Online Development Application Service API V2

Online DA Data API

Created 07/06/2025

Updated 07/06/2025

The outbound API enables a council to receive the DA data entered by an applicant into the Online DA Service directly into their IT system in real-time. This eliminates the need for double entry of application details into the council IT system.

Councils can then progress the application in their own IT system (conduct completeness checks, request and receive additional information and provide a determination) as the inbound API transfers this data from council to the Online DA Service.
