Build a search and import wordpress plugin for Walmart Grocery

I want a plugin only for Walmart Grocery. I am also providing you the API i.e. https://grocery.walmart.com. I need the following functionality: 1. Keyword search - Search Walmart grocery products using a Keyword 2. Auto-populate all categories and subcategories. Also, provide a sync button, on click, it should refresh all the categories and subcategories from the API. 3. Search the product using categories and subcategories ​4​. Search Using Store-Name ​5. ​Search Using Store Location or Store ID (Multiple store IDs must be allowed) ​6​. Import and sync functionality - For example, I input the store ID, then import it to my website and also sync the data and stock availability​​. ​7​. Filter for Pick-up/Delivery. ​8. ​Price multiplier while importing the product​. ​9. Search shipping options (very important) meaning if I search for coffee form store XYZ, Walmart will show me if that item has in-store pickup (for that item from that store) or next day delivery, or instore pick up 2 days or next day shipping or whatever the available shipping options are. ​10. ​Add all to the import list after searching a store (see screenshot) ​11. ​Import product ​using product id or URL​ (see screenshot) 12. The import should not be duplicated (if I search tomorrow for coffee and it’s already imported it should not allow me to select checkbox (similar to that eBay example plugin) Check following plugin and screenshot for understanding requirements: This is for eBay but I need a very similar for Walmart grocery: [login to view URL] ​Simple and minimalistic​ design​, like the screenshot I shared and like the ebay plugin.
