# Managing Vantage API clients

> Create and manage Vantage API Clients — the Client ID and Client Secret pairs that applications use to authenticate to the ABBYY Vantage API.

Applications authenticate to the ABBYY Vantage API using an **API Client** — a Client ID and Client Secret pair issued by your tenant. You can create multiple API clients so that each integrating application has its own credentials and flow settings.

<Note>
  Only a **Tenant Administrator** can create or manage API clients.
