I dont know if this possible, but is possible to have multiple versions of Dingo API so for example:
I can use:
api.example.com/v1/request
api.example.com/v2/request
api.example.com/v3/request
and still be able to search via the web browser
Edit:
Try creating a middleware to try to set the setting depending on the request. Like this:
$request_url = $request->getRequestUri();
$request_url = explode("/", $request_url);
$current_version = array_filter($request_url);
Config::set('api.version', $current_version[1]);
But still nothing, any one has an idea?
