When you have developed a custom notification gateway, you need to register the gateway in the system:

1. Open the **Notifications** application.
2. Click **New gateway** on the **Gateways** tab.
3. Enter the following details into the **New gateway** form:
   - **Display name** - name used for the gateway in the administration interface.
   - **Code name** - serves as an identifier for the gateway. Leave the default _(automatic)_ value to generate an appropriate code name based on the display name.
   - **Description** - text describing the gateway.
   - **Enabled** - if unchecked, the notification gateway is not functional — this can be useful if you want to temporarily disable the gateway so that no messages are sent, e.g. when you are performing administration tasks.
   - **Gateway provider - Assembly name** - identifies the assembly where the gateway class is stored. Select _(custom classes)_ for classes created in the App\_Code folder.
   - **Gateway provider - Class** - name of the class containing the gateway code, including namespaces.
   - **Supports message subject** - enable if the gateway's message format supports message subjects.
   - **Supports HTML text** - enable if the gateway supports messages in HTML format (e.g. for e-mails).
   - **Supports plain text** - enable if the gateway supports plain text format (e.g. for SMS).
4. Click **Save** to confirm the changes.
