What is the difference between Shopify server-side collections integration vs Tagalys API integration?

There are two methods by which collections can be integrated with Tagalys: either through the Shopify server-side or by using Tagalys APIs. Kindly refer to the table below that outlines the differences between these two approaches.

The rest of the capabilities are common across both methods of integration. 

Please note that implementing the Tagalys APIs integration will require integration efforts from your development team. In contrast, if you choose the Shopify server-side integration method, you can activate collections with Tagalys within 24 to 48 hours after installing the app, assuming your store is using a Shopify native theme without any customizations.
