The batch product searching functionality is an extension of the existing product search functionality to cater for distributors that may want to download the ATDW product data to their own local database. Distributors that use ATDW product data in this way are known as Batch distributors. This functionality was supported in ATWS and has now been implemented in ATLAS version 3.0.0.
Get all listings that have been updated since 1 January 2018http://[host]/api/atlas/products?key=[key]&delta=2018-01-01
To obtain a list of changes that have occurred after a certain time and date you can use the 'delta' parameter.
The distributor will periodically query for updates of products they are interested in so that they can download those changes to their local database. A new “delta” parameter has been introduced that will be used in conjunction with the original product search URL to retrieve only any updated products since the last time a distributor queried ATLAS. This approach is strongly recommended as distributors will only need to retrieve a small set of product information periodically.
Assuming that the distributor last requested product information at 9am on the 1 January 2018 then the periodic query would be:
The date format is yyyy-mm-dd. Optionally, if an hourly update is required the format is yyyy-mm-dd hh:mm:ss.
The response from a delta parameter query has a new field ‘status’. This field can have one of three values
The default data set that is returned can be tailored to your needs by using the fl parameter
(please refer to the Search query API guide)
For an ACTIVE ATDW product, if the supplied product details are not sufficient to be used by the distributor, they will further make a product call to get the full details of a product on a product id basis.
This will not be required for the other product status and should result in those products being removed or marked as unavailable in the distributors local database.
