### Settings

**Datastream (optional)** - choose the Datastream if you plan to use `setProperty` API.

**Show icon** - To show/hide the “Clock” icon on the left.

**Show label** - To show/hide the “Last reported” text.

### **Properties you can change**

You can hide/show header widgets from device. Use `isHidden` property API:

```
Blynk.setProperty(vPin, "isHidden", "propertyValue");
```

Where:

`vPin` is: virtual pin number the widget is assigned to

`isHidden`: property that controls the widget visibility

`propertyValue`: value of the property you want to change. *true* and *false* values are supported.

Example:

```
Blynk.setProperty(V12, "isHidden", true); // This will hide the widget
```

{% hint style="warning" %}
Don't put **`Blynk.setProperty()`** into the **`void loop()`** as it can cause a flood of messages and your hardware will be disconnected. Send such updates only when necessary, or use timers.
{% endhint %}

### Change widget properties via HTTPs API

{% hint style="info" %}
Updates the Datastream Property and all assigned Widgets!
{% endhint %}

<mark style="color:blue;">`GET`</mark> `https://{server_address}/external/api/update/property?token={your 32 char token}&pin={your vPin}&{property}={value}`

The endpoint allows you to update the Datastream Property value via GET request. All widgets (both web and mobile) that are assigned to this datastream will inherit this property. The Datastream Property is persistent and will be stored forever until you change it with another value. In order to clear the property you need to clear the device data in device actions menu.

**Example:**\
`https://blynk.cloud/external/api/update/property?token=GVki9IC70vb3IqvsV0YD3el4y0OpneL1&pin=V1&isHidden=true`
