Query a live stream using the Wowza Video REST API

Learn how to use the Wowza Video™ service's REST API to gather information about an existing live stream, to update the live stream, and to delete the live stream.

Start the live stream

Before using the Wowza Video REST API to query and update a live stream, create and start a live stream with the user interface.

1. If you haven't already added a live stream, see Get started with Wowza Video to learn how to add one. You'll need the JWT for API authentication that you created in that tutorial to complete this tutorial. See Authentication for more information.
2. To start the live stream in Wowza Video, select Available Streams , select the stream on the Live Streams page, and then click Start Live Stream at the top of the Live Stream Detail page.

Query for information about the live stream

Now that you have a live stream that's started, use the following example requests to find information about the live stream. Example requests are presented in curl using environment variables, but you can also use a GUI REST client for API testing such as Postman or Paw.

If you have basic questions about using a REST API, start with About the Wowza Video REST API.

• Query for all live streams in your account to find the details of your existing live stream. You'll need the ID of your live stream to do additional requests.

  Fetch all live streams:

  Copy

  Copied

  curl -X GET \
  -H "Authorization: Bearer ${WV_JWT}" \
  "${WV_HOST}/api/${WV_VERSION}/live_streams"

• View a live stream's state:
  Copy

  Copied

  curl -X GET \
  -H "Authorization: Bearer ${WV_JWT}" \
  "${WV_HOST}/api/${WV_VERSION}/live_streams/[live_stream_id]/state"

  Possible live stream states are starting, stopping, started, stopped, and resetting.

• View the details of a running live stream:
  Copy

  Copied

  curl -X GET \
  -H "Authorization: Bearer ${WV_JWT}" \
  "${WV_HOST}/api/${WV_VERSION}/live_streams/[live_stream_id]/stats"

• View a live stream's preview image:
  Copy

  Copied

  curl -X GET \
  -H "Authorization: Bearer ${WV_JWT}" \
  "${WV_HOST}/api/${WV_VERSION}/live_streams/[live_stream_id]/thumbnail_url"

Update the live stream

Use the following example request to update the name of the live stream. You don't have to stop the live stream to update its configuration.

• Update a live stream's configuration:
  Copy

  Copied

  curl -X PATCH \
  -H "Authorization: Bearer ${WV_JWT}" \
  -d '{
     "live_stream": {
       "name": "MyDifferentLiveStreamName"
     }
  }' "${WV_HOST}/api/${WV_VERSION}/live_streams/[live_stream_id]"

  -H "Authorization: Bearer ${WV_JWT}" \
  "${WV_HOST}/api/${WV_VERSION}/live_streams/[live_stream_id]/stop"

• Delete the live stream:
