Documentation

Integration without surprises

An overview of how technical integration with Klirio works. The full API reference and test credentials are provided after your application is approved.

Integration options

Payment page

Your server creates a payment and redirects the customer to a ready-made payment page. The minimum of development on your side.

API

Create payments, check statuses, issue refunds and send payouts from your own backend.

How a payment works

  1. 1

    Create

    Your server creates a payment and receives a link to the payment page.

  2. 2

    Pay

    The customer chooses a payment method and pays.

  3. 3

    Notify

    Klirio sends a notification with the result to your server.

  4. 4

    Confirm

    You confirm the order and show the result to the customer.

Test mode

Every project starts in test mode. You can run through the full payment flow with test payments, check notifications and error handling — without real money.

Technical information

  • Requests are sent over HTTPS
  • Each project has its own keys for request authentication
  • Notifications are signed so you can verify the sender
  • Clear payment statuses and error codes
