New business sandbox

Sandbox rules

The sandbox should mirror production structure without moving real money or sending real notifications.

• Use test keys and test accounts only.
• Keep customer data synthetic.
• Reset the workspace between experiments.

Safe testing

Try the onboarding flow, payment flow, and webhook flow before turning anything on in production.

const session = await kopo.checkout.create({
  mode: 'payment',
  success_url: 'https://example.com/success',
  test_mode: true,
});
