Is there a way to get the Github Pull Request number during a build of Google Cloud Build?

During a Google Cloud Build, is there a way to get information regarding the fact that the build is associated with a Pull Request like the Pull Request number/id for example?

It seems that no such substitution variable is available for the moment ref: https://cloud.google.com/cloud-build/docs/configuring-builds/substitute-variable-values

Now they are available as CloudBuild environment variables. From the official document:

Cloud Build provides the following GitHub-specific default substitutions available for pull request triggers:

$_HEAD_BRANCH : head branch of the pull request
$_BASE_BRANCH : base branch of the pull request
$_HEAD_REPO_URL : url of the head repo of the pull request
$_PR_NUMBER : number of the pull request

Not from Github API, but you can get the PR# from command line:

$ hub pr list -f "%I%n" -h "$(git rev-parse --abbrev-ref HEAD)"

In GitHub, a single branch can be associated with multiple Pull Requests.

You can look up all PRs associated with a given branch ref using the GitHub API: https://developer.github.com/v3/pulls/

Cloud Build does not currently provide the Pull Request information, but if it did this would probably come from something like the Check Suite data, which also treats PRs as a list.
