# Manage live stream sources

Use the Wowza Streaming Engine™ [media server software](https://www.wowza.com/products/streaming-engine) REST API to create and manage encoders and cameras that publish live streams.

> **Notes:**
- Wowza Streaming Engine 4.3.0 or later is required.
- PHP examples for the tasks in this article are available in the **tests** folder of the [PHP REST Library for Wowza Streaming Engine on GitHub](https://github.com/WowzaMediaSystems/wse-rest-library-php).



## Get a list of live stream sources

View a list of the live stream sources (publishers) connected to a local instance of Wowza Streaming Engine:


```bash
curl -X GET \
-H 'Accept:application/json; charset=utf-8' \
-H 'Content-Type:application/json; charset=utf-8' \
http://localhost:8087/v3/servers/{serverName}/publishers
```

The command should return a response that looks like this:


```json
{
  "serverName": "serverName",
  "publishers": [{
    "publisher": "myRTSPcamera"
  }]
}
```

## Create a live stream source

Create a live stream source (publisher) for a local instance of Wowza Streaming Engine named *myRTMPencoder*:


```bash
curl -X POST \
-H 'Accept:application/json; charset=utf-8' \
-H 'Content-Type:application/json; charset=utf-8' \
http://localhost:8087/v3/servers/{serverName}/publishers \
-d '{
  "password": "123",
  "publisher": "myRTMPencoder",
  "serverName": "",
  "description": "",
  "version": "3"
}'
```

The command should return a response that looks like this:


```json
{
  "success": true,
  "message": "",
  "data": null
}
```

## Update a live stream source

Update a live stream source (publisher) named *myRTMPencoder* for a local instance of Wowza Streaming Engine:

-d '{
