Answer 1

If you want to connect any third party service, most of the chances they(Acumatica) have API access for their(Acumatica) system. So, you need to use their API to push and pull the data from anywhere(Magento).

E.g) I'm not aware of Acumatica, But If I'm in your place I do the below things

1. I found the Acumatica provide REST API support
2. So, I'll use the REST api to authenticate the Acumatica (you can use php CURL or Magento in built http client for authentication)
3. After that I used the same http client and will do the push/pull operations.

Answer 2

X consuming Magento

REST with Oauth1.

Generate an Integration token from the backend.

The connection can be tested with postman or any other tool. the api-consumer connects just like you would.

public function __construct(
    Context $context,
    \Magento\Framework\HTTP\Client\Curl $curl

    $this->_curl = $curl;
    parent::__construct($context);
}

public function execute()
{
    //if the method is get
    $this->_curl->get($url);
    //if the method is post
    $this->_curl->post($url, $params);
    //response will contain the output in form of JSON string
    $response = $this->_curl->getBody();
}
