Overlay

Bundlers

import { Invoice } from '@confirmo/overlay';

/**
 * Opens Confirmo invoice overlay
 *
 * @param {string} invoice_url - URL of invoice.
 * @param {callback} [callback_fnc] - Optional - callback which is called when overlay was closed
 * @param {InvoiceOverlayConfig} [overlayConfig] - Optional - Confirmo overlay configuration (currently only for auto-close when invoice is paid)
 *
 * @example
 *
 * // URL of invoice created from REST API
 * const invoice_url = 'https://pay.confirmo.com/public/invoice/invv9e1rxdz8?m=mer951dkwdw1';
 *
 * // (optional) Callback which is called when overlay was closed
 * const callback_fnc = () => alert('Overlay has been closed');
 *
 * // (optional) Confirmo overlay configuration
 * const overlayConfig = {
 *   closeAfterPaid: true,
 *   closeAfterPaidTimeoutMs: 2000, // when unspecified, default is 2000ms
 * }
 *
 */
const overlay = Invoice.open(invoice_url, callback_fnc, overlayConfig);

/**
 * Closes Confirmo invoice overlay

Payment button

import { PaymentButton } from '@confirmo/overlay';

/**

Overlay events

Events fired from Public invoice view via window#postMessage API https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage

A component using @confirmo/overlay can listen to InvoiceOverlayMessageEventData accordingly:

import { ConfirmoOverlayInvoiceStatus, ConfirmoOverlayMessageAction, Invoice } from '@confirmo/overlay';

const overlay = Invoice.open(invoiceUrl, callback_fnc);

// Custom implementation of closing Confirmo overlay after invoice being paid
window.addEventListener('message', (event) => {
  if (
    invoiceUrl.includes(event.origin) &&
    event.data.action === ConfirmoOverlayMessageAction.CONFIRMO_OVERLAY_INVOICE_STATUS_CHANGE &&
    event.data.status === ConfirmoOverlayInvoiceStatus.PAID
  ) {
    // handle paid invoice (e.g. by closing the overlay)
    setTimeout(() => {
      overlay.close();
    }, 2000); // close overlay after 2 seconds
  }
});

Note: the same effect as shown above can be achieved simply by setting overlayConfig's closeAfterPaid

import { Invoice } from '@confirmo/overlay';

const overlayConfig = {
  closeAfterPaid: true,
};

Invoice.open(invoiceUrl, callback_fnc, overlayConfig);
