Attribute revenue with Stripe Checkout API
Make sure you've connected your Stripe account first.
Pass metadata with datafast_visitor_id and datafast_session_id (cookies from DataFast) when creating a checkout session:
// app/api/create-checkout/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 session = await stripe.checkout.sessions.create({
line_items: [...],
mode: 'payment',
metadata: {
datafast_visitor_id: cookieStore.get('datafast_visitor_id')?.value,
datafast_session_id: cookieStore.get('datafast_session_id')?.value
}
});
return new Response(JSON.stringify({ sessionId: session.id }), {
status: 200,
headers: { 'Content-Type': 'application/json' }
});
}
Once connected and metadata is properly passed, DataFast will automatically attribute revenue to the correct marketing channels. No webhook setup is required.
After receiving a successful payment, you should see revenue data in your dashboard (referrer, country, browser, etc.). If you don't, please contact us at marc@datafa.st.
