Post Intake Automation

The patient submitted their intake form — now what? This page covers the patterns for triggering intake processing and the workflows that follow once intake data has been ingested into FHIR resources.

Server-Scoped Subscriptions

A server-scoped Subscription fires for rest-hook changes across every project on the server, not just its own project. It's useful for project-per-tenant deployments that need one central, server-wide data-processing flow.

Subscription Extensions

Subscriptions

Subscriptions are event-driven notifications, like webhooks, and are commonly used for integrations and automations. Medplum supports subscribing to changes on FHIR resources. There is a description FHIR Subscriptions on HL7.org that describes the functionality in detail.
