# Update Hermes messaging settings

Review and modify the current the Hermes configuration properties to control Apache Kafka integration, topic management, and other messaging behavior.

## Before you begin

Role required: maint or hermes\_admin

## Procedure

1.  Navigate to **All** > **Hermes Messaging Service** > **Settings**.

    The Hermes Settings page is displayed.

2.  Locate the category for the property that you plan to modify, such as **Kafka Integration** or **Topic Management**.

    Each category displays a table of properties with property name, value, valid range, and description columns.

3.  Review the current value and valid range for the property.

4.  Change the value by entering a new value in the **Value** field.

    Verify that the value is within the range shown in the **Valid Range** column.

    -   Boolean properties use a list with true or false options.
    -   Topic Inspector format properties use a list with string or binary options.
5.  Select **Save Changes**.

    -   If the value was accepted and applied, the message `Properties saved successfully` is displayed.
    -   If the value exceeds the valid range or is invalid, the message `Some properties could not be saved. Invalid values for the following properties` is displayed. Correct the value and save your changes again.
