Environment Variables

GITLAB_API_URL=https://your-gitlab-instance.com
GITLAB_TOKEN=your_access_token

# Optional: Provide a mapping from usernames to user IDs (JSON string)
# This can reduce API calls, especially when referencing the same users frequently

# Optional: Provide a mapping from project names to project IDs (JSON string)
# Project IDs can be numbers or strings (e.g., 'group/project')
# This can reduce API calls and ensure the correct project is used
# Example: '{"project-name-a": 1001, "group/project-b": "group/project-b"}'
GITLAB_PROJECT_MAPPING={"project-name-a": 1001, "group/project-b": "group/project-b"}
