Request a Blockchain API V2 to receive Payments


Request a Blockchain API V2 to receive Payments

this will help I don't know why exactly, but they have become extremely strict as to who they give API keys now. Previously it was very easy, and now they heavily investigate the intended usage. I wouldn't be surprised if the reason has to do with gambling sites and scams that were using their API.
As for recommendations you can run your own node on a VPS or use another 3rd party API. The only one that is as easy to use as blockchain.info, but actually gives out API keys is block.io. The catch is the free version is severely limited. There's also blocktrail, and blockcypher.

I wish did fix the issue. Problem solved. I talked to Blockchain staff. Apparently my test transfers were to small. YOU NEED TO TRANSFER AT LEAST 0.001BTC.
In the future I recommend blockchain.info's wallet API, instead of its receive payments API.
How do I use Blockchain.info's Receive Payments API with node JS / Express?

I think the issue was by ths following , They have great documentation for PHP, but nothing really for node! , To create the address you can use something like this:
app.js:
code :
api = require('blockchain')
app.post('/api/blockchain/createAddress', api.blockchainCreateAddress);
exports.blockchainCreateAddress = function(req, res) {

    var btc_address = '<you-destination-btc-address>';
    var api_url = 'https://blockchain.info/api/receive';
    var callback_url = '<your-callback-url>';

    var url = api_url + '?method=create&address=' + btc_address + '&callback=' + encodeURIComponent(callback_url);

    if (btc_address)
    {
        https.get(url, function(resp) {

            console.log("Calling Blockchain API at " + url)

            var body = '';

            resp.on('data', function(chunk) {
                body += chunk;
            });

            resp.on('end', function() {
                try
                {
                    console.log('Blockchain returns: ' + body);

                    res.json(JSON.parse(body));
                }
                catch(e)
                {
                    msg.error = e;
                }           

            });
        }).on('error', function(e) {
            msg.error = e;
        });
    }
};
[...]
app.get('<your-callback-path>/:value/:input_address/:confirmations/:transaction_hash/:input_transaction_hash/:destination_address', api.blockchainCallback);
[...]
exports.blockchainCallback = function(req, res) {
   // Go on and save/store the payment
   // remember to send *ok* result string when you are done
   res.send("*ok*");
});

should help you out I think I can help. Disclaimer that I work for BlockTrail.
It would not be good to use the same address because people can view the historical transactions associated with that address. It is recommended to use a new address for every transaction. These can be under the same wallet or different wallets. That may sound complicated but with the possibilities as long as the universe is old you can make a new address per transactions. Some wallets will do this for you automatically. This is called HD Wallets or Hierarchical Deterministic Wallets. You can also use this to have your clients always pay into the same wallet.

I hope this helps you . According to their documentation there will always be the parameters 'value', 'transaction_hash', 'input_address' and 'confirmations' as well as any constants you specify as parameters in the URL already. The 'value' parameter appears to be what you expected as price.
You cannot give the parameters custom names though.
