The admin UI allows adding HTTP headers for the Statuspal requests. However, the HTTP headers are restricted to a predefined list of headers, and it makes it impossible to add a custom header via the admin UI. If a custom HTTP header is added via the Statuspal API, the new header shows up in the admin UI. However, the UI renders the form field empty for the key, but with the intended value for the value field. Please see the screenshot. If the admin UI form is saved, the custom HTTP header added via API will likely to be reset or removed altogether, simply because the header name is not listed in the pre-defined list. Please allow adding custom HTTP headers using the admin UI.
