Cross⁠-⁠domain iFrame Tracking

To enable cross-domain iFrame tracking, you need to add the crossdomain.enabled option to the tracker’s constructor, as shown below:

<iframe
  title="test"
  src="http://iframe1.website.com/iframe-path"
  width="300"
  height="300"
></iframe>

Add the crossdomain option following to your tracker constructor:

const tracker = new OpenReplay({
  projectKey: PROJECT_KEY,
  crossdomain: {
    enabled: true
  },
  captureIFrames: true
});

Then initialize the tracker instance inside the desired iFrame and add crossdomain.parentDomain to its constructor:

const tracker = new OpenReplay({
  projectKey: PROJECT_KEY,
  crossdomain: {
    // Specifies the domain of the parent window
    // If not specified, it will be set to '*'
    // Which means that child window will send messages to all domains inside the browser window
    // Consult your CSP settings to ensure that '*' is allowed or specify the parent domain
    parentDomain: '*',
    enabled: true
  }
});

Please note that if you’re using tracker snippet, we recommend using regular (openreplay.js) instance instead of openreplay-assist.js for child iframes (since assist session should connect to parent instance only).
