import { GraphQLClient, gql } from 'graphql-request';

const API_URL = 'https://transactional-graph.staging.fluzapp.com/api/v1/graphql';

const REVEAL_VIRTUAL_CARD = gql`
  mutation RevealVirtualCardByVirtualCardId {
    revealVirtualCardByVirtualCardId(
      virtualCardId: "c107e50b-10f3-449c-92c0-609d9a8cfa2a"
    ) {
      cardNumber

      cvv
      cardHolderName
      billingAddress {
        streetAddress
        postalCode

const client = new GraphQLClient(API_URL, {
  headers: {
    Authorization: `Bearer <<USER_ACCESS_TOKEN>>`,
    'Content-Type': 'application/json',
  },

const response = await client.request(REVEAL_VIRTUAL_CARD);
