Requirements

PHP 7.1 or newer

Install

composer require signnow/api-php-sdk

Setting up

Register an annotation loader if only there is doctrine/annotations less v2.0 in use. This method is deprecated and will be removed in doctrine/annotations 2.0 so annotations will be autoloaded in 2.0.

AnnotationRegistry::registerLoader('class_exists');

Create the instance of Entity Manager:

use SignNow\Api\Service\Factory\EntityManagerFactory;
use SignNow\Api\Service\Factories\TokenFactory;

// configuring entity manager with the basic token 
$entityManager = 
    (new EntityManagerFactory())->create(
         'https://api.signnow.com',
         (new TokenFactory())->basicToken('YOUR_BASIC_TOKEN_STRING')
     );

use SignNow\Api\Service\Factory\EntityManagerFactory;
use SignNow\Api\Service\Factories\TokenFactory;

// configuring entity manager with the bearer token
$entityManager = 
    (new EntityManagerFactory())->create(
         'https://api.signnow.com',
         (new TokenFactory())->bearerToken('BEARER_TOKEN_STRING')
     );

Setup update http method for Entity Manager:

use SignNow\Rest\Http\Request;

$entityManager->setUpdateHttpMethod(Request::METHOD_PUT);

Also, it is possible to use the wrapper using OAuth authorization

use SignNow\Api\Action\OAuth as SignNowOAuth;

$auth = new SignNowOAuth('https://api.signnow.com');

$entityManager = $auth->bearerByPassword('YOUR_BASIC_TOKEN_STRING', 'username', 'password');

Tests

SignNow PHP SDK is covered with functional tests using Codeception and Phiremock. Phiremock allows us to mock calls to SignNow API. All the calls pass at 127.0.0.1 port 8008. Ensure that this port is not in use in the local machine before running test.

All the tests execution in console:

vendor/bin/codecept run functional

A single test execution in console:

vendor/bin/codecept run tests/functional/Template/CreateCest.php

Also, tests might be useful as examples of using SignNow PHP SDK.

Sandbox

Directory sandbox contains php script to taste some SDK feature. Please, provide this scripts with your personal credentials, write some code or use existing code. Execute sandbox script in console:

php sandbox/execute.php

Entity manager

Entity manager is the main class which controls communication with 3rd party REST API where JSON is used as main data type. It's responsible for saving objects to and fetching objects from the API.

Each entity is described by:

API resource url (via HttpEntity annotation),
API payload (via properties and theirs types),
API response type (via ResponseType annotation, optional).

Examples & use cases

Upload Document to SignNow

use SignNow\Api\Entity\Document\Upload as DocumentUpload;

$uploadFile = (new DocumentUpload(new \SplFileInfo('realFilePath')));
$document = $entityManager->create($uploadFile);

Download Document from SignNow

use SignNow\Api\Entity\Document\Download as DocumentDownload;

$documentUniqueId = 'e896ec9311a74a8a8ee9faff7049446fe452e461';

$document = $entityManager->get(
    new DocumentDownload(),
     [
        'id' => $documentUniqueId,
     ],
     [
        'type' => 'collapsed',
     ]);

Actions

Actions - this is just a new abstraction layer above Entity Manager and implemented as services. So that, both Entity Manager and Actions are equivalent options to use SignNow API. See actions in directory src/Action.

OAuth 2.0

// type can be 'collapsed' or 'zip' 

// if need table containing the document's history set with_history=1
$entityManager->get(new DocumentDownload(), ['id' => $documentUniqueId], ['type' => 'collapsed', 'with_history' => 1]);
