Quick start

This page describes a quick 3-step integration process.

Check out this link for a complete guide: Payment form integration.

Visualize the operating mode: Kinematics .

I. Create the formToken

  1. Authenticate with the REST API keys (more information: Step 2: Authenticate ).

  2. Use the Charge/CreatePayment Web Service with the payment data (amount, currency, order number, buyer details, etc.).

If you do not use the paymentMethods field then ALL eligible payment methods (currencies, technical constraints, etc.) associated with the store are offered (See: Selecting payment methods ). The description and all fields are available from our playground (menu on the left): Charge/CreatePayment .

  1. Retrieve theformToken(answer.formtokenfield) to display the payment form
{
    "status": "SUCCESS",
    "_type": "V4/WebService/Response",
    "webService": "Charge/CreatePayment",
    "applicationProvider": "LYRA",
    "version": "V4",
    "applicationVersion": "4.1.0",
    "answer": {
        "formToken": "DEMO-TOKEN-TO-BE-REPLACED",
        "_type": "V4/Charge/PaymentForm"
    }
}

The generated formToken is: Processing...

II. Displaying the form

Once the formToken has been generated:

  1. In the HEAD,
  • A. load our JavaScript library : src="https://static.lyra.com/static/js/krypton-client/V4.0/stable/kr-payment-form.min.js"

  • B. must include the public key in the kr-public-key parameter ( 3rd key in the REST API key table ).

  • C. include other initialization parameters , such as the kr-post-url-success parameter in case of successful payment.

  • D. Choose a theme (more information on Themes ).

You also have the choice :

  • Highlight a payment method.
  • Highlight several payment methods.

III. Analyzing the payment result

Analyze the payment result from the IPN or from the browser return. A la fin du paiement, vous pouvez analyser le résultat du paiement depuis :
  • instant payment notification: IPN: Analysis of the IPN (Notification URL) .
  • .

A security mechanism checks the authenticity of the transmitted information, with the kr-hash.

In the object ,PAYMENT,, an example of a kr-answer, :
