Receive webhook events

MONEI notifies your server when something happens to a payment, refund, or subscription — so you can fulfill orders, update your database, or send receipts without polling. There are two ways to receive these notifications.

Account webhooks

Account webhooks send every event you subscribe to, across all your activity. Configure them in Dashboard → Settings → Webhooks:

1. Add a webhook endpoint URL — an https:// URL on your server.
2. Select the event types you want to receive.
3. Enable it.

You can add more than one endpoint — for example, one for payments and another for subscriptions. Each endpoint is listed with the events it receives and whether it is enabled. Click an endpoint to see every event MONEI sent to it — see Monitor deliveries.

Webhooks page in the MONEI Dashboard settings, listing the endpoints MONEI notifies

Each delivery is a JSON event envelope:

{
  "id": "d0c3e5b8a7f24c1e9b6a2f0e8d7c4b3a",
  "type": "charge.succeeded",
  "object": {"id": "...", "status": "SUCCEEDED"}
}

Read type to know what happened, and object for the affected resource (a payment, refund, or subscription).

Payment callback (callbackUrl)

When you create a payment, you can set a callbackUrl. MONEI then sends the Payment object directly (not an envelope) to that URL — even if the customer closes their browser during the redirect. It sends it once, when the payment first succeeds, fails, is authorized, is canceled, or is paid out. It doesn't send it when a payment expires, and an authorized payment that you capture later doesn't get a second callback: use account webhooks to follow later changes. Use this when you only care about a specific payment's result.

See Verify signature for ready-to-use Node, PHP, and Python examples that handle the callback.

Event types

A charge is a payment, so charge.* events track the payment lifecycle.

Group	Events
Payments (charges)	charge.succeeded, charge.failed, charge.pending, charge.pending_processing, charge.authorized, charge.captured, charge.canceled, charge.expired, charge.refunded, charge.partially_refunded, charge.paid_out, charge.chargeback, charge.updated
Chargebacks	chargeback.created, chargeback.escalated, chargeback.representment_submitted, chargeback.under_review, chargeback.won, chargeback.lost, chargeback.expired, chargeback.closed, chargeback.updated
Payouts (settlement)	settlement.completed, settlement.pending, settlement.suspended
Subscriptions	subscription.activated, subscription.updated, subscription.canceled, subscription.paused, subscription.past_due, subscription.trialing, subscription.pending, subscription.expired
MONEI invoices	account_invoice.paid, account_invoice.pending, account_invoice.unpaid, account_invoice.past_due

A refund has no event of its own: the payment it belongs to reports charge.refunded, or charge.partially_refunded when part of the amount is left.

WebhookEventType describes what each event means.

Delivery order and duplicates

MONEI delivers each event at least once, and in no guaranteed order. Two states that change moments apart can arrive the wrong way around, and a retry or a resend can deliver an event your server already has. Both are rare, and your handler still has to survive them:

• Make your handler idempotent. Ignore an event whose id you have already processed.
• Trust the payment, not the arrival order. Read status in the payload, and ignore an event that describes a state you have already moved past. When you need certainty, retrieve the payment.
• Subscribe to final states such as charge.succeeded and charge.failed. The fewer intermediate events you take, the fewer near-simultaneous changes you have to order.
• Reject what you can't process yet. Answering with a status other than 2xx tells MONEI the delivery failed, so the event comes back on the retry schedule — until those attempts run out.

For a single payment's outcome, a payment callback is the more direct route: MONEI posts the Payment object to the callbackUrl of that payment alone, so there is nothing to order.

Retries

MONEI waits up to 60 seconds for your server to answer. It doesn't follow redirects, so a 3xx answer counts as a failure.

If your server doesn't answer with a 2xx status such as 200 OK, MONEI tries again, waiting longer after each failure. An account webhook gets 18 attempts spread over about three days — seconds apart at first, then minutes, then hours, with the last few 11 hours apart. A brief outage on your side costs you nothing, and a longer one still leaves you almost three days to fix it. In test mode there are only 3 attempts, seconds apart, so a broken test endpoint shows as failed within a few minutes.

They are not endless. After the last attempt the event is given up on, and events are never queued for later delivery. You can still resend it yourself for 30 days.

An endpoint is disabled only after seven days of failing with no success in between. A single successful delivery at any point resets that clock, so one bad endpoint doesn't switch off on a transient problem. When it does get disabled, MONEI emails your account admins and nothing reaches it until you turn it back on in Dashboard → Settings → Webhooks.

A payment callback has its own schedule: about 30 attempts, one hour apart, over about 29 hours. Callbacks aren't in the delivery log and you can't resend them. MONEI signs a callback once, so every retry carries the same timestamp in the MONEI-Signature header. If you reject old timestamps, allow for a retry that arrives hours after the first attempt.

So don't treat delivery as guaranteed. Reconcile anything you might have missed by retrieving the payment rather than waiting for a webhook that may never arrive.

Monitor deliveries

Click an endpoint in Dashboard → Settings → Webhooks to open its page:

• Endpoint — the URL, the event types and whether the endpoint is enabled, with Edit and Delete.
• Last 30 days — how many deliveries MONEI made each day and how many failed, and how fast your server answered, on average and at its slowest.
• Event deliveries — every event MONEI sent to this endpoint, newest first. Filter it by status, or search for an event ID.

Webhook endpoint page in the MONEI Dashboard, with the endpoint details, delivery and response-time charts for the last 30 days, and the log of event deliveries

Test mode and live mode have separate endpoints, so the page shows only the deliveries of the mode you are in. The log covers account webhooks only, not the per-payment callbackUrl.

Delivery statuses

MONEI keeps one delivery for each event and endpoint, and updates it after each attempt. Attempts in the log counts them.

Status	Meaning
Delivered	Your server answered with a 2xx status.
Pending	MONEI has not sent it yet.
Retrying	At least one attempt failed, and MONEI will try again.
Failed	Every attempt failed, or MONEI couldn't send it (for example, the endpoint was disabled). MONEI does not try again, but you can resend it.

Inspect a delivery

Click a delivery to open its details: the response code your server returned, how long it took, when MONEI last tried and when it tries next. Below them are the Response body your server sent back and the Request MONEI sent, which is the exact event payload. When a delivery fails, the response body usually holds the error your handler raised.

Delivery details dialog in the MONEI Dashboard, for a delivery that is being retried: the response code and body your server returned, the next retry, and the request MONEI sent

MONEI keeps deliveries for 30 days, and the charts cover the same period.

Resend a delivery

After you fix your handler, click Resend in the delivery details to send the event again. MONEI sends the same payload with the same event id, and signs it again with a new timestamp in the MONEI-Signature header.

The resend is a new delivery in the log, with its own retries. It does not stop the retries of the original delivery, so your server can receive the same event twice. Ignore duplicates by the event id, never by the signature, which changes on every attempt.

Resend is not available when:

• the endpoint is disabled — enable it first;
• the event was too large for MONEI to store in full.

Deliveries in the API

The same data is in the GraphQL API. List deliveries with webhookDeliveries, read one with its request and response bodies with webhookDelivery, get the daily figures behind the charts with webhookDeliveryStats, and resend with resendWebhookDelivery. A resent delivery has source: MANUAL.

Verify every request

Every webhook and callback includes a MONEI-Signature header — an -SHA256 signature computed with your API key. Always verify the signature before trusting the payload, then respond with a 200 status to acknowledge receipt.
