Offer Closed Webhook Event

Straumur Team

A new Offer Closed webhook event is now available. This event fires when a payment offer expires — for example, because the shopper abandoned the session. For cards, offers expire after 12 hours by default. It lets your system reconcile the offer against your own records.

What's included​

The OfferClosed event uses the standard payment webhook envelope and provides:

  • The checkoutReference, payfacReference, and merchantReference identifying the transaction
  • The amount and currency of the offer
  • The success outcome of the event (reason is only populated when success is false)

HMAC signature​

The HMAC signature for OfferClosed is calculated over the standard payment signing path: CheckoutReference, PayfacReference, MerchantReference, Amount, Currency, Reason, Success.
