invoice.expired

Fired when an invoice’s expiresAt timestamp is reached and the invoice has not been fully paid.

Manually cancelling an invoice via POST /api/v1/invoices/:id/cancel flips its status to expired but does not fire this webhook. If you cancel an invoice from your backend, you already know it’s gone — handle the cancellation flow synchronously.

When it fires

The invoice expiresAt timestamp is reached and the cumulative received amount is less than the invoice total. data.expiry_reason distinguishes two cases:

`data.expiry_reason`	Meaning
`no_payment`	No payment was received. Customer abandoned the checkout.
`underpaid_unresolved`	A partial payment was received but the customer did not complete it before expiry. The partial funds remain at the deposit address — contact Settlx support to recover them.

What to do

Mark the order as failed and release any reserved inventory. If data.expiry_reason === 'underpaid_unresolved', you may want to contact the customer — they likely intended to pay and may try again. Issue a new invoice for the same amount (or the shortfall) and send them the new paymentUrl.

Handler example

Node.js

case 'invoice.expired': {
  const { invoice, expiry_reason } = event.data;
  const orderId = invoice.metadata?.orderId;

  await db.orders.update({
    where: { id: orderId },
    data: { paymentStatus: 'expired', expiryReason: expiry_reason },
  });

  await inventory.release(orderId);

  if (expiry_reason === 'underpaid_unresolved') {
    // Customer paid partial — they may want to retry. Send a recovery email.
    await emailService.sendRecoveryEmail(orderId);
  }

  break;
}

invoice.settled — The happy path — full payment received and settled.
invoice.underpaid — Fired earlier when partial payment was received before expiry.
