## Authentication

All API calls require authentication via the `X-Bunker-Token` header. For multi-tenant setups, use the `X-Bunker-Tenant` header to specify the tenant context.

### Multi-Tenant Usage

Multi-tenancy is supported when DataBunker Pro is configured to work with PostgreSQL database. **Note:** DataBunker Pro supports both PostgreSQL and MySQL (Percona) as backend databases, but multi-tenancy requires PostgreSQL and is not available with MySQL.

When using DataBunker Pro in a multi-tenant environment:

* **Single Tenant**: Omit the `X-Bunker-Tenant` header (default behavior)
* **Multi-Tenant**: Include `X-Bunker-Tenant: your-tenant-name` header

**Example:**

```bash theme={null}
# Single tenant
curl -X POST http://localhost:3000/v2/UserCreate \
  -H "X-Bunker-Token: your-token" \
  -d '{"profile":{"login":"user1"}}'

# Multi-tenant
curl -X POST http://localhost:3000/v2/UserCreate \
  -H "X-Bunker-Token: your-token" \
  -H "X-Bunker-Tenant: acme-corp" \
  -d '{"profile":{"login":"user1"}}'
```

## Base URL

The API is available at `/v2/` endpoint with all requests using POST method.
