The Writer API is versioned. The API version name is based on the date when the API version was released. For example, the current version is 2023-21-01.

When backwards-incompatible changes are made to the API, a new, dated version is released. The current version is 2023-21-01. Read our API upgrades guide to see our API changelog and to learn more about backwards compatibility.

The changelog lists every available version. To set the API version on a specific request, send a Writer-Version header.
