SalesForce client for Nodejs

This node module provides a set of methods to interact against SalesForce's services. The module was created as part of KidoZen project, as a connector for its Enterprise API feature.

Installation

Use npm to install the module:

> npm install salesforce-api

API

Due to the asynchrounous nature of Nodejs, this module uses callbacks in requests. All callbacks have 2 arguments: err and data.

function callback (err, data) {
	// err contains an Error class instance, if any
	// data contains the resulting data
} 

Authentication

UserName and Password login

The module exports a Class and its constructor requires a configuration object with following properties

• username: Required string. End-user’s username.
• password: Required string. End-user’s password.

var SalesForce = require("salesforce-api");
var salesforce = new SalesForce();
salesforce.authenticate({
        username: "[email protected]",
        password: "secret"
    }, ...

Username and Password Login (OAuth2 Resource Owner Password Credential)

When OAuth2 client information is given to ctor. authenticate(username, password) uses OAuth2 Resource Owner Password Credential flow to login to Salesforce.

• username: Required string. End-user’s username.
• password: Required string. End-user’s password.
• oauth2: Required. OAuth2 information

var SalesForce = require("salesforce-api");
var salesforce = new SalesForce();
salesforce.authenticate({
        username: "[email protected]",
        password: "secret",
        oauth2 : {
            clientId : '...',
            clientSecret : '...',
            redirectUri : 'https://login.salesforce.com/services/oauth2/token'
        }
    }, ...

Access Token

After the authenticate API call, you can get Salesforce access token and its instance URL. Next time you can use them to establish connection.

var OAUTH2SessionInfo = {
      	instanceUrl : '<your Salesforce server URL (e.g. https://na1.salesforce.com) is here>',
      	accessToken : '<your Salesforce session ID is here>'
   		// you can find this values in the result of authenticate method
    };

var query = {
    credentials : OAUTH2SessionInfo,
    SOSQL: "SELECT Id from Account"
};

api.Query(query, function(err, result) {
	...
	...
	...
