  title: Medplum Deploy Bot
  summary: Create a Bot resource, then create a Subscription that invokes the Bot on resource changes.
  description: >-
    Medplum Bots are serverless functions stored as FHIR Bot resources and wired
    to events through FHIR Subscriptions. This workflow creates a Bot resource,
    captures its id, then creates a Subscription whose channel targets the Bot so
    that matching resource changes trigger it, and finally reads the Subscription
    back to confirm it is active. Every step spells out its FHIR request inline.
    Medplum Bot deployment and execution use proprietary $deploy and $execute
    operations that are not declared in this OpenAPI description, so this flow
    wires the Bot to an event source via Subscription instead and notes that
    adaptation.
