How to load JSON data in Google BigQuery using GET requests?

Question

Google Cloud Platform

Hello! Please help me with one issue.
Briefly, the task is to have a table in BigQuery with order IDs and their statuses. Our site gives 5 last orders at a time with this data. To get this information, you need to make a GET request https://site.ru/export-json.php. And in response, the site gives the last 5 orders with statuses in JSON format.
Next, you need to check which of the 5 order IDs are already in the BigQuery table and add only those that are not. You need to make a GET request every 5 minutes.
A big request to suggest a way and a bunch of Google services that you need to use in order to accomplish this task.
