Basic Mode

Only users under the same account as the topic creator have the permissions to publish messages through the topic. Using topic policies, you can specify which users and cloud services can perform which topic operations, for example, querying topic details and publishing messages. Topic creators always have permissions over a topic even if they grant topic permissions to other users.

Configuring Topic Policies in Basic Mode

  1. Select Simple Message Notification under Application.

    The SMN console is displayed.

  2. In the navigation pane, choose Topics.

    The Topics page is displayed.

  3. Locate a topic, click More under Operation, and select Configure Topic Policy.
  4. In the Configure Topic Policy dialog box, configure the topic policy in basic mode.

    The basic mode simply specifies which users or cloud services have permissions to publish messages to the topic. For details, see Table 1.
