bitcoind provides a configuration parameter called walletnotify that accepts a script as its parameter. When the wallet receives a transaction for a local address it hits the script configured, passing the txid incoming.

The walletnotify script is hit twice for each transaction; when it first appears on the network (0 confirmations) and after the first confirmation. It is called for both receiving and sending transactions.

walletnotify.php is a self-contained PHP script for processing walletnotify calls. Use as is or customize for your own needs.

• Processes bitcoind walletnotify calls and inserts the transaction into a database (MySQL or SQLite).
• Sends email and SMS notifications on transactions affecting local BTC addresses.
• Provides a simple interface for chaining other processes.

• Receive SMS or email update anytime funds are sent or received.
• Process payments automatically whenever coins are received.
• Automatically sweep coins to cold wallets.
• Automatically pay affiliates / partners pre transaction.
• Micro-Paygate Support Tool
