getBrowserData

const getBrowserData: () => ThreeDSBrowserData;

Collects the browser information a 3DS authentication request needs.

These are the JS-reachable EMVCo browserInformation fields; browserIP and browserAcceptHeader are filled in server-side from the request itself. Pass the result to your backend along with the vault form token so it can build the authentication request.

Field names are the EMVCo ones — for the browser node of POST /v2/payments, map them with toPaymentBrowserNode.

Returns​

ThreeDSBrowserData

Example​

const { vault_form_token } = await secureFields.submit();
await fetch('/checkout/authenticate', {
  method: 'POST',
  body: JSON.stringify({ vault_form_token, browser: toPaymentBrowserNode() }),
});
