This is making requests to an endpoint repeatedly. To do it efficiently, which means to get only new or updated records, use the Filter on the Version property in a query.

  • For a given endpoint, the Version property may be considered as a data set timestamp.
  • New or updated data records get the new highest value in the Version property.
  • To get the new data, query for all the records with a greater Version value than the previous one.


If you got the data from odata/Clubs and the maximum Version value within data records you got is Y.

The new data of Clubs you can get with the query: /odata/Clubs?$filter=version gt Y


This is creating a subscription to a desired Event in the system to get notifications and data related to that Event.
