**How do I send GIFs?**

You might be trying to send your animated GIFs using *TelegramBot#sendPhoto()*.
The method mostly supports static images. As noted by the community,
it seems you need to send them as documents, using *TelegramBot#sendDocument()*.


```js
bot.sendDocument(chatId, "cat.gif");
```
