Is Using the Stripe Checkout Session ID in the URL a Safe and Effective Method for Google Ads Conversion Tracking in React?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I need to set up conversion tracking for Google Ads using Stripe Checkout. My plan is to detect the session_id query parameter in the URL, remove it, and send a purchase event.

On a successful transaction, the webpage redirects to a URL like this:

JAVASCRIPT
success_url: `${FRONTEND_URL}/app/somepath/${someVariable.id}?session_id={CHECKOUT_SESSION_ID}&screen=some_screen`,

Stripe will automatically replace {CHECKOUT_SESSION_ID} with the actual checkout session ID.

In my React app, I listen for changes in the search parameters and trigger a purchase event when session_id is detected:

JAVASCRIPT
import { useEffect } from 'react';
import { useSearchParams } from 'react-router-dom';

function StripeConversionTracker() {
  const [searchParams, setSearchParams] = useSearchParams();

  useEffect(() => {
    const sessionId = searchParams.get('session_id');

    if (sessionId) {
      // Remove the session_id parameter from URL
      const newSearchParams = new URLSearchParams(searchParams);
      newSearchParams.delete('session_id');
      setSearchParams(newSearchParams, { replace: true });

      // Send conversion event
      if (window.gtag) {
        gtag('event', 'purchase', {
          transaction_id: sessionId,
          // Add any additional parameters needed for your conversion tracking
          send_to: 'AW-CONVERSION_ID/CONVERSION_LABEL'  // Replace with your actual values
        });
      }

      // You can also track with other analytics services here
      // For example, with Facebook Pixel:
      if (window.fbq) {
        fbq('track', 'Purchase', {
          content_ids: [sessionId]
        });
      }
    }
  }, [searchParams, setSearchParams]);

  return null;
}

export default StripeConversionTracker;

Is this approach safe and reasonable for conversion tracking using Stripe Checkout, or are there better alternatives?

Below is an analysis of your approach and some points to consider:

Is It Safe?

Exposure of session_id:
The session_id you’re using isn’t a secret value—it’s essentially an identifier for your checkout session. Using it for conversion tracking is generally acceptable because it isn’t exposing sensitive payment information.
Client-Side Triggering:
While initiating the conversion event from the front end is common, make sure that you’re not solely relying on client-side logic. This is because things like ad blockers, script errors, or users leaving the site before the event fires can cause missed conversions.
Data Verification:
Although it’s safe to use the session_id in this context, consider verifying that the checkout session completed successfully on your backend (using Stripe’s API to retrieve the session) before you attribute conversions. This step can help avoid potential discrepancies due to early or accidental redirections.

Is It a Reasonable Way?

The approach you described is a common pattern for web applications that combine Stripe Checkout with third-party tracking (like Google Ads):

Using URL Parameters:
Stripe’s automatic replacement of {CHECKOUT_SESSION_ID} ensures that you pass along a valid reference. Listening for the presence of the session_id and then removing it to clean up the URL is a sound practice for avoiding duplicate events.
Tracking with gtag and fbq:
Sending the purchase event using gtag for Google Ads (and fbq for Facebook Pixel, if needed) directly on the client side is a standard method. Just ensure you maintain consistency and, if needed, implement additional verification logic.
State Management within React:
Your useEffect hook that watches for changes in the search parameters and then sends conversion events is a reasonable implementation in a React app. The removal of the session_id from the URL helps avoid re-triggering the event if the user navigates or refreshes the page.

Additional Considerations

Backend Confirmation:
For enhanced reliability, you might consider a server-side process to verify the checkout session status via Stripe’s API before you mark a conversion. This can be especially useful if accuracy is critical and you want to confirm the payment is indeed successful.
Handling Failures:
Ensure you have some error handling for cases where the conversion event might fail to fire (due to network issues, ad blockers, etc.) so you can possibly resend or log these events for later reconciliation.

Conclusion

Yes, your approach is safe and a reasonable way of doing conversion tracking with Stripe Checkout. Just be mindful of potential pitfalls on the client side and consider adding backend verification if you need additional accuracy or fraud mitigation.

Feel free to ask if you need further clarification on any part of the integration!

There actually is a plug-and-play solution for this: https://www.tracklution.com/stripe-conversion-tracking/

You basically have to do only few steps:

Implement tracking script to your website () (with DNS setting you can make it 1st-party) --> Traclution saves and stores GCLIDs for you
Redirect users back to your website from Stripe: example.com/thank-you/?stripe_session_id={CHECKOUT_SESSION_ID} (configured in Stripe)
Set up webhook in Stripe that triggers on checkout.session.completed event and delivers Purchase data back to Tracklution
Connect Google Ads API with your Tracklution account (few clicks in Tracklution dashboard)

--> Tracklution will tie together the website session with GCLID and Purchase data from Stripe, and send the Purchases back to Google Ads

More documentation/detailed instructions: https://docs.tracklution.com/installation/stripe-integration

With it you can use also other platforms, like send data to GA4 or Facebook Conversion API.
