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. Log in to the management console.
  2. In the upper left corner of the page, click and select the desired region and project.
  3. Click . Select Simple Message Notification under Management & Governance.

    The SMN console is displayed.

  4. In the navigation pane, choose Topic Management > Topics.

    The Topics page is displayed.

  5. Locate a topic, click More under Operation, and select Configure Topic Policy.

    Alternatively, click a topic name. In the upper right corner of the displayed page, click Configure Topic Policy.

  6. 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.
