# bots.getPreviewInfo

Bot owners only, fetch [main mini app preview information, see here »](/api/bots/webapps.md#main-mini-app-previews) for more info.

Note: technically non-owners may also invoke this method, but it will always behave exactly as [bots.getPreviewMedias](/method/bots.getPreviewMedias.md), returning only previews for the current language and an empty `lang_codes` array, regardless of the passed `lang_code`, so please only use [bots.getPreviewMedias](/method/bots.getPreviewMedias.md) if you're not the owner of the `bot`.

```tl
bots.previewInfo#ca71d64 media:Vector<BotPreviewMedia> lang_codes:Vector<string> = bots.PreviewInfo;
---functions---
bots.getPreviewInfo#423ab3ad bot:InputUser lang_code:string = bots.PreviewInfo;
```
