Link Icon Presets¶

Icons shown next to the Bot / Channel / Support links in the subscription card (liteMode mode). The provider picks an icon by key from a preset set — each platform (Android, iOS, Desktop) maps that key to its own native icon.

Why this approach instead of an image URL:

Consistent appearance across all platforms — icons from the system set (Material Icons, SF Symbols) adapt to the theme.
Zero network requests in the client — the key is just a string in settings.
Offline support — the app works even without a server connection.

Where it's set¶

The provider picks the icon in the web panel for each domain in the Lite Mode block. Values are stored in SubscriptionSettings:

Field	Type	Description
`botIconKey`	`string?`	Icon key for `botUrl`
`channelIconKey`	`string?`	Icon key for `channelUrl`
`supportIconKey`	`string?`	Icon key for `supportUrl`

Returned to the client through the Premium API in the settings object.

Client behavior¶

Key set and known → the client renders the corresponding native icon.
Key empty (null / "") → fallback to the slot's default icon:
botUrl → send (paper plane)
channelUrl → megaphone (bullhorn)
supportUrl → help (question mark)
Key set but unknown to the client (old app version + new key) → fallback to the same default.

Full preset list¶

20 keys in total. The key name is stable — once a key is published it is never renamed.

Example¶

{
  "settings": {
    "liteMode": true,
    "botUrl": "https://t.me/my_bot",
    "botIconKey": "bot",
    "channelUrl": "https://t.me/my_channel",
    "channelIconKey": "megaphone",
    "supportUrl": "https://t.me/my_support",
    "supportIconKey": "lifebuoy"
  }
}

In the subscription card the user will see three buttons: robot (bot), bullhorn (channel), lifebuoy (support).
