Delta Sync APIs refer to application programming interfaces (APIs) that facilitate the synchronization of data by transmitting only the changes (or deltas) between the current and previous versions of the data.

Delta Sync APIs work by identifying the differences or changes between the current state of data and the previous state. Instead of sending the entire dataset, these APIs transmit only the modifications, additions, or deletions (the deltas) that have occurred since the last synchronization.

If the lastupdate query parameter is set to 2024-01-19, then it will retrieve records that have been updated since that date. Delta Syncing is implemented for the below APIs.

a) Get all Categories APIs.
Resource URI: GET /printproducts/categories?lastupdate=2014-01-19&time=15:10:00
In Response it will return all categories that has been updated since lastupdate date.

b) Fetch products of specific Category APIs.
Resource URI: GET /printproducts/categories/{category_uuid}/products?lastupdate=2014-01-19&time=15:10:00
In Response it will return all products that has been updated since lastupdate date.

c) Product APIs.
Resource URI: GET /printproducts/products?lastupdate=2014-01-19&time=15:10:00
In Response it will return all products that has been updated since lastupdate date.

d) Product Feed APIs.
Resource URI: GET /printproducts/productsfeed?lastupdate=2014-01-19&time=15:10:00
In Response it will return all products that has been updated since lastupdate date.
