## Consuming Webhooks

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.

## Messaging Automations

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).
