React SDK

Pre-built React components for integrating Reevit payments with beautiful, customizable checkout UI.

Installation

npm install @reevit/react

Quick Start

The simplest way to integrate Reevit is using the ReevitCheckout component.

import { ReevitCheckout } from '@reevit/react';
import '@reevit/react/styles.css';

function App() {
  return (
    <ReevitCheckout
      publicKey="pfk_test_your_key.secret"
      amount={10000} // Amount in smallest unit (pesewas for GHS)
      currency="GHS"
      email="customer@example.com"
      reference={`ORD-${Date.now()}`}
      onSuccess={(result) => {
        console.log('Payment success!', result);
        alert(`Payment of ${result.currency} ${result.amount/100} successful!`);
      }}
      onError={(error) => {
        console.error('Payment failed:', error.message);
      }}
    >
      <button className="my-pay-button">Pay GHS 100.00</button>
    </ReevitCheckout>
  );
}

Note: Always import the styles CSS file to get the built-in checkout modal styling.

Theming

Customize the checkout widget to match your brand:

<ReevitCheckout
  publicKey="pfk_test_xxx.secret"
  amount={5000}
  currency="GHS"
  theme={{
    primaryColor: '#6200EE',
    backgroundColor: '#F5F5F5',
    textColor: '#000000',
    borderRadius: '12px',
    fontFamily: "'Segoe UI', Roboto, sans-serif",
    darkMode: true,
  }}
  onSuccess={handleSuccess}
>
  <button>Secure Checkout</button>
</ReevitCheckout>

Theme Options

Property	Type	Description
`primaryColor`	`string`	Primary button and accent color
`backgroundColor`	`string`	Modal background color
`textColor`	`string`	Text color
`borderRadius`	`string`	Border radius for buttons and inputs
`fontFamily`	`string`	Custom font family
`darkMode`	`boolean`	Enable dark mode styling

Controlled Mode

If you prefer to create the payment intent on your backend before opening the checkout, you can use Controlled Mode.

<ReevitCheckout
  publicKey="pfk_test_xxx.secret"
  initialPaymentIntent={myPreCreatedIntent}
  onSuccess={handleSuccess}
>
  <button>Open Pre-paid Checkout</button>
</ReevitCheckout>

In this mode, the SDK skips the initial intent creation step and proceeds directly to payment method selection or provider confirmation.

For full control over the payment flow, use the useReevit hook to build your own custom UI.

import { useReevit } from '@reevit/react';

function CustomCheckout() {
  const {
    status,        // 'idle' | 'loading' | 'ready' | 'method_selected' | 'processing' | 'success' | 'failed'
    paymentIntent, // Created payment intent details
    error,         // Error object if failed
    initialize,    // Start the checkout process
    selectMethod,  // Pick 'card' or 'mobile_money'
    processPayment,// Confirm payment with PSP data
    reset,         // Reset to initial state
    isLoading,     // Loading state boolean
  } = useReevit({
    config: {
      publicKey: 'pfk_test_xxx.secret',
      amount: 5000,
      currency: 'GHS',
      email: 'customer@example.com',
    },
    apiBaseUrl: 'http://localhost:8080', // Optional: for local development
    onSuccess: (result) => console.log('Payment complete!', result),
    onError: (error) => console.error('Payment failed:', error),
  });

  if (status === 'loading') return <div>Loading...</div>;
  if (status === 'success') return <div>Payment successful! ✅</div>;

  return (
    <div>
      {status === 'idle' && (
        <button onClick={() => initialize()}>Start Checkout</button>
      )}
      
      {status === 'ready' && (
        <>
          <h3>Select Payment Method</h3>
          <button onClick={() => selectMethod('card')}>💳 Card</button>
          <button onClick={() => selectMethod('mobile_money')}>📱 Mobile Money</button>
        </>
      )}
      
      {error && (
        <div className="error">
          {error.message}
          <button onClick={reset}>Try Again</button>
        </div>
      )}
    </div>
  );
}

PSP Bridges

For advanced use cases, use individual PSP bridges directly.

Paystack Bridge

The default bridge for card and mobile money payments in Ghana/Nigeria:

import { PaystackBridge } from '@reevit/react';

<PaystackBridge
  publicKey="pfk_test_xxx.secret"
  email="customer@example.com"
  amount={5000}
  currency="GHS"
  reference="TXN_12345"
  channels={['card', 'mobile_money']}
  onSuccess={(result) => console.log('Paid:', result)}
  onError={(err) => console.error(err.message)}
  onClose={() => console.log('Closed')}
/>

Stripe Bridge

For card payments including Apple Pay and Google Pay:

import { StripeBridge } from '@reevit/react';

<StripeBridge
  publishableKey="pfk_test_xxx.secret"
  clientSecret="pi_xxx_secret_xxx" // From your backend
  amount={5000}
  currency="USD"
  reference="your_unique_reference"
  onSuccess={(result) => console.log('Paid:', result.paymentIntentId)}
  onError={(err) => console.error(err.message)}
/>

Monnify Bridge (Nigeria)

For bank transfers and cards in Nigeria:

import { MonnifyBridge } from '@reevit/react';

<MonnifyBridge
  apiKey="MK_TEST_xxx"
  contractCode="1234567890"
  amount={5000}
  currency="NGN"
  reference="TXN_12345"
  customerName="John Doe"
  customerEmail="john@example.com"
  isTestMode={true}
  onSuccess={(result) => console.log('Paid:', result.transactionReference)}
  onError={(err) => console.error(err.message)}
/>

M-Pesa Bridge (Kenya/Tanzania)

M-Pesa uses STK Push - the customer receives a prompt on their phone:

import { MPesaBridge, useMPesaStatusPolling } from '@reevit/react';

function MpesaPayment() {
  const [checkoutId, setCheckoutId] = useState(null);
  
  const { startPolling } = useMPesaStatusPolling(
    '/api/mpesa/status',
    checkoutId,
    {
      onSuccess: (result) => console.log('Paid:', result.transactionId),
      onFailed: (err) => console.error(err.message),
      onTimeout: () => console.log('Timed out'),
    }
  );

  return (
    <MPesaBridge
      apiEndpoint="/api/mpesa/stk-push"
      phoneNumber="254712345678"
      amount={500}
      currency="KES"
      reference="TXN_12345"
      onInitiated={(id) => {
        setCheckoutId(id);
        startPolling();
      }}
      onSuccess={(result) => console.log('Paid!')}
      onError={(err) => console.error(err.message)}
    />
  );
}

Troubleshooting

CORS Errors

If you see CORS errors when connecting to your local backend:

Ensure your backend includes your frontend origin in FRONTEND_ALLOWED_ORIGINS
Check that the apiBaseUrl prop points to the correct backend URL
Verify your API key is valid and registered in the database

Styles Not Loading

Make sure you import the styles:

import '@reevit/react/styles.css';

Payment Failed: Network Error

This usually means the SDK cannot reach the backend:

Check your apiBaseUrl is correct
Ensure the backend is running
For test keys (pfk_test_*), the SDK defaults to sandbox API unless apiBaseUrl is set
