apply layout
Authorizations
An API key (es_live_…) from Settings, under API keys, or an OAuth access token.
Headers
Retry a paid dispatch safely: the same key returns the job already dispatched instead of charging again.
The workspace this one call acts in, when it is not the key's own.
Body
The timeline id.
split-h, split-v, pip-bottom-right, pip-bottom-left, pip-top-right, pip-top-left, main-sidebar, row3, stack3, grid-2x2, grid-3x3, grid-4x4 1fill, fit Placing items only: the span of the timeline the layout occupies, in seconds. Required with item, ignored with clip_id.
The revision get_timeline returned. A stale one fails with revision_conflict instead of applying; so does no revision once a user edited the timeline in the app since this connection last read it.
Optional: one sentence shown to the user beside this action.
