Accredited Programmes and Delius

An integration service to enable the Accredited Programmes in Community service to exchange data with Delius, supporting the replacement of the IAPS (Integrated Accredited Programme System) and IM (Interventions Manager) systems.

Business Need

The Accredited Programmes service needs to:

Display probation case information
Create and manage programme appointments in Delius
Log status changes and important events to the Delius contact log

This service acts as the integration layer between the Accredited Programmes service and Delius, providing synchronous APIs for probation case information and appointment management along with asynchronous consumption of domain events for status changes.

Status Changes

Accredited Programmes updates the status for the person on a programme (e.g. “on programme”, “programme completed”, “ withdrawn”).
The integration service adds a contact to Delius to inform the offender’s practitioner of the status change.

Business Event	HMPPS Domain Event
Status change	`accredited-programmes-community.referral.status-updated`

Example messages are in the development source tree.

Appointments

Programme attendance appointments and 3‑way meetings are created or updated in bulk by Accredited Programmes.
Delius contacts are updated and linked to the Accredited Programmes session records via external reference.
