## Upload media as an attachment (async) {#v2}
```http
POST /api/v2/media HTTP/1.1

**OAuth:** User token + `write:media`\
**Version history:**\
3.1.3 - added\

4.0.0 - Smaller media formats (image) will be processed synchronously and return 200 instead of 202. Larger media formats (video, gifv, audio) will continue to be processed asynchronously and return 202.

## (DEPRECATED) Upload media as an attachment {#v1}
```http
POST /api/v1/media HTTP/1.1
```
Creates an attachment to be used with a new status. This method will return after the full sized media is done processing.
**Returns:** [MediaAttachment]({{< relref "entities/MediaAttachment" >}})\
**OAuth:** User token + `write:media`\
**Version history:**\
0.0.0 - added\
2.3.0 - add `focus` parameter\
3.1.3 - deprecated in favor of [POST /api/v2/media](#v2), which is equal to v1 in all aspects, except it returns HTTP 202, and the returned JSON object has a url of null. This is because while the thumbnail is prepared synchronously, the full version of the media attachment will be processed in the background.\
3.2.0 - add `thumbnail` parameter
#### Request
