Webhooks
Note
This functionality is exclusively accessible with paid subscriptions. Verify whether your plan includes this feature, upgrade if necessary, or reach out to us for assistance.
When incorporating Oveit integrations, you may want your applications to promptly
receive events as they transpire in your Oveit accounts. This allows your backend
systems to execute corresponding actions.
To activate webhook events, the process involves registering webhook endpoints. Once
registered, Oveit can push real-time event data to the designated webhook endpoint of
your application whenever events occur in your Oveit account. Oveit utilizes HTTPS to
transmit webhook events to your app, delivering them in the form of a JSON payload
that encompasses an event object.
Receiving webhook events proves particularly beneficial for monitoring asynchronous
occurrences, such as when an order is placed, an attendee completes a registration form,
or an invoice is issued.
Event Overview
Oveit produces event data that we can transmit to keep you informed of activities within
your account. Each time an event takes place, Oveit generates a new event object
(see below).
By enlisting webhook endpoints in your Oveit account, you empower Oveit to
autonomously dispatch event objects via POST requests to the designated webhook
endpoint hosted by your application. Once your webhook endpoint receives the event,
your application can execute backend actions, such as invoking your CRM APIs to store
customer information upon receiving an "order.create" event.
| Event | Trigger | Event object |
|---|---|---|
| order.place | When an order is placed and awaits payment confirmation (bank transfer, house account) | order (see below) |
| order.create | When an order is completed (paid, tickets issued) | order (see below) |
| order.cancel | When an order is canceled (manually by an operator or after a failed or canceled payment) | order (see below) |
| ticket.create | When a ticket is issued | ticket (see below) |
| ticket.update | When a registration form is changed | ticket (see below) |
| pms.reservation.update | When Oveit syncs a reservation from a connected PMS ( create or update ) | reservation (varies by PMS) |
| payment.create | When a payment on a house account order is confirmed (bank transfer or check recorded, Shift4 card or payment link charge confirmed) | payment, order (see below) |
| payment.cancel | When a recorded bank transfer or check on a house account order is voided | payment, order (see below) |
| payment.refund | When a payment is refunded, in full or in part (see scope) | payment, refund, order (see below) |
Payment events are new and opt-in: existing webhooks only receive them once you select them on the webhook. To read recent payments in the same shape without waiting for an event, use List payments.
Let's get started
Log in to your account and navigate to the Webhooks section within the Apps panel. From there, you can create a new webhook by entering your webhook callback URL and choosing the events you wish to monitor.
Ensure the Security of Your Webhooks
Once you've confirmed that your webhook endpoint connection functions as expected,
enhance the security of the connection by implementing best practices outlined in the
section below.
One crucial best practice involves using webhook signatures to validate that Oveit
generated the webhook request and that it didn't originate from a server posing as
Oveit.
Event Delivery Behaviors
Retry Behavior
Oveit makes attempts to deliver a specific event to your webhook endpoint for up to 2
days at intervals of 1 minute, 10 minutes, 30 minutes, 1 hour, 2 hours, 6 hours, 12 hours,
18 hours, 24 hours, 36 hours, 48 hours, or until the endpoint responds with a 200 HTTP
status code.
Disable Behavior
Oveit endeavors to notify you of a misconfigured endpoint via email if the endpoint
hasn't responded with a 200 HTTP status code for multiple consecutive days and also
it will be automatically disabled.
Best Practices for Using Webhooks
Handle Duplicate Events
Webhook endpoints may occasionally receive the same event more than once. One
approach is to log the events you've processed and avoid processing events that have
already been logged. Every event has an unique uuid identifier.
Only Listen to Event Types Your Integration Requires
Configure your webhook endpoints to receive only the necessary event types for your
integration. Listening to extra events (or all events) can strain your server unnecessarily,
and it is not recommended.
Receive Events with an HTTPS Server
If you use an HTTPS URL for your webhook endpoint, Oveit validates that the connection
to your server is secure before transmitting your webhook data. Your server must be
properly configured to support HTTPS with a valid server certificate for this to work.
Verify Events Are Sent from Oveit
Authenticate the origin of received events from Oveit by confirming webhook signatures. Oveit secures webhook events sent to your endpoints by appending two headers to each event: a signature header named Oveit-WH-Signature and a timestamp header named Oveit-WH-Signature-Timestamp. This setup enables you to validate the authenticity of the events, ensuring they are genuinely dispatched by Oveit and not manipulated by a third party.
To verify, generate an HMAC (Hash-based Message Authentication Code) signature. This process involves hashing a combination of the payload and timestamp using the webhook secret key from the Dashboard. As the timestamp is a crucial element of the signed payload, any tampering by an attacker would invalidate the signature. If the signature is correct but the timestamp is excessively outdated, your application retains the option to reject the payload. Consider allowing a tolerance of 5 to 10 minutes between the timestamp and the current time.
Retrieve Your Endpoint's Secret
Navigate to the Webhooks section of the Dashboard. Choose the specific endpoint for
which you want to acquire the secret and locate the secret.
Oveit generates a distinctive secret key for each endpoint. In case you utilize multiple
endpoints, you need to procure a secret for each one that requires signature
verification. Oveit then begins signing each webhook it dispatches to the respective
endpoint.

