New integration method - patch delta!
Patch delta catalog format
Customers integrating with our catalog feed methods (HTTP or FTP) have the ability to provide product data for products and variations through full feeds (sync) as well as partial or update files (deltas). This makes it easy for anyone - integration engineers, merchants or product managers - to download and validate the catalog from the dashboard (available here with admin access) in order to answer questions about what's been sent to Constructor.
While deltas allowed customers to update just those items with changes, there is an assumption that all of the data about the items (products or variations) being updated is sent whenever any of the item data changed. For customers implementing complicated BOPIS (buy online, pick up in store) store availability data with feeds, this was a challenge.
As a result, we released a new catalog capability - patchdelta. This catalog format allows updating some of the data for some of the products and is covered in more depth here.
