# Project 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.
