<?php
//start a session
session_start();
//Webhook enviado por shopify
$webhookContent= "";
$webhook= fopen('php://input' , 'rb');
while (!feof($webhook)) {
$webhookContent .= fread($webhook, 4096);
}
fclose($webhook);
$data= json_decode($webhookContent,true);
//guardar datos ordenes
$file = 'shipping_innata.txt';
$print = print_r($webhookContent, true);
file_put_contents($file, $print, FILE_APPEND | LOCK_EX);
//obtener desde headers el dominio de shopify
$domain_header= $_SERVER['HTTP_X_SHOPIFY_SHOP_DOMAIN'];
//consulta en base 99min
$db = mysqli_connect("localhost", "root", "plas711", "minut_api");
//comprobar carrier
$shipping= $data ['shipping_lines']['0']['code'];

If I understand you correctly, you're wondering why do you get several requests from Shopify instead of just one.
I've faced the same problem recently, and I think it's a feature of Webhooks mechanism you have to deal with.
Consider this post: https://ecommerce.shopify.com/c/shopify-apis-and-technology/t/webhook-url-is-called-between-2-4-times-220007
Bottomline. You should expect Shopify will hit your endpoint more than once and you have to manage this by yourself to avoid duplicating entities and stuff.
