# User Authorization

The SDK supports interaction in both the **authorized** and **pre-authorization zones.** The application behavior depends on how token handling is implemented on the **host app** side.

**Scenarios:**

1. **Authorized zone:**

* The client is automatically identified.
* Full conversation history is available.

2. **Pre-authorization zone:**

* The client is considered unidentified.
