It's now possible to obtain this information directly from CodeBuild environmental variables:

• CODEBUILD_WEBHOOK_BASE_REF: The base reference name of the webhook event that triggers the current build. For a pull request, this is the branch reference.
• CODEBUILD_WEBHOOK_HEAD_REF: The head reference name of the webhook event that triggers the current build. It can be a branch reference or a tag reference.
• CODEBUILD_WEBHOOK_TRIGGER: Shows the webhook event that triggered the build. This variable is available only for builds triggered by a webhook. The value is parsed from the payload sent to CodeBuild by Github, Github Enterprise, or Bitbucket. The value's format depends on what type of event triggered the build.
  • For builds triggered by a pull request, it is pr/pull-request-number.
  • For builds triggered by creating a new branch or pushing a commit to a branch, it is branch/branch-name.
  • For builds triggered by a pushing a tag to a repository, it is tag/tag-name.
