The Admin API uses secret API keys for authentication. All API requests must contain an Authorization header,
containing your secret key in the format specified by the Bearer Authentication
scheme:
Copy
Authorization: Bearer <PROFICIENT_SECRET_KEY>
You can create and delete secret keys in Project
Settings. Secret keys are strings
that start with sk_.
Never expose your project’s secret keys in the frontend (e.g. browser or
mobile apps). You should store your secret keys securely in your environment
secrets and never commit them to version control.
