How to embed a Popup Checkout Page on a Next.js application (React)

alexco888 · Nov 28, 2023

Hi!
I hope you are great!

I just found this information about how to embed a Checkout Page with traditional HTML: https://forum.pabbly.com/threads/em...ur-website-button-a-step-by-step-guide.12097/
Can somebody in here help me understand how to do that in my Next.js application? I am using Next.js 14 (using App router).
Right now I have this code in my layout.tsx:

JavaScript:

/* eslint-disable @next/next/inline-script-id */
import type { Metadata } from 'next';
import { Inter } from 'next/font/google';
import './globals.css';
import Script from 'next/script';

const inter = Inter({ subsets: ['latin'] });

export const metadata: Metadata = {
  title: '',
  description:'',
};

export default function RootLayout({
  children,
}: {
  children: React.ReactNode;
}) {
  return (
    <html lang='en'>
      <body className={inter.className}>
        {children}
        <Script src='https://payments.pabbly.com/api/checkout/popup-checkout.js' />
      </body>
    </html>
  );
}

Nevertheless in my Pricing.tsx component (where I want to have a button that opens the popup checkout page) I receive an error: open_center_popup is not defined when I try to follow the instructions of the provided URL.
Thank you very much for your support!

The provided information did not work since I am working with Next.js and not traditional HTML (like Wordpress).
Nevertheless, I found how to implement Pabbly Embedded Popup Checkout Pages. I share my solution in case this help to somebody else in the forum

.
I am using Next.js 14 with Typescript.

In my layout.tsx in my App directory:

JavaScript:

/* eslint-disable @next/next/inline-script-id */
import type { Metadata } from 'next';
import { Inter } from 'next/font/google';
import './globals.css';
import Script from 'next/script';

const inter = Inter({ subsets: ['latin'] });

export const metadata: Metadata = {
  title: '',
  description:'',
};

export default function RootLayout({
  children,
}: {
  children: React.ReactNode;
}) {
  return (
    <html lang='en'>
      <body className={inter.className}>
        {children}
        <Script
          id='pabbly-script'
          src='https://payments.pabbly.com/api/checkout/popup-checkout.js'
        ></Script>
      </body>
    </html>
  );
}

In my component pricing.tsx (where the button is inserted):

JavaScript:

 const [isScriptLoaded, setIsScriptLoaded] = useState(false);

  useEffect(() => {
    const checkScriptLoaded = () => {
      const script = document.getElementById('pabbly-script');
      if (script && (window as any).open_center_popup) {
        setIsScriptLoaded(true);
      } else {
        setTimeout(checkScriptLoaded, 500);
      }
    };

    checkScriptLoaded();
  }, []);

  const handleButtonClick = () => {
    if (isScriptLoaded) {
      window.open_center_popup(
        'https://payments.pabbly.com/subscribe/xxxxxxxxxxxxxxxxxxx/name-of-your-product?is_popup_preview=true'
      );
    } else {
      console.log('Pabbly script not loaded yet');
    }
  };

Then inside this same component (pricing.tsx) my button calls handleButtonClick when it is clicked:

JavaScript:

 <a
                  // href={tier.href}
                  onClick={handleButtonClick}
                  aria-describedby={tier.id}
                  className={classNames(
                    tier.featured
                      ? 'bg-white/10 text-white hover:bg-white/20 focus-visible:outline-white'
                      : 'bg-indigo-600 text-white shadow-sm hover:bg-indigo-500 focus-visible:outline-indigo-600 mt-6',
                    'block rounded-md py-2 px-3 text-center text-sm font-semibold leading-6 focus-visible:outline focus-visible:outline-2 focus-visible:outline-offset-2 cursor-pointer'
                  )}
                >

I hope this might help other people with the same situation using Next.js with React.

By the way, I forgot to mention that I needed to create as well in the app directory a new file: global.d.ts with the following code (due to Typescript):

JavaScript:

// global.d.ts
export {};

declare global {
  interface Window {
    open_center_popup: (url: string) => void;
  }
}
