I am in logistics business delivering packags from USA to Latin American countries like(Honduras, Colombia …). Have a warehouse in USA.

I want my users to be able to search and select product from Amazon and then place order to us.

We then make actual order to Amazon with shipping address as our warehouse and then deliver to the user with our logistics service.

I am exploring best and easy option for our users to select products and place order with multiple items.

1. Own ecom website

we build our website with products listed users can browse and select and place order they see Amazon price with our Shipping costs we place the order to Amazon based on product selected and deliver

Issues

Access to AMAzon product API to show products with current prices

2. App with Amazon embedded

build a App where we have amazon embedded in WebView users can easily select and put product in cart When placing order we get products in cart and place internal order then proceed with Amazon order to our warehouse and deliver

Issues

Apple rejected the APP saying we need a Amazon approval before we can show any 3rd party website content in our APP

3. Other weird solutions

Use Scrapers to get product search/listings maybe build some extension to show our shipping prices and get products for ordering

So please help me find out best way to solve this issue.
