ShopConnect allows you to have a product list, product detail page and a shopping cart with your Shopify products inside of your WordPress. The checkout, customer data and all products are still managed in Shopify.
<h4>Features</h4>
<ul>
<li>list of products</li>
<li>product detail pages with a template you can customize</li>
<li>cart menu on the side (visible once it contains a product)</li>
<li>product sync every two hours</li>
<li>custom permalinks for /products/ and /collections/</li>
<li>metafield support</li>
</ul>
Check the help section for all available shortcodes (product title, image, description, price, buy button, metafield, text input) and properties.
Note: 
* currently there is no pagination so for better performance only use it for smaller shops with a few products. 
* to style your products and lists you’ll have to use your own custom CSS. 
* check “ShopConnect – Help” how to setup the connection.
<h3>External services</h3>

Display Shopify products on your WordPress blog.
How it works?
A) Set up all the apis as directed by the App 
B) Set up two new pages on your WordPress website
Page #1 Set the permalink to shopify (or products, shop, catalogue etc.) and add code [wp-shopify type=”products” limit=”100″ url-type=”default”]
Page #2 Set the permalink to product (note there is no “s” at the end of the product in the url, the slug/permalink should be with exactly “product”) and insert code [wp-shopify-product] (this is where product redirect link to shopify store will work on your WordPress website)
