Many SaaS products including popular services like Stripe and Okta support Webhooks, allowing a web application to register a Medplum URL to receive notifications. When a certain event occurs in the source application, such as a new user signup or a change to a record, the source application sends an HTTP POST request to the URL registered by the destination application. This HTTP POST request contains information about the event that occurred.
These patterns show how to bridge Medplum messaging to external channels (SMS, email, push notifications) using Bots and on-demand $execute. For in-platform automations (Tasks, reminders, scheduling), see Messaging Automations.
Overview of Medplum Bots
The patterns on this page use Medplum Bots — an advanced feature that is disabled by default on many projects — and FHIR Subscriptions. Recurring automations also use cron-scheduled Bots (Cron Jobs for Bots). Confirm Bots are enabled for your project and that you can create Bots and Subscriptions (typically as a Project administrator).
