions tab to see the list.

Comparing

Click Compare on any version to see it side by side with the current code, with the differences highlighted. This is usually the fastest way to find what changed between "worked on Monday" and "fails today".

Restoring

Click Restore on the version you want back. It becomes the current code, and every account that runs the script uses it on the next run. Nothing has to be done in Google Ads.

A sensible routine

1. Before a risky change, note the time of the current version.
2. Save the change and watch the next run in the History tab.
3. If it fails, restore the earlier version first, then investigate at leisure.

Settings have a history too

Per-account values are tracked separately. The Config changes list on the same tab shows which value was changed for which account, by whom and when — useful when a script suddenly behaves differently for one client only.
