Which is the best way to get the latest commit information from a git repository using GitHub API (Rest API v3).
Option 1: GET /repos/:owner/:repo/commits/mast
It depends on your definition of "last".
for a given branch (like master), GET /repos/:owner/:repo/commits/master is indeed the last (most recent) commit.
But you can also consider the last push event: that would represent the last and most recent commit done (on any branch), pushed by a user to this repo.
