What It Does

get_ad_changes lists the changes made to your Amazon Ads through Launch Fast. It shows changes by an AI app and by Launchie, the assistant in the Launch Fast app. For each change, it shows what changed and how it did.

Launch Fast measures the result as the profit change in the two weeks after the change, against the two weeks before it. Until the result is in, the detail of the change shows the day that it is due.

Campaign renames and Launchie settings changes are not in the list.

You can also see this history in Ad Changes in the Launch Fast iOS app. It is read-only there. To undo a change, ask your AI app. It uses undo_ad_change.

When To Use It

To see the changes made this month and their results.
To find the ac- id of a change before you undo it.
To check a change that was in progress when its answer came back.

Inputs

Input	Required	Values	Example
`change`	No	One change id, for its detail. Leave it out for the list.	`ac-5k2x7tq3mvfcd2s4nt6ye6wpra`
`days`	No	The period of the list: `7`, `30` (default), or `90` days	`90`
`cursor`	No	The next page of the list, from the answer. Leave it out with `change`.

What The Answer Contains

The list shows up to 25 changes on each page, with these columns:

Column	Meaning
`change`	The change id
`what`	What changed
`campaigns`	The campaigns it changed. For an undo, the campaigns it put back.
`applied_on`	The day it was applied, in UTC
`made_by`	The AI app or Launchie
`state`	`measured`, `measuring`, `reversed`, `not applied`, `no result`, or `undo`
`profit_change`	The profit change, when the change is measured

State	Meaning
`measured`	The result is in.
`measuring`	The result is not in yet.
`reversed`	An undo or a later change put this change back, or a later change on the same setting took it over. It has no result of its own.
`not applied`	Amazon did not apply the change.
`no result`	The ads data for those weeks never arrived.
`undo`	This change is an undo. It put back an earlier change.

A change in state undo is the undo itself. The change that it put back shows as reversed. When the page has an undo, the answer adds a note that says to count only the reversed changes as undone.

The list also adds up the profit change of the changes that are measured or still measuring. When no change in the period is measured or measuring, the summary says "None has a profit result yet." and the profit_change total is null, not $0.00.

The detail of one change shows each value that changed, its result, and the day that the result is due.
