# Authorization

#### **PreShared Key (PSK) Authorization**

To begin, clients must obtain a PreShared Key (PSK) for authorization. This key can be found in the application's user interface (UI). It is crucial to save the PSK immediately upon retrieval, as it is displayed only once and cannot be retrieved again.

### **Authorization**

Clients must use the PSK obtained from the UI for authorization. Include the PSK in the header of your data submission requests as follows:

```html
Authorization: Bearer YOUR_PRESHARED_KEY
```
