Quick start

Add Watenga.js to your site in three lines:

typescript

// Server (secret key): the amount is decided here
const session = await watenga.checkoutSessions.create({ amount: '25.00', currency: 'USD', reference: 'ORD-1001' });

// Browser (publishable key): pays that session
Watenga('pk_test_your_publishable_key').mount('#pay', {
  clientSecret: session.client_secret, amount: 25.00, currency: 'USD', reference: 'ORD-1001',
  onSuccess: (txn) => console.log(txn.id),
});
