How can I determine which Pull Request a commit belongs to using the GitHub API?

Given a commit SHA, I'd like to use the GitHub API to determine which pull request it belongs to.

GitHub displays this information on the commit page:

PR link for a commit

This information isn't in the API response for that commit, however:

curl --silent 'https://api.github.com/repos/hammerlab/pileup.js/commits/ee49f07dba3821109b3cf45404446f434a897558' | grep 328
(nothing)

Is it possible to get this information using the GitHub API? I realize that I could crawl all the recent PRs for the repo, but this seems inefficient.

For context: I'd like to do this from a Travis-CI "push" job, where I have access to the SHA but not any information about whether it's part of a pull request.

Solution

  • It is possible, using the Search API, which supports this feature:

    https://help.github.com/articles/searching-issues/#search-by-the-commit-shas-within-a-pull-request

    For example:

    https://api.github.com/search/issues?q=ee49f07dba3821109b3cf45404446f434a897558

    returns a single result, which is this pull request:

    https://api.github.com/repos/hammerlab/pileup.js/issues/328
