  showLoading: true,
})

Form of the issuer

yuno.startCheckout({
  issuersFormEnable: true,
})

Mode of form rendering

yuno.startCheckout({
  renderMode: {
    type: 'modal',
    elementSelector: '#form-element',
  },
})

Card form configurations

yuno.startCheckout({
  card: {
    type: "extends",
    styles: '',
    cardSaveEnable: false,
    texts: {}
  },
})

Text payment form buttons

yuno.startCheckout({
  texts: {
    customerForm?: {
      submitButton?: string;
    }
    paymentOtp?: {
      sendOtpButton?: string;
    }
  }
})

Persist credit card form to retry payments

If a transaction is rejected, you can use the credit card form to retry a payment after the customer has entered the credit card details. To do that, you will need to:

1. Add the following parameter while initializing the SDK to persist the credit card form after the one-time use token is created:
   JavaScript

   yuno.startCheckout({
     automaticallyUnmount: false,
   })
   

2. In case the transaction is rejected, you will need to:
   1. Execute the method yuno.notifyError() to delete the previously entered CVV for the first transaction.
   2. Create a new checkout session and update the SDK with the new one by executing yuno.updateCheckoutSession(checkoutsession)
3. Continue with the new checkout and one-time use token with the regular payment flow.

Hide Pay button

You can hide the Pay button when presenting the Card or Customer Data Forms. To control this feature, you'll set showPayButton to false when starting the checkout with the startCheckout function. The code block below presents an example of how to hide the payment button:

yuno.startCheckout({
  /**
   * Hide (false) or show (true) the customer or card form pay button
   * @default true
   * @optional
   */
  showPayButton: false,
})

The following images present examples of the Customer Data Form with and without the Pay button:

The following images present examples of the Card Form with and without the Pay button:

If you hide the Pay button, you will need to start the OTT creation through your code. To create the OTT and continue the payment in your backend, call the submitOneTimeTokenForm function. The code block below presents how to use the submitOneTimeTokenForm function.

/**
 * This function triggers the same functionality that is called when the customer clicks on the pay form button. This approach does not work if you choosed step for rendering mode.
 */
yuno.submitOneTimeTokenForm()
