Sometimes I saw a sorrow about Power Apps authoring experience, like: "It was working fine until last week, then I edited it with the latest Studio and it looks broken!" or "I don't see an option in the Studio version list!"

As you may know, Power Apps studio can edit app with specific authoring version when you add url parameter &studio-version=v3.21093.33.xxxxxx.

Usually, the authoring version should be chosen from list in Setting dialog though, it does not display old versions (few weeks ago or month ago) or sometimes only showing current version.

Besides of that, we can get version info from App detail screen as following

Authoring (studio) version in App versions

However, this is part of the Authoring version string, and the entire version number is needed to actually specify the URL parameter.

In this post I will show you how to retrieve authoring versions which can work on make.powerapps.com.

HealthDetail API

I found there is undocumented (=unsupported) HealthDetail API which contains several authoring version history with entire version number.

https://instance-wus2.create.powerapps.com/api/451f562d-fbd0-4eaf-908e-2213e0248035/healthdetail

where wus2 corresponds to "Preview (United States)" environment. (As far as I confirmed, eus is for United States and eas is for East Asia region)

[2022/09/01 updated] The API endpoint has been updated. (Thanks, txh for comment)

https://authoring.wus-il109.gateway.prod.island.powerapps.com/api/451f562d-fbd0-4eaf-908e-2213e0248035/healthdetail

Once you call this api with GET method, response data includes supported client versions:
