adminAppearanceThemeImpact

What activating a theme on the given channels would leave behind. Reports only; nothing is written.

A channel is listed when it currently runs a different theme and already holds sections built for it. Those sections are not deleted by activation — they stop being drawn, and return if the channel is pointed back at that theme.

Arguments

Argument	Type	Description
code	String!	Theme code being considered.
channelIds	[Int!]!	Channels the theme would be applied to.

Fields

Field	Type	Description
code	String	The theme code that was asked about.
impact	Iterable	One entry per affected channel, each { channelId, channel, currentTheme, customizations }. Empty when nothing would be left behind.

Use cases

• Confirmation dialog before switching — query with the channels the merchant ticked; an empty impact means the switch is uneventful and the dialog can be skipped.

Best practices

• Query impact bare. It is a JSON value and takes no sub-selection.
• A channel already on this theme is never listed, so an empty array is the normal answer when re-activating a theme a channel already runs.

Requires appearance.themes.
