wp_remote_post and form post

Actually it is more general question but now i am trying to use it on wordpress site so I preferred to post it here.

I am trying to understand the difference between remote post and form post.

When I query a string and post it to remote server, I get the result as string and with “print $response” see it on browser console. But I want it to be displayed as html on browser. Am I expecting wrong thing or could i do such thing?

Basically I want to see raw response as html.

EDIT

In case of being more expressive..
I am trying to write credit card payment gateway inside woocommerce

Inside process_payment function which is called at the end of customer order, I am posting all info to bank server like below:

public function process_payment( $order_id ) {
    global $woocommerce;
    ....
    ...
    $okUrl = "http://localhost/xxx/wc-api/paymentpos/";         
    $failUrl = "http://localhost/xxx/wc-api/paymentpos/";
    $payload = array(.....);
         $response = wp_remote_post( $environment_url, array(
        'method'    => 'POST',
        'body'      => http_build_query( $payload ),
        'timeout'   => 45,
        'sslverify' => false,
    ) );
    $respbody = wp_remote_retrieve_body($response);
    print $respbody;
    }

After that, bank server should reply to payment_callback() which is like

public function payment_callback(){

    global $woocommerce;

    wc_add_notice( 'OK', 'success' );
    .....
    exit();     
}

I am getting $respbody as below on console.

{"result":"failure","messages":"","refresh":"false","reload":"false"}

This response should trigger payment_callback() function. Manually I could trigger payment_callback() like http://localhost/xxx/wc-api/paymentpos/. But this response could not trigger. I am suspicious about I could handle wp_remote_post response correctly.
