How to use

Instantiation

First of all, we must instantiate the SDK.

Keep in mind that the SDK can be instantiated only once, and it is a requirement to be able to use all its methods.

In order to instantiate the SDK we need to specify the public key and the environment.

Retrieving your publicKey

Before instantiating the SDK make sure to retrieve your publicKey. This can be done by: Logging into the Merchant Panel, going into Settings > API Access, under your Read Only Credentials you will find your API Public key.

• npm

import SDK from '@d24/sdk';

new SDK('as1i2nxal12bvd', { environment: 'stg' });

• umd

new window.D24.SDK('as1i2nxal12bvd', { environment: 'stg' });

How to use the constructor SDK(publicKey, options)

Required parameters

CreditCardForm

Fonts

Add the following fonts to your project (inside index.html or any main html):

<link rel="preconnect" href="https://fonts.googleapis.com" />
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin />
<link
  href="https://fonts.googleapis.com/css2?family=Roboto:ital,wght@0,100;0,300;0,400;0,500;0,700;0,900;1,100;1,300;1,400;1,500;1,700;1,900&display=swap"
  rel="stylesheet"
/>

Form

After instantiating the SDK, we will be able to use the CreditCardForm component.

<CreditCardForm
        authToken="PAYMENT_TOKEN"
        country="COUNTRY_ISO2"
        onTokenGenerationError={handleTokenErrorCallback}
        onBack={handleGoBack}
        onSuccess={handleSuccess}
        onError={handleError}
/>

}

onTokenGenerationError

function handleTokenErrorCallback(error: string) {
  console.log(error);
}

onBack

This callback function will be executed when the user clicks on the Go Back button.

function handleGoBackCallback() {
  console.log('Go back');
}

This callback function will be executed when the payment is successful.

function handleSuccessCallback(successUrl: string) {
  console.log('Success:', successUrl);
}

onError

function handleErrorCallback(errorUrl: string) {
  console.log('Error:', errorUrl);
}

theme

This is a custom version of the theme to give a different style that fits with the client's UI. To customize the colors, you can add a colorSchema object as shown in the example. You don't need to pass the entire object; you can add only the parts you want to change.
