Portal version: 0.1.0
Updated: 2026-08-28
Source menu item: Event destinations
Availability: Documented and testable

The source contract and local workflow exist. Access still depends on the target hospital deployment and its policy gates.

FHIR subscriptions and HMAC-signed webhook delivery are the partner event destination contract.

What you can use now

• Verify raw bodies, timestamp windows, delivery IDs, event types, and HMAC signatures before parsing.
• Persist delivery IDs transactionally with side effects to prevent replay.

Current limits

• Queue-row transition topics are not a supported external event family.

Next step

Start with the medOS Developer overview and confirm the target hospital’s enabled contracts before production work.
