A bit late response, but I'm sure others would like to know the same. I managed to make it work with a bit of customization. In my add-on for using Azure resourcegraph endpoint i wanted the global account to have the following: Client ID (Instead of Account Name) Client Secret (Instead of password) Tenant ID (New additional field) How-to: Navigate to /SplunkHome/etc/apps/<app-name>/appserver/static/js/build/ Edit your globalConfg.json Add your desired custom field in the "header" under the list of "tabs". This will make your new field show in the UI after it's been added Next, add your new field in the "entity" list. Unless you require a specific validator, I would just copy paste an existing field and edit it to your purpose. As shown in the image, I've altered username to Client ID and also added my Tenant ID field   Next step is to configure the handler to accept the new input field. Navigate to your app's bin folder and open <appname>_rh_account.py  Add your new custom field as an object in the "fields" list. Copy paste an existing one to make it easier for you if possible Finally, to update your app with your new custom inputs, you must navigate to the addon builder app. Open your list of apps, then click properties. Increment your version number. This should update your apps UI.  Hope this helps.   ... View more
