Trustly Client

Node.js client for trusty integrations. Right now it doesn´t includes the withdrawal, feel free to submit a pull request. You can use callback style or promises.

##Getting started

Install the module with: npm install trustly-client

    var client = require('trustly-client');
    var tClientKP = client(configuration);
    //Promise style
    tClientKP.init()
    .then(function () {
        return tClientKP.deposit({
            NotificationURL: 'http://127.0.0.1:4343/notification',
            EndUserID: '[email protected]',
            MessageID: '111112111221',
            Locale: 'es_ES',
            Amount: '1.00',
            Currency: 'EUR',
            SuccessURL: 'http://127.0.0.1:4343/success',
            FailURL: 'http://127.0.0.1:4343/fail',
            HoldNotifications: 1
        });
    })
    .then(function (response) {
        console.log(util.inspect(response, false, 20, true));
    })
    .fail(function (error) {
        console.log(util.inspect(error, false, 20, true));
    });
    //Callback style
    tClientKP.init(function(){
        tClientKP.deposit({
            NotificationURL: 'http://127.0.0.1:4343/notification',
            EndUserID: '[email protected]',
            MessageID: '111112111221',
            Locale: 'es_ES',
            Amount: '1.00',
            Currency: 'EUR',
            SuccessURL: 'http://127.0.0.1:4343/success',
            FailURL: 'http://127.0.0.1:4343/fail',
            HoldNotifications: 1
        },function(err, response){
            if (err){
                console.log(util.inspect(err, false, 20, true));
            }
            console.log(util.inspect(response, false, 20, true));
        });
    })

You should init, and it is a asyncronous process. This init loads your private and the trustly public keys, neccesary for all the request and responses, creation and verification.

Documentation

Basically to initialize, you should pass, the config object composed by:

• [required] 'privateKeyPath': Path to you private key
• [required] 'username': Your trustly api username
• [required] 'password': Your trustly api password
• [optional] 'publicKeyPath': Path to a public key (for the general cases you don't need it, i package the trusty public key)
• [optional] 'endpoint': By default it is autoselected depending of the environment, you can always send the endpoint you want.
• [optional] 'environment': By default i fill with development

The module have this 3 basic methods:

• 'deposit' : Create a deposit request.
• 'refund' : Create a refund request.
• 'createNotificationResponse' : Helper that verifies the data from truistly using the keys, and returns the data you need to response to every notification, returns an object.

The 2 basic methods are: deposit, refund. They uses the parameters described in trusty documentation. here (trustly docs)

Then you have a method to handle the notifications: 'createNotificationResponse'. Accepts a Json string or a Json with the notification, and returns you the correct data, then you simply need to send as a reponse in you notification listener. (see test/test-notification-server.js you have an example about it)

Also there are other functions to sign, verify the data, compose the request. Feel free to explore the code.

Errors

It will return always the same structure if an error happens:

    var error = {
        lastRequest: self._lastRequest,
        lastResponse: self._lastResponse,
        trustlyError: null,
        clientError: null
    };

Always you will have last request and response. If clientError is filled, mean all errors except trustly errors. If trustlyError is filled, it will catch all information about the trustly error in this format (Example):

    trustlyError = { 
        method: 'Deposit',
        uuid: 'dba2d98c-6c4e-4b9e-aa46-90027793aa14',
        message: 'ERROR_DUPLICATE_MESSAGE_ID',
        code: 637 
    };

Note: method and uuid can be null if the request contains a malformed JSON More information about the errors here (trustly docs)
