Security best practices
- Store API keys in environment variables, not in source code.
- Use a separate key per environment (development, staging, production).
- Rotate keys periodically and deactivate unused ones.
- Keys are scoped to a single company. All resources accessed through a key belong to that company.
Error responses
If authentication fails, the API returns a401 status code.
