Accessing Merge Settings via the GitLab API

Question

I would like to view and perhaps change the merge settings in GitLab (see the screenshot). How do I do this via the API?

Answer 1

If this is when creating a project there is a string named "merge_method" & "remove_source_branch_after_merge"

 merge_method
 remove_source_branch_after_merge

So this would be

GET /projects id/merge_method 

for existing projects you can use

https://docs.gitlab.com/ce/api/projects.html#project-merge-method
