+# Group badges API
+
+## 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.
