clickSign API

Question

I’m new to php, I need to do an integration with the Clicksign api, but I can’t do it at all, someone has already done this integration?

$document_key = "9955";
$name ="Juliete";
$email = "[email protected]";
$phoneNumber = "40028922";
$signer_key = "Moreira";
$message = "Documetno aprovado";


//Para criar um documento
$response = (new Clicksign())->createDocument($path, $clicksignPath = '/Contrato de Prestação de Serviços-123.pdf', $mimetype = 'application/pdf', $deadline = null, $autoClose = true, $locale = 'pt-BR', $sequence_enabled = false);


//Para criar um signatário
$response = (new Clicksign())->createSigner($email, $name, $phoneNumber, $documentation = false, $birthday = null, $has_documentation = false);


//Para adicionar um signatário ao documento
$response =  (new Clicksign())->signerToDocument( $document_key, $signer_key, $sign_as = 'approve', $message);
