  • Save Card for future payments
  • Render mode
  • Text payment form buttons
  • Persist credit card form to retry payments
  • Hide Pay button

Form loader

Control the use of the loader.

yuno.startCheckout({
  showLoading: true,
})

Form of the issuer

yuno.startCheckout({
  issuersFormEnable: true,
})

Mode of form rendering

yuno.startCheckout({
  renderMode: {
    /**
     * Type can be one of `modal` or `element`
     * By default the system uses 'modal'
     * It is optional
     */
    type: 'modal',
    /**
     * Element where the form will be rendered.
     * It is optional
     * Can be a string (deprecated) or an object with the following structure:
     * {
     *   apmForm: "#form-element",
     *   actionForm: "#action-form-element"
     * }
     */
    elementSelector: {
      apmForm: "#form-element",
      actionForm: "#action-form-element"
    } 
  },
})

Card form configurations

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

Save card for future payments

In addition, you can display a checkbox for saving or enrolling cards using the cardSaveEnable: true. Below are examples of the checkbox for both card form renders.

Rendering modes

Below you find screenshots presenting the difference between the following:

• Render modes modal and elements for the payment method list.
• Render modes step and extends for the credit card form.

You also can choose one of the render options for the card form, step and extends:

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 form. 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 doesn't work on the step Card form
 */
yuno.submitOneTimeTokenForm()

Mercado Pago Checkout Pro webview handling

❗️

Special Exception

This section describes a special exception for handling Mercado Pago Checkout Pro integration in webview environments. This is the only payment method that requires custom redirect handling, and it is documented here to avoid overwhelming merchants with unnecessary implementation details for other payment methods.

For Mercado Pago Checkout Pro integration in webview environments, the await yuno.continuePayment() method will return either an object with redirect information or null. When the method returns an object, it allows you to handle the custom redirect flow required by Mercado Pago Checkout Pro. When it returns null, no additional merchant-side action is needed.

{
  action: 'REDIRECT_URL'
  type: 'MERCADO_PAGO_CHECKOUT_PRO'  // Enum value identifying Mercado Pago Checkout Pro
  redirect: {
    init_url: string    // URL to redirect to for completing the payment
    success_url: string // URL to redirect to after successful payment
    error_url: string   // URL to redirect to after failed payment
  }
} | null
