# Revise a catalogue Look

POST https://api.morphiaone.ai/v1/catalogue/looks/{look_id}/revisions
Content-Type: application/json

Writes the next revision of the look as a `draft`: its whole list of
applications, never a patch, compiled like a create. An earlier revision and what
it pinned never change. A retired look takes no revision (`409 LOOK_RETIRED`).
Send an `Idempotency-Key`: a retry with the same key and the same request
answers the first response, byte for byte, with `Idempotency-Replayed: true`,
so a response you did not receive is safe to retry.
Requires the `catalogue.write` scope, which your account operator provisions; no other
catalogue scope implies it. Served only where the catalogue is enabled for your
environment.
