 - **label** (Optional): The label to use to mark dependent issues. Default `dependent`.
 - **check_issues** (Optional): Enable checking for dependencies in issues. Enable by setting the value to `on`. Default `off`.
+- **ignore_dependabot** (Optional): Ignore dependabot PRs. Enable by setting the value to `on`. Default `off`. Use this if you run the action on `pull_request` rather than `pull_request_target`.
