# Ecommerce authorization flow

> Availability of Onboarding data to the Ecommerce authorization flow.

When each entity is registered through the Onboarding API, its regulatory data is automatically synchronized with TransactionKeyDB through EventBridge.

    O["Onboarding API<br/>Entity registration"] --> E["EventBridge"]
    E --> T["TransactionKeyDB<br/>Processing account"]
    T --> A["Ecommerce authorization<br/>Acquirer and merchant data available"]
```

The synchronization makes the acquirer information, including BINs and institution codes, and merchant information available to Ecommerce authorization without manual intervention.
