How it works

Trigger: Schedule — every hour

Every hour, get checkouts abandoned 1–2 hours ago from Shopify.
Keep the ones with a phone number that weren't completed.
Send each customer an approved WhatsApp template with their total and a link back to the cart.

Carts with a phone · Code node

// Keeps abandoned checkouts from the last hour or two that have a phone number
// and were not completed, ready for a WhatsApp reminder.
const checkouts = $input.first().json.checkouts || [];

return checkouts
  .filter((c) => !c.completed_at)
  .map((c) => ({
    phone: String(c.phone || c.shipping_address?.phone || c.billing_address?.phone || "").replace(/[^0-9]/g, ""),
    name: c.shipping_address?.first_name || c.customer?.first_name || "",
    total: `${c.total_price} ${c.currency}`,
    url: c.abandoned_checkout_url,
  }))
  .filter((c) => c.phone.length >= 10)
  .map((c) => ({ json: c }));
