Latest news and guidance

API Synchronising Delay

As a result of the significant volume of changes being pushed to the ODS API we have experienced a delay in updating this data.

Users utilising the last change date feature of the API should temporarily synchronise their data using (date of processing – 2 days) as their last change date and should do so until conclusion of the reconfiguration activities (mid-April).

Following conclusion of these activities, ODS recommend that you refresh data using the last change date of 2020-04-01 to be certain that your systems are fully synchronised with ODS data.

Issue resolved: The reconfiguration activities are now complete and the API is fully synchronised. Users making use of the sync endpoint should carry out a one-off synchronisation using a last change date of 2020-04-01 before commencing a standard daily update routine using (date of processing -1 day).
