- Additional Notes

Installation

First time using npm? Read more about installing npm packages [here] (https://docs.npmjs.com/downloading-and-installing-packages-locally).

Install from npm:
```sh


Optionally, to scaffold your package.json first

npm init

npm install hellosign-sdk

Optionally, to install testing / development dependencies

cd node_modules/hellosign-sdk
npm install
``

Install from code:
``sh
git clone https://github.com/HelloFax/hellosign-nodejs-sdk.git
cd hellosign-nodejs-sdk


install dependencies


npm install
``

Configuration

In your Node application, require hellosign-sdk (or the path to the sdk folder if not using npm) and pass authentication information to initialize it:

``javascript
// Initialize using api key
var hellosign = require('hellosign-sdk')({key: 'YOUR API KEY HERE'});

OR

// Initialize using email and password
var hellosign = require('hellosign-sdk')({username: 'your_email_address', password: 'your_password'});

OR

// Initialize for embedded requests using your api key, client id, and (optionally, for OAuth) client secret
var hellosign = require('hellosign-sdk')({key: 'YOUR API KEY HERE', client_id: 'your client id', client_secret: 'your client secret'});

``

For initialization for Oauth app-specific calls, see the Oauth section below.

Usage

Each function in the SDK is called from your initialized hellosign object, followed by the module name, and then the method.

`javascript
hellosign.template.list();
`

See below for a list of modules and their associated endpoint methods.

$3

The results of each method can be accessed either as a callback, or a promise:

Callback style responses are included as the last (or only, in the case of no others) parameter in a call:

`javascript
hellosign.signatureRequest.send({/options/}, function(err, response){
if (err) {
//do something with error
} else {
//parse response
}
});
`

Promise style access is through Javascript!

`javascript
hellosign.signatureRequest.send({/options/})
.then(function(response){
//parse response
})
.catch(function(err){
//do something with error
})
.finally(function(){
//optionally do yet another thing
});
`

Returned promises are then-able, or can be returned for later resolution.




Modules

Modules in the SDK are as follows:

- Account
- Signature Request
- Embedded
- OAuth
- Team
- Template
- Reports
- Unclaimed Draft
- API App

$3

#### Get current account information

``javascript
hellosign.account.get()
.then();
``

#### Update your account information

``javascript
var new_callback_url = "https://www.example.com/callback"
hellosign.account.update({callback_url: new_callback_url})
.then();
``

#### Create a new HelloSign account

``javascript
var email: "new_user@example.com";

hellosign.account.create({
email_address: email
})
.then();
``

#### Verify if an account exists (only for paid API users)

``javascript
var email: "possibly_existing_user@example.com";
var account_id: '12738igfe87egqo22';

hellosign.account.verify({email_address: email,})
.then();

hellosign.account.verify({account_id: email,})
.then();
``

#### Get an existing Signature Request by ID

``javascript
hellosign.signatureRequest.get("fa5c8a0b0f492d768749333ad6fcc214c111e967")
.then();
``

#### Get a list of your Signature Requests

``javascript
hellosign.signatureRequest.list()
.then(function(res){
console.log(res.signature_requests);
});
``

This endpoint can optionally receive the parameters page, and page_size, passed in as an options object:

``javascript
hellosign.signatureRequest.list({page: 2, page_size: 15})
``

This endpoint can optionally be used to query and search for items such as page, title, and from passed in as an options object:

``javascript
const opts = {
page: 1,
query: 'title:Test +title AND from:me'
}

hellosign.signatureRequest.list(opts).then((res) => {
console.log(res);
}).catch((err) => {
console.error(err);
});
``

#### Gives you insights into user activity and document status

#### Get a Report
``javaScript
const opts = {
test_mode: 1,
start_date: '09/13/2020',
end_date: '09/20/2020',
report_type: ['user_activity', 'document_status']
};

client.reports.get(opts).then((res) => {
console.log('what is the response?', res);
}).catch((err) => {
console.error('what is the error?', err);
});
``

$3

