Attribution reporting

The attributionSrc property of the HTMLAnchorElement interface gets and sets the attributionsrc attribute on an <a> element programmatically, reflecting the value of that attribute. attributionsrc specifies that you want the browser to send an Attribution-Reporting-Eligible header. On the server-side this is used to trigger sending an Attribution-Reporting-Register-Source header in the response, to register of a navigation-based attribution source.

The browser stores the source data associated with the navigation-based attribution source (as provided in the Attribution-Reporting-Register-Source response header) when it receives the navigation response.

See the Attribution Reporting API for more details.

Use cases

  • Use Attribution reporting

    Use Attribution reporting when standard HTML needs a more specific platform feature, semantic signal, or browser capability.

  • Handle edge cases

    Apply Attribution reporting to solve a focused requirement without redesigning the whole page architecture.

Cautions

  • Test Attribution reporting in your target browsers and input environments before depending on it as a primary behavior.
  • Provide a fallback path or acceptable degradation strategy when support is still limited.

Accessibility

  • Make sure Attribution reporting supports the intended task without making the page harder to perceive, understand, or operate.
