Hello, I need to integrate your API so I can do the following
1. Add products to my shop and let users be able to search from them.
2. Get details like product information, pictures, description, pricing etc.. using the product id.
3. If possible, also be able to access the products from other apps that use Shopify
4. Add items to cart and proceed to payment
I've already looked at some of your documentation, I couldn't figure out how to get started with this from that. Please guide me through this..
