My PHP program cannot scrape my store - 403 Forbidden error

Hi,

I wrote a PHP web scraper to read all the pages and links in my store and save some data to a DB. The program gets a 403 Forbidden error on the first page (Home page).

How can I allow my program to read all my store pages, which are currently in development and not public. I tried removing the password but still, get the error.

Is there something else I can try?

Thanks!
