# Publish a catalogue Variant revision

POST https://api.morphiaone.ai/v1/catalogue/variants/{variant_id}/publish
Content-Type: application/json

Makes an approved `revision` the one new try-ons render. `expected_generation` is
the `generation` you read; any other answers `409 GENERATION_CONFLICT` and moves
nothing. Publishing an earlier approved revision is rollback. A revision that is
not approved answers `409 REVISION_NOT_APPROVED`; a retired variant
`409 VARIANT_RETIRED`. Publishing the active revision at the current generation
answers the variant unchanged.
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.publish` scope, which your account operator provisions; no other
catalogue scope implies it. Served only where the catalogue is enabled for your
environment.
