Unable to find available versions of an endpoint

I might just be completely blind but I’m not able to find the available versions of the filing history endpoint (or any other endpoint for that matter). Does anyone know how to retrieve the available versions for an endpoint?

Sorry for not providing links to the mentioned resources, the post isn’t allowing me to…

The API Versioning guide states that each resource (which I’m interpreting as resource=endpoint) is versioned independently, yet I see no mention of which versions are available for the list filing history endpoint, nor do I see it in the API response. I’ve attempted adding a Accept: version=1 (and other variants) to the request header and then get a 406 response, matching the expected behaviour in the above linked guide. This indicates that the endpoint is indeed versioned, I’m just passing an incorrect version. When doing the same to the Get Document Metadata endpoint I can add whichever version I want in the accept header and still get a 200 OK, indicating this endpoint is not versioned.

You are not blind, I believe the versioning is still mentioned in places but I’m not aware (at least in the Public Data API) it is in practice functional. As you say - some of the machinery appears to be in place.

I haven’t seen any official Companies House information either way on this (you can try searching this forum) however.

See e.g. thread touching on this from 2018:

It would be good to have official notice from Companies House on this though!
