How do I use argc/argv?
See above. Basically, argc is the number of arguments on the command line, including the name of the script. argv is an array of the command line elements, starting with argv[0] set to the name of the script. I got it to work with argc and argv. I put the following into bitcoin.conf: walletnotify=/usr/bin/php /path/to/walletnotify.php %sI have the following in walletnotify.php: <?php if(2==$argc){ require_once 'jsonRPCClient.php'; $bitcoin = new jsonRPCClient('http://username:password@127.0.0.1:8332/'); $walletinfo = $bitcoin->getinfo(); $trxinfo = $bitcoin->gettransaction($argv[1]); // Append data to the file $new = "\n\nTransaction hash: ".$argv[1]."\nGetinfo balance: ".$walletinfo["balance"] ."\n Gettransaction amount: ".$trxinfo["amount"] ."\n Gettransaction confirmations: ".$trxinfo["confirmations"] ."\n Gettransaction blockhash: ".$trxinfo["blockhash"] ."\n Gettransaction blockindex: ".$trxinfo["blockindex"] ."\n Gettransaction blocktime: ".$trxinfo["blocktime"] ."\n Gettransaction txid: ".$trxinfo["txid"] ."\n Gettransaction time: ".$trxinfo["time"] ."\n Gettransaction timereceived: ".$trxinfo["timereceived"] ."\n Gettransaction account: ".$trxinfo["details"][0]["account"] ."\n Gettransaction address: ".$trxinfo["details"][0]["address"] ."\n Gettransaction category: ".$trxinfo["details"][0]["category"] ."\n Gettransaction amount: ".$trxinfo["details"][0]["amount"] //."\n Gettransaction fee: ".$trxinfo["details"][0]["fee"] // According to https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_calls_list, fee is returned, but it doesn't seem that way here ; $fp=fopen("/tmp/notify_wallet.txt","a"); fwrite($fp,$new); } ?> When I send testnet coins from my eWallet to my Bitcoin-QT, the above walletnotify.php fetches the transaction's data from the wallet and writes it to the text file. It works well. I didn't need the following code: Thanks for your help!

Sorry to bump this topic but i need to ask something. I tried to test the walletnotify like you and it worked. but my problem is that it notify only after 0 and 1 confirmation then it stops. I need to know if it is possible to set it for a specific number of confirmation because it will help for a callback. I thought that it is possible to use minconf in config but when i add it, i do not even get data logged in the file.

DDOS? zero. There is no amplification, no redirection.
Someone can try to DOS you. But it'll be expensive. Your node will spawn a process for each transaction that hits your wallet, not for each output. You should strive to make the spawned process as light and short lived as possible, but for the most part, there isn't much danger.
For reference, it actually runs the script twice, once when you first hear of it, once when it hits one confirmation (And thus hits the blockchain).

Add TXID to DB after it calls it at one confirmation (To prevent against mutational, tell the user you received it at zero, however), then listen for blocknotify, on blocknotify, grab the TXID info from bitcoind again and update the confirmation. It should always be lastone+1, but, don't assume that, bugs can happen if you do, grab a new copy of the TX from bitcoind and update the confirmation from there.

Lets say I was using a blockchain.info daemon, how would I use walletnotify from them. Would that be possible? I'd prefer not to run a VPS but I might if I have to. My home network and computer wouldn't be trustworthy enough to be used for a public business with hundreds of customers.

If you want to be notified about a transaction in your blockchain.info wallet, just use the http callback. When a transaction comes in, you get a call back every new block until you acknowlegde it.

I have tried blockchain's callbacks before, but they do not work. Sometimes they send duplicates, sometimes they don't even send at all, and they send the wrong information.

Yeah, the http callback is not a really reliable source. You can't count on it for managing a transaction database, and should always have a second system in place to check payments. It is more like a gadget. Duplicates can be send if the acknowlegdment hasn't arrived correctly. Nothing receiving at all can be caused by, well, the same reason why you can't connect to a website some times. Receiving wrong information I haven't experienced using the callback function, so I can't say anything about that. If you want something really reliable, you haven't a lot of options I can think of. It's an http callback from block chain, or a bitcoin deamon at home with wallet notify, or custom made software that acts like a bitcoin node. Maybe there is some other software around that is better suited for these kind of things? What exactly are your requirements?

Wat I did is make a script which automatically sorts get transactions every 15 seconds with a cron job, and it works well. It can handle 10 transactions every 15 seconds, and I can easily make it more.

Then you don't really need a notification, right? Or would you like your costumers to see an instant notification of a transaction?

Would be also interested on other opinions besides bitcoind on using for example btcd, bitcoinj, libbitcoin full node implementations?

On the server I used for testing, in my bitcoin.conf: walletnotify=/home/btcdev/walletnotify.sh %s blocknotify=/home/btcdev/blocknotify.sh %s
The %s in the command line gets replaced with the (ASCII) hex string of the transaction hash, just like -blocknotify replaces it with the block hash. And the program can be as simple or as complicated as you like. Here is a simple shell script: #!/bin/bash F=/home/btcdev/wallet_transaction_log D=`date +"%Y%m%d%H%M%S"` echo ${D} - ${1} >> ${F}
which gives lines like: 20130513123015 - 6fa6c8ff08f122327b7a0a329d7632f243038f0fc96cce1248cb4948d0509ecf
You aren't limited to shell scripts, of course. A pipe would have been better, but they aren't portable. Even if we had been willing to limit it to just UNIX-ish systems, there would have been horrible locking problems, and these notices simply weren't worth the effort to work around them*. If you want similar behavior, you can fake a pipe with netcat, so that you could have a long running service that accepts TCP connections from localhost, and just call netcat to dump the txid to that socket. * Did you know that named pipes can stall in both directions, potentially DOSing one of the client threads? There are ways around it, of course, but you have to throw out a lot of the abstractions, so there would have been a very un-C++ chunk of code in the bitcoin client, just for dealing with the pipes. At least that was how it looked to me when I was researching it. I don't do much with C++, so I'm hoping that someone in the audience is more skilled than I am, and will read this and say "You dumbass, why didn't you just do X?", or even better, rewrite it for me. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Hey, anybody else has issue in bitcoind with walletnotify that on first confirmation it shoots the curl twice immidiately and when checking the wallet_transaction_log file, there is also same txid written twice. so the issue is not in my built API server, but in bitcoind. any clues?

Is walletnotify limited to one occurrence in bitcoin.conf, or can it be used multiple times? Which one below would be better to use, or something different? walletnotify=cmd-A walletnotify=cmd-B
or walletnotify=cmd-A && cmd-B
I'm guessing the second is better, if the first is even possible. While I am asking, how about alertnotify and blocknotify? ![Huh](https://bitcointalk.org/Smileys/default/huh.gif)

Walletnotify notifies you twice in a deposit. 1- Once someone deposited into an address (0 conf). 2- When that transaction gets 1 confirmation. And it also notifies you if you "withdraw" one address.

Sorry for the (very) late reply, but I still don't see how that brings me closer to why I get an error code? Thanks.
