how to integrate Assently api for e-signature transaction in PHP - php

Question

In my wp project, I am using Assently for e-signature implementation. Though I have an account and created a pdf form file to be filled by the user I just am not able to proceed a bit. I am finding documentation not clear.
Also, I am not clear about what needs to be done so that the user will be shown form to process the transaction.
So, any help/suggestions to proceed forward is appreciated.
I have tried the following based on assently-laravel. But it's asking me to login. What is an error here?
Code:
define('ASSENTLY_DEBUG', true);
define('ASSENTLY_KEY', 'key');
define('ASSENTLY_SECRET', 'secret-generated');
include_once('assently/Assently.php');
$assently = new Assently();
$assently->authenticate(ASSENTLY_KEY, ASSENTLY_SECRET);
$url = 'https://test.assently.com/api/v2/createcasefromtemplate';
$default = array(
'Id' => '5a0e0869-' . rand(1111, 9999) . '-4b79-' . rand(1111, 9999) . '-466ea5cca5ce'
);
$data = array(
'auth' => $assently->auth(),
'templateId' => '0e004e2b-b192-4ce2-8f47-d7a4576d7df6',
'newCaseId' => '5a0e0869-' . rand(1111, 9999) . '-4b79-' . rand(1111, 9999) . '-466ea5cca5ce',
'agentUsername' => ''
);
$data = array(
'json' => $data
);
$options = array(
'http' => array(
'header' => "Content-type: application/json; charset=utf-8\r\n",
'method' => 'POST',
'content' => http_build_query($data)
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
echo '<pre>';
print_r($result);
die;

create this class inside assently folder
use Assently\AssentlyCase;
use Exception;
class CustomAssentlyCase extends AssentlyCase
{
public function createFromTemplate($data)
{
$default = [
'newCaseId' => '5a0e0869-'.rand(1111, 9999).'-4b79-'.rand(1111, 9999).'-466ea5cca5ce'
];
$json = array_merge($default, $data);
try{
$response = $this->client->post($this->url('createcasefromtemplate'), [
'auth' => $this->assently->auth(),
'json' => $json
]);
}catch(Exception $e){
print_r($e->getMessage());
}
return $response;
}
}
Use
define('ASSENTLY_DEBUG', true);
define('ASSENTLY_KEY', 'key');
define('ASSENTLY_SECRET', 'secret-generated');
include_once('assently/Assently.php');
include_once('assently/CustomAssentlyCase.php');
$assently = new Assently();
$assently->authenticate(ASSENTLY_KEY, ASSENTLY_SECRET);
$data = array(
'templateId' => '0e004e2b-b192-4ce2-8f47-d7a4576d7df6',
'newCaseId' => '5a0e0869-'.rand(1111, 9999).'-4b79-'.rand(1111, 9999).'-466ea5cca5ce',
'agentUsername' => 'agentUsername' // PUT your agent username here it is required
);
$customAssentlyCase = new CustomAssentlyCase($assently);
$result = $customAssentlyCase->createFromTemplate($data);
print_r($result);
Try this, though not tested but should work. Good luck.
