The APIs are built using RESTful principles (Representational State Transfer) which makes it easy to retrieve updates to the information.
The APIs complement the XML ORD products available through the NHS Digital Terminology Reference data Update Distribution service (TRUD). The published standard Health and Social Care Organisation Reference Data (DCB0090) approved by the Data Co-ordination Board (DCB) has been amended to direct consumers towards the ORD API.
Users can choose which of the two APIs best supports the standards they have in place and the goals of their service, the ORD compatible API or the FHIR compatible API, or can use both. The ORD compatible API contains the full record from ODS, and the FHIR compatible API contains a reduced dataset, most useful for helping with transactions.
