Customiser mountings
Validate a mounting image attach
Dry-runs the attach: the slot must exist on this mounting, the upload must exist for this store and this API key, and its purpose must be the slot's. Nothing is written, the upload is not consumed, and no idempotency key is spent.
Overview
Requires customisers:write.
The staged bytes are deliberately not read, so this cannot tell you
whether the file is a usable image — that verdict only exists once the
attach reads the object, and reading it here would let a preflight mark
a good upload rejected. Treat a valid verdict as "the upload is
attachable", not "the file is sound".
Authorisation
Bearer token required. Include it in theAuthorization header.
Required scope: customisers:write
Path parameters
The customiser id.
Example: 1
The mounting id.
Example: 8
Which image to write: image or button_image.
Example: image
