React Integration

1. Install the React SDK (Install guide):

   npm install @thirdweb-dev/react

   yarn add @thirdweb-dev/react
2. On your frontend, render the CheckoutWithCard component with your configs.

Example code

import { CheckoutWithCard } from "@thirdweb-dev/react";

<CheckoutWithCard
  clientId="YOUR_CLIENT_ID"
  configs={{
    // Registered contract ID
    contractId: "YOUR_CONTRACT_ID",
    // Buyer wallet address
    walletAddress: "0x...",
    // Mint method (for custom contracts only)
    mintMethod: {
      name: "claimTo",
      args: {
        _to: "$WALLET",
        _quantity: "$QUANTITY",
        _tokenId: 0,
      },
      payment: {
        value: "0.1 * $QUANTITY",
        currency: "ETH",
      },
    },
  }}
  onPaymentSuccess={(result) => {
    console.log("Payment successful:", result);
  }}
/>;

Javascript Integration

1. Install the Javascript SDK with your preferred package manager.
   • npm install @thirdweb-dev/payments
   • yarn add @thirdweb-dev/payments
2. Call createCheckoutWithCardElement to insert the iframe on your page. Pass the configs to this component.
   1. If you don't provide elementOrId, this call returns an iframe element for you to insert into your page.

Example code

import { createCheckoutWithCardElement } from "@thirdweb-dev/payments";

// Assume a container exists:
//
//      <div id="paper-checkout-container" width="380px" />
//
createCheckoutWithCardElement({
  clientId: "YOUR_CLIENT_ID",
  configs: {
    contractId: "YOUR_CONTRACT_ID",
    walletAddress: "0x...",
  }
  elementOrId: "paper-checkout-container",
  appName: "My Web3 App",
  options,
  onError(error) {
    console.error("Payment error:", error);
  },
  onPaymentSuccess({ id }) {
    console.log("Payment successful.");
  },
});

// Alternatively, insert the iframe programmatically:
//
//      const iframe = createCheckoutWithCardElement(...)
//      document.getElementById('paper-checkout-container').appendChild(iframe);

Important Notes

How do I prevent the 3D Secure or KYC modal from popping up behind my other frontend components?

The SDK uses a z-index of 10000 for these modals. If they are appearing behind other components, please lower your other components' z-index values.