Tickets on order.place
On order.place, tickets are not issued yet. The tickets array lists the tickets the order will issue
once payment is confirmed (one entry per ticket), with the same properties as on order.create, so
registration forms are always read from tickets[].registration_form. Properties that only exist once
a ticket is issued are empty: id, code and series are null, and download_link is empty.
When the order is completed, order.create sends the issued tickets in the same order.

Tickets on order.cancel
On order.cancel, status is canceled, is_canceled is true and cancellation_date holds the
moment the order was canceled. Every ticket has cancelled: true and an empty download_link.
- If the order was completed,
ticketslists the issued tickets, as onorder.create. - If the order was canceled while awaiting payment, no ticket was issued and
ticketslists the same entries as onorder.place. Seats.io seats are released on cancellation, so theirseatisnull.
Each issued ticket of the canceled order is also sent as a ticket.update event.
Payment Data Object
payment.create, payment.cancel and payment.refund send the payment, its order and, on
payment.refund only, the refund that was just made. The payment is always in its current state, so
an event that arrives out of order can be handled by looking at payment.status.

Payment properties
| Property | Description |
|---|---|
id |
Payment id. It is unique only within its source: identify a payment by source and id together. |
source |
house_account for payments collected on a house account order, online for orders paid at checkout. |
processor |
shift4, or null for bank transfers and checks, which are not collected through a processor. |
method |
bank_transfer, check, shift4_card or shift4_payment_link on house account orders; card on online orders. |
status |
successful, canceled (a voided bank transfer or check), refunded or partially_refunded. |
amount |
Amount paid, as a string with two decimals. |
refunded_amount |
Total refunded so far on this payment. 0.00 when nothing was refunded. |
currency |
ISO 4217 currency code. |
reference |
Bank transfer or check reference entered by the operator, or the Shift4 charge id. Can be null. |
created_at, updated_at |
ISO 8601 dates, in the same timezone as the order date (the event timezone, or the organizer timezone for orders without a single event). |
New values may be added to source, processor and method as more payment processors are covered,
so do not reject values you do not recognize.
Refund properties
refund is present only on payment.refund and describes the refund that triggered the event.
| Property | Description |
|---|---|
amount, currency |
What went back to the customer in this refund. |
type |
full when the payment has nothing left to refund (its status is refunded), partial otherwise (its status is partially_refunded). |
notes |
The reason entered when refunding an online order. null on house account refunds. |
credit_note_id |
Id of the credit note issued for an online refund. null on house account refunds, which do not issue one. |
refunded_at |
ISO 8601 date of the refund, in the same timezone as the payment dates. |
Order on payment events
order has the same properties as on the other order events. House account orders are usually still
awaiting payment when their payments change, so tickets lists the tickets the order will issue, as on
order.place (see above).
When a payment completes an order, order.create is sent as well. If canceling an order refunds a
payment covered below, both order.cancel and payment.refund are sent.
Payment events scope
payment.createandpayment.cancelcover house account orders only. Online orders keep usingorder.create(money in) andorder.cancel(money out).- On house account orders,
payment.createis sent when an operator records a bank transfer or check, and when a Shift4 card or payment link charge is confirmed (once, even if the confirmation reaches us twice).payment.cancelis sent when an operator voids a recorded bank transfer or check. - House account
payment.refundis sent when a confirmed Shift4 card or payment link payment is refunded. These refunds are always full. - Online
payment.refundcovers Shift4 only: it is sent when an invoice of an order paid through Shift4 is refunded in full or in part from the order page.
No payment event is sent for:
- Retail Cloud (Box Office POS) tenders.
- Failed, abandoned or pending payment attempts.
- Other payment processors (JCC, Callpay, Crypto.com, Stripe, PayPal and others), including the refunds they make when an order is canceled or an invoice is reversed.
- Refunds made directly in the Shift4 dashboard.
