payment.unrecognised

Fires when funds arrive that can’t be matched to an open payment request — wrong asset, wrong chain, or an amount too far off to match. There is no automated resolution; the raw transaction reference is provided so you (or the creator) can investigate manually.

Payload (data)

  "livemode": false,
