You can use http_response_code()
to set HTTP response code.
If you pass no parameters then http_response_code will get the current status code. If you pass a parameter it will set the response code.
http_response_code(201); // Set response status code to 201
For Laravel(Reference from: https://stackoverflow.com/a/14717895/2025923):
return Response::json([
'hello' => $value
], 201); // Status code here
