You can use broadcast messages to display information on all pages of the gitlab web UI. You must have administration permissions to manipulate broadcast messages.

• v4 API:
  • :class:`gitlab.v4.objects.BroadcastMessage`
  • :class:`gitlab.v4.objects.BroadcastMessageManager`
  • :attr:`gitlab.Gitlab.broadcastmessages`
• GitLab API: https://docs.gitlab.com/ce/api/broadcast_messages.html

List the messages:

msgs = gl.broadcastmessages.list()

Get a single message:

msg = gl.broadcastmessages.get(msg_id)

Create a message:

msg = gl.broadcastmessages.create({'message': 'Important information'})

The date format for the starts_at and ends_at parameters is YYYY-MM-ddThh:mm:ssZ.

Update a message:

msg.font = '#444444'
msg.color = '#999999'
msg.save()

Delete a message:

gl.broadcastmessages.delete(msg_id)
# or
msg.delete()
