Bitcoin wallet transaction callback

Question

Is it possible that the Bitcoin client (working in server mode) will send an HTTP request after receiving the transaction and be confirmed? That is, to send to a PHP script for a 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 transaction.sh script with txid as a parameter. From there, you can basically do something.

For instance:

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

Note: The address you want to control must be part of your wallet.
