Attribute revenue with Stripe PaymentIntent API

Before proceeding, confirm that you have linked your Stripe account.

When using Stripe Elements with the PaymentIntent API, include metadata with _fs_vid and _fs_sid (cookies set by Flowsery Analytics) when creating a payment intent on your backend:

// app/api/create-payment-intent/route.js
import { cookies } from 'next/headers';

export async function POST() {
  const cookieStore = cookies();
  // If you're using Next.js 15+, use this instead:
  // const cookieStore = await cookies();

  const paymentIntent = await stripe.paymentIntents.create({
    amount: 2000,
    currency: 'usd',
    metadata: {
      _fs_vid: cookieStore.get('_fs_vid')?.value,
      _fs_sid: cookieStore.get('_fs_sid')?.value
    }
  });

  return new Response(JSON.stringify({ clientSecret: paymentIntent.client_secret }), {
    status: 200,
    headers: { 'Content-Type': 'application/json' }
  });
}

That is all that is needed. Once connected and metadata is passed correctly, Flowsery Analytics will automatically attribute revenue to the appropriate marketing channels via the payment_intent.succeeded webhook. No additional configuration is required.

When to use this method

• Custom checkout flows using Stripe Elements with the Stripe PaymentIntent API
• Mobile apps using Stripe's mobile SDKs

Following a successful payment, revenue data should appear in your dashboard (referrer, country, browser, etc.).
