Trying to fetch data and send to affiliate marketing partner

What have you already tried:

Additional information:

Use onOrderPaid() Backend Event

This event is triggered when an order is completed/paid. You can use it to access order details and send them to your affiliate system.

In your backend/events.js file, you can use:
import { wixStoresBackend } from ‘wix-stores-backend’;

export function wixStores_onOrderPaid(order) {
const orderId = order._id;
const orderAmount = order.totals.total;
const shippingCost = order.totals.shipping;
const vat = order.totals.tax;

// Example: Send to affiliate
const dataToSend = {
orderId,
orderAmount,
shippingCost,
vat
};

// Send via fetch, postMessage, webhook, etc.
console.log("Affiliate Payload: ", dataToSend);
}

Common Mistakes to Avoid

  1. Don’t use order.orderId — it’s usually _id (underscore).
  2. order.totals must be present — make sure the order is paid (not just created).
  3. Use console.log(order) inside the event to inspect what you receive live.
