Managing Vantage API Clients
Manage 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.
