Edit a Backend

You can edit any backend that you've added, and for the backends that were automatically added to your visual application upon its creation, you can override their configurations set at the tenant level for your Visual Builder instance.

When you override a provided backend's configuration, you are essentially adding a backend with the same ID from the environment catalog to the application catalog and customizing some detail (for example, the authentication method specified for a backend server) just for that particular application.

To edit and customize a backend service:

  1. Open the Backends tab from the Services tab in the Navigator.
  2. Select the backend you want to modify, then click the Servers tab.

    Tip:

    Click the View Information icon (View Information icon) to view backend details, such as server and authentication inherited from your Visual Builder instance's tenant-level settings.
  3. To edit an Oracle cloud services backend, you'll need to click Override Backend to modify the settings specified by your administrator:
    This image shows the details of a selected backend. You can click the different tabs (Overview, Servers, Headers, and Source) to view details. The Servers tab (selected in the image) shows the List of Servers inherited from the Tenant Settings, with options to View Information, Copy, and Delete. An Override Backend button is also shown.

  4. Edit the backend service's details as required:
    • Use the Overview tab to change the description, if desired, or to change the transforms attached to the backend (see Add Transforms for more information).

    • Use the Servers tab to add a new server that hosts the backend service, or modify an existing server. In both cases, a dialog appears where you can identify the server, specify an application profile that will use the server, add headers, and configure security options. These options are the same as those you configure when you define a service connection.

    • Use the Headers tab to add static headers.

      Under Custom Headers, you can add headers that are passed from the browser to the service (for example, a REST-Framework-Version header). Under Secure Headers, you can add headers that are inserted only at the server end (for example, a credential that you never want to be available on the browser).

    • Use the Source tab to view the contents of the services/catalog.json at the application level, and to edit the file if needed.

      You can also access this file under services in the Navigator's Source View tab.
