# Paddle chargeback received notifications on your phone

> Get a High-priority push notification when a Paddle payment is charged back, or when an early fraud warning suggests one is coming.

- Company: Paddle (https://www.justpush.io/recipes/paddle)
- Event: `adjustment.created` (adjustment.created)
- Tags: Finance, Payments
- Install: https://studio.justpush.io/recipes/paddle/chargeback-received
- Web page: https://www.justpush.io/recipes/paddle/chargeback-received

## Setup

1. Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
2. In Paddle, go to Developer tools > Notifications and click New destination.
3. Choose Webhook as the type and paste your webhook URL (shown in Studio after install) as the URL.
4. Select the adjustment.created event and save the destination.
5. Refunds, credits and chargebacks all arrive as `adjustment.created`. This recipe only reacts to chargebacks and chargeback warnings, so you can point the refund recipe at the same event without double pushes.
6. The **View transaction** button opens the live Paddle dashboard. Paddle doesn't say in the event whether it came from sandbox or live, so if you're testing in sandbox, change `DASHBOARD` at the top of the code to `https://sandbox-vendors.paddle.com`.
7. Paddle signs each webhook with a `Paddle-Signature` header, but JustPush doesn't verify it yet. Keep your endpoint URL private.

## Code

Studio calls `handleRequest(request)` with the incoming webhook (`{ method, headers, body, query, raw }`) and sends the message object it returns. Returning `null` sends nothing.

```js
// Paddle → chargeback received
// Fires when a customer's bank charges back a payment, or sends an early fraud warning.
// Docs: https://developer.paddle.com/webhooks/overview
//
// Paste this into a JustPush Studio integration and add a Paddle notification destination
// for the "adjustment.created" event pointing at the integration's endpoint URL.

// Paddle amounts are strings in the currency's smallest unit ("4900" = €49.00),
// except for zero-decimal currencies such as JPY, where "500" means ¥500.
const ZERO_DECIMAL = new Set(["jpy", "krw"])

function money(amount, currency) {
    const units = Number(amount)

    // Don't invent a figure when the event doesn't carry one.
    if (amount == null || amount === "" || !Number.isFinite(units) || !currency) return null

    const code = String(currency).toLowerCase()
    const value = ZERO_DECIMAL.has(code) ? units : units / 100

    try {
        return new Intl.NumberFormat("en-GB", { style: "currency", currency: code }).format(value)
    } catch {
        return `${value} ${code.toUpperCase()}`
    }
}

// Paddle events don't say whether they came from sandbox or live, so set this yourself.
// Sandbox: "https://sandbox-vendors.paddle.com"
const DASHBOARD = "https://vendors.paddle.com"

// Chargeback actions, and what to title them.
const CHARGEBACKS = {
    chargeback: "⚖️ Chargeback received",
    chargeback_warning: "🚩 Chargeback warning",
}

function handleRequest(request) {
    const event = request.body

    // Guard: only handle chargebacks, so other Paddle events on this integration stay quiet.
    if (!event?.data || event.event_type !== "adjustment.created") {
        console.log(`Ignoring Paddle event "${event?.event_type ?? "unknown"}"`)
        return null
    }

    // Refunds, credits and chargebacks all arrive as adjustment.created; keep chargebacks
    // and early fraud warnings only.
    if (!Object.prototype.hasOwnProperty.call(CHARGEBACKS, event.data.action)) {
        console.log(`Ignoring "${event.data.action}" adjustment — not a chargeback`)
        return null
    }

    const adjustment = event.data
    const amount = money(adjustment.totals?.total, adjustment.currency_code ?? adjustment.totals?.currency_code)
    const reason = adjustment.reason ? ` — ${adjustment.reason}` : ""
    // A warning comes before the chargeback, while a refund can still head it off.
    const advice = adjustment.action === "chargeback_warning"
        ? ". Consider refunding to avoid a chargeback."
        : ""

    return {
        title: CHARGEBACKS[adjustment.action],
        message: `${amount ?? "A payment"}${reason}${advice}`,
        topic: "Paddle",
        priority: 1, // High — money is (about to be) pulled back, and repeat chargebacks hurt your account
        buttons: adjustment.transaction_id
            ? [{ cta: "View transaction", url: `${DASHBOARD}/transactions-v2/${adjustment.transaction_id}` }]
            : [],
    }
}
```
