How to merge branch till specific commit id via REST API

[d00m178]

for merging two branches via the REST API I follow this advice:

Can I merge two branches via API call without pull request

Hey @travisw, Merging a git branch via the REST API is indeed not possible. But there might be a solution out there for you, You said that you don’t use the Pullrequests so what if we do only use it via the REST API? So we could create a pullrequest with branch A and B via the REST API, and merge this pullrequest. You need to make sure no approvers are needed or builds (this is done in the settings). Merge the pullrequest hence merging Branch A into Branch B. And if you want to you possibly…

and do it in 2 steps - create pool request like this:

Create pull request using command line or Jenkins

and then merge this PR via REST API.
it works ok.
but it merges branch1 from the last commit.

now I need merge branch1 to branch2 only till specific commit id from branch1. in git I can do like:

git fetch --all
git merge <commit_id>
git push

and after this branch2 has been merged only with commits till commit_id from branch1. How can I do the same via REST API? Also, as far I understand - this is NOT cherry-pick because I need merge not only ONE commit but more.
