How does Core Checkout work?

What is Core Checkout?

Core Checkout lets you accept payments on your website or app through our API. When your customer clicks “Pay”, they are redirected to a payment page hosted by Core, then sent back to your website after confirmation. You choose which payment methods to display: bank card, Apple Pay and Carlo App.


  • Integration requires a developer. Our technical documentation covers the full process.
  • Core Checkout also lets you save a customer’s card and charge it later. See What can you do with Core Checkout? for the full picture.


How does a payment work?

  1. Your customer clicks "Pay" on your website
  2. They are redirected to the Core-hosted payment page
  3. They enter their card details and confirm the payment
  4. They are automatically redirected back to your website
  5. You receive a real-time confirmation in your dashboard

Payouts

  • Funds are paid out at D+3, counted in business days (no Saturday or Sunday)
  • The bank transfer takes an additional 1 to 2 business days
  • You receive the funds in your account between D+4 and D+5
  • Card and Apple Pay fees (2% + €0.20 per transaction) are automatically deducted from the payout, with no separate invoice. Carlo App payments use your existing Carlo App rate.


💡 Good to know — card and Apple Pay payments can be cancelled in full before the payout. Carlo App payments are refunded from the Carlo Business dashboard.
