Node.js blockchain bitcoin api

Question

So I want to use this: (taken from their API site -> node.js documentation) https://github.com/blockchain/api-v1-client-node

Recieving payments: https://github.com/blockchain/api-v1-client-node/blob/master/docs/Receive.md

var blockchain = require('blockchain.info');
var identifier = 'myidentifier'; 
var password = 'mypassword';
var myWallet = new blockchain.MyWallet(identifier, password);
var myBTCadress = '14Q3ufL1BUHtWskBKtsshVDATRY65TaJMB';

Ok, so the recieving part:

var receive = new blockchain.Receive( [confirmations: 1], ? ); // What do I need to put here?

Documentation says: callbackURL: the url to which the callback should be sent (string)

I don't understand what URL it should go to?!

Answer 1

The callback URL should be the one that redirects back to your site. So setup a callback url with blockchain like...

https://www.yoursite.com/callback/blockchain

Assuming you are using something like express in your app make a route like so.

app.get('/callback/blockchain', function (req, res) {

// Stuff here  

});

you will prob need to include

var https = require('https'); 

That way then you can set up your logic inside for example...

// Stuff here
 var options = {
    host : 'api.blockchain.info',
    path : '/some/path/',
    port : 443,
    method : 'GET'
  }
 var request = https.request(options, function(response){
    var body = ""
    response.on('data', function(data) {
      body += data;
    });
    response.on('end', function() {
      res.send(JSON.parse(body));
    });
  });
  request.on('error', function(e) {
    console.log('Problem with request: ' + e.message);
  });
  request.end();

That will for example output you request in json on whatever page you have your app.get('whateverurl') set to.
