Hey @caro_2021
I think your best way to go for the first is to use the WIX automation and set the trigger for any time an order is made or a product is created on the WIX store. As an action you use the Shopify Actions Create Order/Create Product (see here).
Can you describe in more detail what you want to achieve for the second one?
Hey! How did you get on here? It looks like there are no direct integrations into Wix, however, you may be able to use their REST API to update the shipping
You can use Zapier’s webhook feature to create a PUT request on the Shipping Address

I hope that points you in the right direction - Feel free to reach out to me via my website here if you need any help with implementation: www.andywingrave.com
