Usage

Add the Authsignal component to your app. Generally, this should be placed at the root of your app.

import { Authsignal } from '@authsignal/react';

function App() {
  return (
    <div>
      <Checkout />
      <Authsignal tenantId="YOUR_TENANT_ID" baseUrl="YOUR_BASE_URL" />
    </div>
  );
}

Import the useAuthsignal hook in your component.

Then pass the challengeOptions returned from your server to the startChallenge function.

import { useAuthsignal } from '@authsignal/react';

export function Checkout() {
  const { startChallenge } = useAuthsignal();

  const handlePayment = async () => {
    const response = await fetch('/api/payment', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
    });

    const data = await response.json();

    if (data.challengeOptions) {
       startChallenge({
          challengeOptions: data.challengeOptions,
          onChallengeSuccess: ({ token }) => {
            // Challenge was successful
          },
          onCancel: () => {
            // User cancelled the challenge
          },
          onTokenExpired: () => {
            // Token expired
          },
        });
    }
  };

  return (
    <div>
      <button type="button" onClick={handlePayment}>Pay</button>
    </div>
  );
}

Alternatively, you can use the startChallengeAsync function to work with promises.

import { useAuthsignal, ChallengeError } from '@authsignal/react';

export function Checkout() {
  const { startChallengeAsync } = useAuthsignal();

  const handlePayment = async () => {

    const response = await fetch('/api/payment', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
    });

    const data = await response.json();

    if (data.challengeOptions) {
      try {
        const { token } = await startChallengeAsync({
          challengeOptions: data.challengeOptions,
        });

        // Challenge was successful
      } catch (e) {
        if (e instanceof ChallengeError) {
          if (e.code === "USER_CANCELED") {
            // User cancelled the challenge
          } else if (e.code === "TOKEN_EXPIRED") {
            // Token expired
          }
        }
      }
    }
  };

  return (
    <div>
      <button type="button" onClick={handlePayment}>Pay</button>
    </div>
  );
}
