Bitcoin Wallet Transaction Callback

Question

Is it possible for the Bitcoin client (running in server mode) to send a HTTP request upon receiving a transaction and it being confirmed? Ie to send to a PHP script for callback/confirmation.

Answer 1

This is possible using the walletnotify parameter in your bitcoin.conf file.

walletnotify=/home/bitcoin/transaction.sh %s

This will call the transaction.sh script with the txid as a paramter. From there you can basically do anything.

For example:

#!/bin/sh
curl -d "txid=$1" http://127.0.0.1/callback

Note: the address you want to monitor has to be part of your wallet
