Attribute revenue with Stripe PaymentIntent API

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

Flowsery processes these Stripe webhook events:

checkout.session.completed
invoice.payment_succeeded
charge.refunded

Routing to the correct website is automatic (Flowsery registers a dedicated webhook URL per site) — you don't need to pass websiteId. To attribute the payment to the visitor's traffic source, forward the Flowsery cookies (_fs_vid / _fs_sid) as metadata when you create the PaymentIntent:

JavaScript

const paymentIntent = await stripe.paymentIntents.create({
  amount: 2000,
  currency: 'usd',
  metadata: {
    fs_visitor_id: req.cookies['_fs_vid'],
    fs_session_id: req.cookies['_fs_sid'],
  },
});

If you can't set metadata, call identify(email) so Flowsery can match the payment by email.