#### Get the user to authorize your app

You'll need to create an API app, and add OAuth support, and then use the URL provided to authorize users for your application.
When you do so, you'll get a state and code value that can be used as below to get an OAuth access token.

See our OAuth 2.0 walkthrough for more details.

#### Get an app-specific access token
``javascript
var hellosign = require('./hellosign.js')({key: 'YOUR API KEY HERE', client_id: 'your client id', client_secret: 'your client secret'});

hellosign.oauth.getToken({state : '53b02619', code : '1d0219ea3363aa67'})
.then();
``

#### Make API calls using your OAuth token:

Use the access token to instantiate an app-specific HelloSign object:

``javascript
var hellosignOauth = require('./hellosign-nodejs-sdk/lib/hellosign.js')({oauthToken: 'YOUR_ACCESS_TOKEN'});
``

You can then use the HelloSign object you've created with the Oauth key to perform requests with that key:

``javascript
var options = {
test_mode : 1,
title : 'NDA with Acme Co.',
subject : 'The NDA we talked about',
message : 'Please sign this NDA and then we can discuss more. Let me know if you have any questions.',
signers : [
{
email_address : 'jack@example.com',
name : 'Jack',
order : 0
},
{
email_address : 'jill@example.com',
name : 'Jill',
order : 1
}
],
cc_email_addresses : ['lawyer@example.com', 'lawyer@example2.com'],
files : ['nda.pdf']
};

hellosignOauth.signatureRequest.send(options)
.then();
``

#### Refresh your OAuth token

From the HelloSign instance with your app's client_id and secret set, you can also use the refresh token you got in the first token call above to fetch a new access token for your use:

``javascript
hellosign.oauth.refreshToken({refresh_token : 'YOUR_REFRESH_TOKEN'})
.then();
``

$3

#### Get your team's information
``javascript
hellosign.team.get()
.then(function(res){
console.log(res.team);
});
``

#### Create a team (if you don't have one)
``javascript
var team_name = 'Radion 6'
hellosign.team.create({name: team_name})
.then(function(res){
console.log(res.team);
});
``

#### Update team
``javascript
var newName = 'The Mr. T Team';
hellosign.team.update({name: newName})
.then(function(res){
console.log(res.team);
});
``

``javascript
hellosign.team.destroy().then((res) => {
console.log('what is the statusCode?', res.statusCode);
console.log('what is the statusMessage?', res.statusMessage);
}).catch((err) => {
console.error('what is the error?', err);
});
``

#### Add a team member
``javascript
var memberEmail = 'benedict@cumberbatch.org';
hellosign.team.addMember({email_address: memberEmail})
.then(function(res){
console.log(res.team);
});
``

#### Remove a team member
``javascript

// handle error
});
``

#### List API App
``javascript
hellosign.apiApp.list().then((res) => {

});
``

#### Create API App
``javascript
const opts = {
name: 'My Cool App',
domain: 'http://www.example.com',
callback_url: 'http://www.example.com/callback',
white_labeling_options: '{"primary_button_color":"#ff0000","primary_button_text_color":"#000000"}'

#### Delete API App
``javascript
hellosign.apiApp.delete(clientId).then((res) => {
console.log('what is the statusCode?', res.statusCode);
console.log('what is the statusMessage?', res.statusMessage);
}).catch((err) => {
console.error('what is the error?', err);
});
``

Warnings

Any warnings returned from the api will be accessible on the response object returned:

``javascript
hellosign.account.get()
.then(function(res){
console.log(res.warnings);
});
``

Status codes

On any response object, you can inspect the statusCode and statusMessage properties to get HTTP status information.

This is especially useful for endpoints that don't return any JSON information, like cancel:

``javascript
hellosign.signatureRequest.cancel('fa5c8a0b0a492d768749333ad6fcc214c111e967')
.then(function(response){
console.log(response.statusCode);
console.log(response.statusMessage);
});
``

Tests

Unit tests can be run simply by executing:
``sh
npm test
``

Mocked functional tests are coming soon. Look inside the repo for a sneak peak.

Additional notes

$3

We do not allow app callbacks (event or OAuth) to be set to localhost. However it is still possible to test callbacks against a local server. Tunneling services such as ngrok (http://ngrok.com) can help you set this up.
