Need Help - linking shoe size availabilities from another website to mine

[deshawnl]

Hi guys,

So I run a business customizing shoes, and I've been looking for a way to link the shoe size availabilities of the shoe sizes on my website to another where I source the base products from - for example SPORTSDIRECT or JD SPORTS, or even sportsshoes for example.

Is this an easy task? How would I go about doing this?

Ideally, it would automatically update with changes to the websites meaning that items would show out of stock if they are also out of stock on those respective websites.

Thanks
