|
| 36 | ### How do I send GIFs?
|
| 37 |
|
| 38 | You might be trying to send your animated GIFs using *TelegramBot#sendPhoto()*.
|
| 39 | The method mostly supports static images. As noted by the community,
|
| 40 | it seems you need to send them as documents, using *TelegramBot#sendDocument()*.
|
| 41 |
|
| 42 | ```js
|
| 43 | bot.sendDocument(chatId, 'cat.gif');
|
| 44 | ```
