docusign-esign

DocuSign Node Client

NPM module that wraps the DocuSign API

Documentation about the DocuSign API

Documentation about this package

You can sign up for a free developer sandbox.

Requirements

Node 4 or later.

Installation

NPM Package Manager

Install the client locally: npm install docusign-esign --save --save-exact (note you may have to use sudo based on your permissions)

Alternatively you can just copy the source code directly into your project.

Dependencies

Usage

To initialize the client, make the Login API Call and send a template for signature:

SDK version 3.x.x

Using DocuSign passport-based Oauth Client for Express

run node test/OAuthClientTests.js and then open http://localhost:3000/auth.

const express = require('express');
const passport = require('passport');
var session = require('express-session');
var docusign = require('../src/index');

const app = express();
const port = process.env.PORT || 3000;
const host = process.env.HOST || 'localhost';

app.use(session({
  secret: 'secret token',
  resave: true,
  saveUninitialized: true
}));

app.use(passport.initialize());
app.use(passport.session());

var hostUrl = 'http://' + host + ':' + port;

// Configure Passport
passport.use(new docusign.OAuthClient({
  sandbox: true,
  clientID: 'YOUR_CLIENT_ID',
  clientSecret: 'YOUR_CLIENT_SECRET',
  callbackURL: hostUrl + '/auth/callback'
},
  function (accessToken, refreshToken, user, done) {
    // Here we're just assigning the tokens to the user profile object but we
    // could be using session storage or any other form of transient-ish storage
    user.accessToken = accessToken;
    user.refreshToken = refreshToken;
    return done(null, user);
  }
));

app.get('/auth', function (req, res) {
  passport.authenticate('docusign'/*, {state: 'optional state'}*/)(req, res);
});

app.get('/auth/callback', function (req, res) {
  passport.authenticate('docusign'/*, {state: 'optional state'}*/, function (err, user) {
    if (err) {
      return res.send(err);
    }
    if (!user) {
      return res.redirect('/auth');
    }

    // getting the API client ready
    var apiClient = new docusign.ApiClient();
    // for production environment update to "www.docusign.net/restapi"
    var BaseUrl = 'https://demo.docusign.net/restapi';
    apiClient.setBasePath(BaseUrl);
    apiClient.addDefaultHeader('Authorization', 'Bearer ' + user.accessToken);

    // creating an instance of the authentication API
    var authApi = new docusign.AuthenticationApi(apiClient);
    var loginOps = {};
    loginOps.apiPassword = 'true';
    loginOps.includeAccountIdGuid = 'true';
    // making login call. we could also use DocuSign OAuth userinfo call
    authApi.login(loginOps, function (error, loginInfo, response) {
      if (error) {
        return res.send(error);
      }
      if (loginInfo) {
        // list of user account(s)
        // note that a given user may be a member of multiple accounts
        var loginAccounts = loginInfo.loginAccounts;
        var loginAccount = loginAccounts[0];
        var baseUrl = loginAccount.baseUrl;
        var accountDomain = baseUrl.split('/v2');

        // below code required for production, no effect in demo (same domain)
        apiClient.setBasePath(accountDomain[0]);
        docusign.Configuration.default.setDefaultApiClient(apiClient);

        // return the list of accounts to the browser
        return res.send(loginAccounts);
      }
    });
  })(req, res);
});

app.listen(port, host, function (err) {
  if (err) {
    throw err;
  }

  console.log('Your server is running on http://' + host + ':' + port + '.');
});

Authentication

Service Integrations that use Legacy Header Authentication

(Legacy Header Authentication uses the X-DocuSign-Authentication header.)

1. Use the Authentication: login method to retrieve the account number and the baseUrl for the account. The url for the login method is www.docusign.net for production and demo.docusign.net for the developer sandbox. The baseUrl field is part of the loginAccount object. See the docs and the loginAccount object
2. The baseUrl for the selected account, in production, will start with na1, na2, na3, eu1, or something else. Use the baseUrl that is returned to create the basePath (see the next step.) Use the basePath for all of your subsequent API calls.
3. As returned by login method, the baseUrl includes the API version and account id. Split the string to obtain the basePath, just the server name and api name. Eg, you will receive https://na1.docusign.net/restapi/v2/accounts/123123123. You want just https://na1.docusign.net/restapi
4. Instantiate the SDK using the basePath. Eg ApiClient apiClient = new ApiClient(basePath);
5. Set the authentication header as shown in the examples by using Configuration.Default.AddDefaultHeader

User Applications that use OAuth Authentication

1. After obtaining a Bearer token, call the OAuth: Userinfo method. Obtain the selected account's base_uri (server name) field. The url for the Userinfo method is account-d.docusign.com for the demo/developer environment, and account.docusign.com for the production environment.
2. Combine the base_uri with "/restapi" to create the basePath. The base_uri will start with na1, na2, na3, eu1, or something else. Use the basePath for your subsequent API calls.
3. Instantiate the SDK using the basePath. Eg ApiClient apiClient = new ApiClient(basePath);
4. Create the authentication_value by combining the token_type and access_token fields you receive from either an Authorization Code Grant or Implicit Grant OAuth flow.
5. Set the authentication header by using Configuration.Default.AddDefaultHeader('Authorization', authentication_value)

Testing

Unit tests are available in the Test folder.
