putting if statement in api with laravel - json

Question

I'm currently learning on how API works and my mentor gave me a task to create submit the form using API and store the data on database with laravel and the task also require mandatory if logic on some field.
I have succeeded with the first task (storing data to the database ) and I'm having difficulties writing the mandatory if.
I'm confused, on my task paper I'm told to create one controller, one model and two endpoints (request-schedule and request-leaving) where each endpoint should have some parameters.
and for the request-leaving parameter, there are 10 parameters, 6 of them have this requirement like (mandatory if request type Request Day Off)
There are 3 requests typewritten on there
1. Request Day off
2. Request Schedule
3. Change Schedule
I'm a super newbie in programming, does anyone know how to solve this?
public function CreateReqSchedule(Request $request)
{
$reqschedule = new B777();
$reqschedule->reqtype = $request->input('reqtype');
$reqschedule->startdate = $request->input('startdate');
$reqschedule->enddate = $request->input('enddate');
$reqschedule->reason = $request->input('reason');
$reqschedule->route = $request->input('route');
$reqschedule->actualschedule = $request->input('actualschedule');
$reqschedule->changetoschedule = $request->input('changetoschedule');
$reqschedule->swapcrewid = $request->input('swapcrewid');
$reqschedule->swapcrewschedule = $request->input('swapcrewschedule');
$reqschedule->note = $request->input('note');
$reqschedule->save();
return response()->json($reqschedule);
}
code above is my only work, I'm feeling anxious, because I've googled it myself but I'm still stuck.

So you are talking about validations. you can put laravel validation into it like below
Use required validation for mandotory data and return response in json
// Making validation for fields
$validator = \Validator::make($request->all(), [
'fields1' => 'required',
'fields2' => 'required',
'fields3' => 'required',
]);
if ($validator->fails())
{
// return response on validaton fails
return response()->json(['status'=>400,'errors'=>$validator->errors()->all()]);
}
// If validation passes store your data in database
