[Vuejs]-Paytm JS Checkout integration with vue JS front end

I used script in header method like this,

head() {
    return {
      script: true
        ? [{ src: "https://checkout.razorpay.com/v1/checkout.js" }]
        : [{ src: "https://checkout.razorpay.com/v1/razorpay.js" }],
      // script: [{ src: "https://checkout.razorpay.com/v1/checkout.js" }],
    };
  }
