Undo An Ad Change

Put back an Amazon Ads change that was made through Launch Fast.

This tool changes your Amazon Ads account

undo_ad_change changes your Amazon Ads account right away. Launch Fast records the undo like any other change. Launch Fast tells the assistant to confirm the undo with you first, unless you named the change exactly. Your AI app may also ask before it runs a change tool. An undo of a new campaign archives it, and Amazon cannot bring back an archived campaign.

What It Does

undo_ad_change puts back one change that was made through Launch Fast, by an AI app or by Launchie.

You undo a change only by asking your AI app. Ad Changes in the Launch Fast iOS app shows the history but cannot undo.

Change	What the undo does
Bids, budgets, and statuses	They go back to their old values. A keyword that used its ad group's default bid before the change goes back to the ad group's default bid as it is now.
Added keywords and negative keywords	They are removed.
A new campaign	It is archived for good. Amazon cannot bring back an archived campaign.

If a value changed again after the change, the undo refuses that value and leaves it as it is. The answer lists it.

When To Use It

Use it when a change did not work, or when you made it by mistake. Find the change id with get_ad_changes, or take it from the answer of the change.

Inputs

Input	Required	Values	Example
`change`	Yes	The change id. It starts with `ac-`.	`ac-5k2x7tq3mvfcd2s4nt6ye6wpra`
`reason`	No	One line on why, up to 300 characters. Launch Fast saves it with the change. The default is "Asked for in chat."	`The bid cut lost too many sales`

What The Answer Contains

A status: applied, partly applied, not applied, going through, or unconfirmed.
A table with one row for each value: what went back, and the result.
The items that the undo did not touch, because they changed again after the change.
The id of the undo. You cannot undo an undo.

Example Prompts
