is it possible to squash commits via Github API?

Question

I've successfully implemented automatic file creation/update via Github V3 Rest API, however the only downside is that for each file I have a commit.

There is a possibility to do the same for multiple files, but unfortunately it involves some concepts I still haven't mastered and it will take me some time until I get there since I have more urgents stuff on my TODO list.

In the meanwhile, I can totally live with that or simply squash the last N commits, which I imagined should be relatively easy, since locally it's just a matter of

git reset --soft HEAD~N
git commit -m ".."

but I couldn't find anything on the docs or online

So my question is: how can I squash the last N commits, non interactively, using Github API?

Ps: I don't care if it's v3 or v4 as long as I get it done

Because this way I don't have to have the project cloned locally — elect, May 10 '21 at 22:30
If you don't want an answer that says "use Git", don't use the [tag:git] tag. — torek, May 10 '21 at 23:25

I did not see a squash feature directly through API.

You would need to:

create a branch at HEAD-N commits, through the create ref API
reset your current branch to HEAD-N sha, with force boolean parameter set to true?
create a pull request from your new branch to your old reset branch
merge the PR, with the merge_method parameter set to squash

Pretty convoluted, but it should work (entirely through script, without having to clone the repository).
