Parameters

PropertyTypeDescriptionRequired
Enable frontend-backend linking via W3C trace context
enabled		boolean

When enabled, the RUM JavaScript includes the W3C trace context in XHR and Fetch requests.

Required
Cross-origin URL pattern
crossOriginUrlPattern		text

Specify a regular expression to match Fetch and XHR URLs for cross-origin requests. When the pattern matches, the traceparent and tracestate request headers are added to link the request with backend traces.

Important: Endpoints must implement CORS handling that allows the traceparent and tracestate request headers. Otherwise, requests will fail and break your application!
