How to get querystring values in Action Files

I have a URL as below with various query string values.

http://localhost:3000/product/?id=123&name=test

I am using your code for isomorphic application using redux, react. So i am firing action and may i know how can i get these query string values to redux action file?

export function getProductData(params) {

debug('Action Requested:' + params);

return {
type: GET_PRODUCT_DATA,
promise: request.get(API_URL + params.productId)
}
};
Because in action i am firing the API call and i need that ID from querystring value.
