      Read and write a single user's notification preferences, per topic and per
      channel.
  - name: Messages
    description: >-
      Look up the messages Courier has accepted, inspect their delivery history
      and rendered output, and cancel, resend, or archive them.

    description: >-

      and the embedded designer — can call Courier as a single user. Server-side
      requests authenticate with your workspace API key instead.
