# Update Transcoder

```
PUT 
/api/transcoders/:transcoderId
```

Make changes to the configuration of an existing Transcoder. Changes should take effect without requiring a server restart except for DNS prefix and cluster, which can only be updated when the transcoder is in a shutdown state.

Changing the profile will require either a profile id or the height, frameRate, and passThrough. If you specify both, only the profile will be used. See the 'List Transcoder Profiles' endpoint to find available Transcoder profiles.
