[Plugin: WooCommerce] Api help

Hello,

I have been doing great with WP. But now, when I started to create my e-shop, with a suplier, which gave me the API ID and API secret (some other information, which i hardly understand), I am no longer finding my way to the succes. What should I do with those keys? They say, that, when I porperly install it, the e-shop will automatically update with their new products, descriptions and so on. I use WooCommerce.

Please, help me,
I would be gratefull,
Thank you!
