# Group badges API

> [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/17082)
in GitLab 10.6.

## Placeholder tokens

Badges support placeholders that will be replaced in real time in both the link and image URL. The allowed placeholders are:

- **%{project_path}**: will be replaced by the project path.
- **%{project_id}**: will be replaced by the project id.
- **%{default_branch}**: will be replaced by the project default branch.
- **%{commit_sha}**: will be replaced by the last project's commit sha.

Because these enpoints aren't inside a project's context, the information used to replace the placeholders will be
from the first group's project by creation date. If the group hasn't got any project the original URL with the placeholders will be returned.
