HelloSign PHP SDK

This is the official PHP SDK for HelloSign's API. View API Documentation and Examples.

Installation

Requirements

The latest version of the SDK requires PHP version 8.0 or higher. For PHP 7.x use SDK version 3.7.*

You can import this SDK into your library two ways, either through including the base HelloSign.php file into your project or using Composer.

To use Composer:

• First, install Composer if you don't have it already

  curl -sS https://getcomposer.org/installer | php

• Create a composer.json file and add the following:

  {
      "require": {
          "hellosign/hellosign-php-sdk": "^3.0"
      }
  }

• Install hellosign-php-sdk package via Composer

  php composer.phar install

• Include the library in your script

  require_once 'vendor/autoload.php';

• See below for how to configure your Client class.

Configuration

All HelloSign API requests can be made using the HelloSign\Client class. This class must be initialized with your authentication details such as an API key (preferred), email/password combo, or OAuth credentials.

API key Config

$client = new HelloSign\Client($apikey);

Email/Password Config

$client = new HelloSign\Client($email_address, $password);

Oauth Config

$client = new HelloSign\Client($oauth_token); //instance of HelloSign\OAuthToken

Your app users are almost ready to start signing! See below for the most common use cases for this wrapper.

Usage

You can test your authentication by calling

$account = $client->getAccount();

Retrieving fields returned from the API

Using magic methods

$signature_request->title;

Or if you want to get all attributes in an array

$signature_request->toArray();

Creating a Signature Request

$request = new HelloSign\SignatureRequest;
$request->enableTestMode();
$request->setTitle('NDA with Acme Co.');
$request->setSubject('The NDA we talked about');
$request->setMessage('Please sign this NDA and let\'s discuss.');
$request->addSigner('[email protected]', 'Jack');
$request->addSigner('[email protected]', 'Jill');
$request->addCC('[email protected]');
$request->addFile('nda.pdf'); //Adding file from local

$response = $client->sendSignatureRequest($request);

To specify a URL to a remote file instead use:

$request->addFileURL('PUBLIC_URL_TO_YOUR_FILE');

If you are using Text Tags in your document, you can enable and configure them through the respective methods:

$request->setUseTextTags(true);
$request->setHideTextTags(true);

Or if you want to set Form Fields per Document:

$request->setFormFieldsPerDocument(
            array(
                array( //document 1
                    array( //field 1
                        "api_id"=> $random_prefix . "_1",
                        "name"=> "",
                        "type"=> "text",
                        "x"=> 112,
                        "y"=> 328,
                        "width"=> 100,
                        "height"=> 16,
                        "required"=> true,
                        "signer"=> 0
                    ),
                    array( //field 2
                        "api_id"=> $random_prefix . "_2",
                        "name"=> "",
                        "type"=> "signature",
                        "x"=> 530,
                        "y"=> 415,
                        "width"=> 150,
                        "height"=> 30,
                        "required"=> true,
                        "signer"=> 1
                    ),
                ),
            )
        );

Retrieving a User's Templates

The HelloSign API provides paged lists for user templates and signature requests. These lists are represented as objects that can be iterated upon.

$templates = $client->getTemplates($page_number);
foreach ($templates as $template) {
    echo $template->getTitle() . "\n";
}

Creating a Signature Request from a Template

$request = new HelloSign\TemplateSignatureRequest;
$request->enableTestMode();
$request->setTemplateId($template->getId());
$request->setSubject('Purchase Order');
$request->setMessage('Glad we could come to an agreement.');
$request->setSigner('Client', '[email protected]', 'George');
$request->setCC('Accounting', '[email protected]');
$request->setCustomFieldValue('Cost', '$20,000');

$response = $client->sendTemplateSignatureRequest($request);

Checking the Status of a Signature Request

$response = $client->getSignatureRequest($signature_request_id);
if ($response->isComplete()) {
    echo 'All signers have signed this request.';
} else {
    foreach ($response->getSignatures() as $signature) {
        echo $signature->getStatusCode() . "\n";
    }
}

Creating an Embedded Signature Request to use for Embedded Signing

Refer to the (Embedded Signing Walkthrough)[https://app.hellosign.com/api/embeddedSigningWalkthrough] for more details.

// Create the SignatureRequest or TemplateSignatureRequest object
$request = ...

// Turn it into an embedded request
$embedded_request = new HelloSign\EmbeddedSignatureRequest($request, $client_id);

// Send it to HelloSign
$response = $client->createEmbeddedSignatureRequest($embedded_request);

// Grab the signature ID for the signature page that will be embedded in the
// page (for the demo, we'll just use the first one)
$signatures   = $response->getSignatures();
$signature_id = $signatures[0]->getId();

// Retrieve the URL to sign the document
$response = $client->getEmbeddedSignUrl($signature_id);

// Store it to use with the embedded.js HelloSign.open() call
$sign_url = $response->getSignUrl();

Creating an Embedded Template draft

$template = new HelloSign\Template();
$template->enableTestMode();
$template->setClientId($client_id);
$template->addFile('nda.pdf');
$template->setTitle('Test Title');
$template->setSubject('Test Subject');
$template->setMessage('Test Message');
$template->addSignerRole('Test Role');
$template->addMetadata('custom_id', '1234');

$response = $client->createEmbeddedDraft($template);

Creating an Unclaimed Draft to use for Embedded Requesting

$draft = new HelloSign\UnclaimedDraft($request, $client_id);
// optionally change it to a self-signing draft with $draft->setType("send_document");
$response = $client->createUnclaimedDraft($draft);

// Store it to use with the embedded.js HelloSign.open() call
$sign_url = $response->getClaimUrl();

Enabling OAuth

// If the account does not exist
if !($client->isAccountValid($email)) {
    // Create new account
    $account = $client->createAccount(
        new HelloSign\Account($email),
        $client_id,
        $client_secret
    );

    // Get OAuth token
    $token = $account->getOAuthData();
} else {
    // Create the OAuthTokenRequest object
    $oauth_request = new HelloSign\OAuthTokenRequest(array(
        'code'          => $code,
        'state'         => $state,
        'client_id'     => $client_id,
        'client_secret' => $client_secret
    ));

    // Request OAuth token for the first time
    $token = $client->requestOAuthToken($oauth_request);
}

// Export token to array, store it to use later
$hellosign_oauth = $token->toArray();

// Populate token from array
$token = new HelloSign\OAuthToken($hellosign_oauth);

// Refresh token if it expired
$client->refreshOAuthToken($token);

// Provide the user's OAuth access token to the client
$client = new HelloSign\Client($token);

Displaying warnings

Any warnings returned from the API can be accessed via the returned object / list via the getWarnings method:

  $response = $this->client->getSignatureRequests();
  print_r($response->getWarnings());

Testing

This project contains PHPUnit tests that check the SDK code and can also be referenced for examples. Most are functional and integrated tests that walk through real user scenarios.

In order to pass the unit tests, you will need:

1. The API Key for a confirmed HelloSign account
2. The client ID and secret key from a confirmed HelloSign API App
3. A HelloSign subscription (to create a team)
4. A HelloSign API subscription (to access paid API endpoints)
5. A template with 1 signer role named 'Signer'
6. A Team with 1 additional team member

*** WARNING: these tests will add and remove users from your team. Use with caution.

To run the tests

• Copy file phpunit.xml.dist to phpunit.xml
• Edit the new file and enter your values for API_KEY, CLIENT_ID, CLIENT_SECRET, CALLBACK_URL, API_URL, AND OAUTH_TOKEN_URL
• Run ./vendor/bin/phpunit
