Payment not found

Error message

Payment not found

What it means

Thrown when no Payment row matches uid === parsedPayload.metadata.payer_data.referenceId. The reference id embedded in the invoice's payer data does not correspond to any payment recorded by this cal.com instance. Returns HTTP 204 so Svix does not keep retrying.

Solutions

1. Look up the payment table for the given referenceId (uid) to confirm it exists.
2. Ensure invoice creation (prisma.payment.create) is committed before the webhook can arrive, or rely on Svix redelivery.
3. Confirm a single DB instance owns this webhook secret to avoid cross-instance lookups.

const payment = await prisma.payment.findFirst({
  where: { uid: parsedPayload.metadata.payer_data.referenceId },
});
if (!payment) {
  // return 204; rely on Svix redelivery after create commits
}

When it happens

Trigger: Webhook delivered before prisma.payment.create committed; payment belongs to a different DB/instance sharing the secret; referenceId tampered; payment row was deleted.

Common situations: Race between invoice creation and webhook delivery; multi-instance deployment with separate DBs; DB restore where payment rows were lost.
