Polls

You can use the API to create and manage polls on live video broadcasts that have a status of LIVE. Polls are represented by VideoPoll objects and are comprised of VideoPollOptions, which represent possible answers to the poll question.

Create a Poll

To create a poll on a live video broadcast, send a request to:

POST /{live-video-id}/polls?question={question}&options={options}

The targeted LiveVideo object must have a status of LIVE in order for the VideoPoll to be created. Upon success, the API will respond with the VideoPoll object's ID.

Query String Parameters

  • {question} — The poll question.
  • {options} — An array of possible answers.

Refer to the Live Video Polls edge reference for a complete list of query string parameters you can include when creating a poll.
