> HTTP 409, from 4 operations of the Admin API.

Its problem `type`: `https://developers.tassyir.io/errors/offer-version-conflict`; its `title`: Conflict.

## What to do

Read the offer again (currentVersion is its version now) and send expectedVersion with the change, or leave expectedVersion out.

## Answered by

HTTP 409, from:

* [`PATCH /offers/{id}`](/api-reference/admin/offers/update-an-offer)
* [`POST /offers/{id}/pause`](/api-reference/admin/offers/pause-an-offer)
* [`POST /offers/{id}/publish`](/api-reference/admin/offers/publish-an-offer)
