Too Long; Didn't Read
This article is a practical guide on making a simple Node.js server that will receive BTC transactions as a Webhook and detect if a transaction contains more than $2Bln worth of BTC transfer.

We need a transaction id, transaction inputs, outputs, and their addresses with BTC amount.
