Learn Video API with Kaltura's Public API Docs

Kaltura's Video Platform as a Service (PaaS) offers an extensive public API that can be accessed using various programming languages. In this blog post, we'll focus on using JavaScript to access Kaltura's Video PaaS API.

Getting Started

Before we dive into specific examples, you'll need to obtain an API key from Kaltura. You can do this by following these instructions.

Once you've obtained your API key, you'll be able to use the API endpoint https://www.kaltura.com/api_v3/ to access the various API actions.

Uploading a Video

One of the most essential features of Kaltura's Video PaaS is uploading videos. To upload a video using JavaScript, you'll need to use the XMLHttpRequest object to make a POST request to the designated API action.

const xhr = new XMLHttpRequest();
xhr.open("POST", "https://www.kaltura.com/api_v3/?service=uploadtoken&action=add", true);

const formData = new FormData();
formData.append("format", "1");
formData.append("ks", "INSERT_YOUR_API_KEY_HERE");

xhr.onreadystatechange = () => {
  if (xhr.readyState === XMLHttpRequest.DONE) {
    console.log(xhr.responseText);
  }
};

xhr.send(formData);

Retrieving Data

You can also use JavaScript to retrieve data from Kaltura's Video PaaS. For example, if you want to retrieve a list of all categories on your account, you can make a GET request to the API endpoint with the service parameter set to category and the action parameter set to list.

const xhr = new XMLHttpRequest();
xhr.open("GET", "https://www.kaltura.com/api_v3/?service=category&action=list&ks=INSERT_YOUR_API_KEY_HERE");

xhr.onreadystatechange = () => {
  if (xhr.readyState === XMLHttpRequest.DONE) {
    console.log(xhr.responseText);
  }
};

xhr.send();

Updating Data

JavaScript can also be used to update data on Kaltura's Video PaaS platform. For example, if you want to update the name of a specific video, you can make a POST request to the media API action update with the ID of the video and the new name.

const xhr = new XMLHttpRequest();
xhr.open("POST", "https://www.kaltura.com/api_v3/?service=media&action=update&entryId=INSERT_VIDEO_ID_HERE&name=NEW_VIDEO_NAME&ks=INSERT_YOUR_API_KEY_HERE", true);

xhr.onreadystatechange = () => {
  if (xhr.readyState === XMLHttpRequest.DONE) {
    console.log(xhr.responseText);
  }
};

xhr.send();
