NDIS API — overview

Navigator connects to the NDIS through two APIs — PRODA (the older system) and PACE (the newer one). Both pass through a single gateway inside Navigator. This article explains which API does what, and which events and flows come from each.

The two NDIS APIs

The NDIS operates two provider-facing APIs:

Navigator talks to both APIs through a single internal gateway (the Paradox integration). You don't choose which API to use for a given operation — Navigator picks the right one based on the operation and the participant's plan type. For your team, the two APIs look like one system.

What this article gives you: a clear picture of which API does what, so when a task or note mentions "PACE" or "PRODA", you know where the data came from.

Capability matrix — what each API does

CapabilityPRODAPACE
Syncing funds and budgetsYesYes
Retrieving participant plansYesYes
Submitting claims (payment requests)YesYes
Remittance advice (payment status)YesYes
Service bookingsYesYes
Plan manager relationship events (new / ended)Yes
Plan approval notificationsYes
Budget updated notificationsYes
Plan variation / extension / renewal eventsYes

The short version: PRODA handles the transactional side (claims and fund queries) and PACE adds the event-driven side (automatic notifications when something about the participant's plan or plan management relationship changes).

NDIS events Navigator listens for

PACE sends Navigator webhook notifications when certain things happen on a participant's plan. Each event triggers a specific workflow.
