Define a JavaScript function in your script file

<script>
      // Callback for handling transaction status
      const callWhenDone = (data) => {
        if (data.status === "success") {
          console.log("Payment successful", data);
        } else if (data.status === "failed") {
          console.error("Payment failed", data);
        }
      };

      // Payment configuration and initialization
      const payWithKlasha = () => {
        const MERCHANT_KEY = "{{merchantKey}}";
        const AMOUNT = 1;
        const BUSINESS_ID = "{{businessId}}";
        const ENVIRONMENT = true; // true for dev, false for production
        const currency = "{{currency}}";
        const DESTINATION_CURRENCY = "{{destinationCurrency}}";
        const DESCRIPTION = "school fee";

        const paymentKit = {
          tx_ref: "{{paylink_ref}}",
          fullname: "{{fullname}}",
          firstName: "{{firstName}}",
          lastName: "{{lastName}}",
          email: "{{email}}",

          businessId: BUSINESS_ID,
          merchantKey: MERCHANT_KEY,
          amount: AMOUNT,
          sourceAmount: "1",
          rate: 1,
        };

        const client = new KlashaClient(
          MERCHANT_KEY,
          BUSINESS_ID,
          AMOUNT,
          DESCRIPTION,
          callWhenDone,
          currency,
          DESTINATION_CURRENCY,
          paymentKit,
          ENVIRONMENT
        );

        client.init();
      };

      document.addEventListener("DOMContentLoaded", payWithKlasha);
    </script>
