                "Prénom":"'.$nom.'",
            },
                "field_boolean_data": {},
                "field_date_data": {},
            },
            "actions": [
            {
               "recipient_name": "'.$nom.'",
               "recipient_email": "'.$mail.'",
               "action_id": "16183000000061014",

        }';
    $POST_DATA = array(
    'data' => $requestData,
    );

    $curl = curl_init("https://sign.zoho.com/api/v1/templates/16183000000061001/createdocument");
    curl_setopt($curl, CURLOPT_TIMEOUT, 30);
    curl_setopt($curl, CURLOPT_HTTPHEADER, array(
    'Authorization:Zoho-oauthtoken <OauthToken>',
    ));
    curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "GET");
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $POST_DATA);
    $response = curl_exec($curl);
    echo $response;
    $jsonbody = json_decode($response);// contain filed tyes response
    if($jsonbody->status == "success")
    {
    $created_request_id = $jsonbody->requests->request_id//Save the ID from the response to update later
    $status = $jsonbody->requests->request_status;
    echo $status;
    }
    else //Error check for error
    {
    echo $jsonbody->message;
    }    
    curl_close ($curl);
