Error (405) Method Not Allowed when using POST - php

Question

I am using Laravel 5.4 with JWTAuth & Dingo and for some reason I am now no longer able to make POST requests with Postman. This was working when I first set it up, but not I get the response 405 Method Not Allowed
This seems to have been raised a few times on here, but I can't seem to find a solution. I've cleared the route cache, and when i do api:routes the correct routes are in there.
Below is the routes file, and the controllers it should be sending too. I am only having the issue with the LeadController routes.
api.php
use Dingo\Api\Routing\Router;
/** #var Router $api */
$api = app(Router::class);
$api->version('v1', function (Router $api) {
$api->group(['prefix' => 'auth'], function(Router $api) {
//$api->post('signup', 'App\\Api\\V1\\Controllers\\SignUpController#signUp');
$api->post('login', 'App\\Api\\V1\\Controllers\\LoginController#login');
$api->post('recovery', 'App\\Api\\V1\\Controllers\\ForgotPasswordController#sendResetEmail');
$api->post('reset', 'App\\Api\\V1\\Controllers\\ResetPasswordController#resetPassword');
});
$api->group(['middleware' => 'jwt.auth'], function(Router $api) {
$api->get('protected', function() {
return response()->json([
'message' => 'Access to protected resources granted! You are seeing this text as you provided the token correctly.'
]);
});
$api->get('refresh', [
'middleware' => 'jwt.refresh',
function() {
return response()->json([
'message' => 'By accessing this endpoint, you can refresh your access token at each request. Check out this response headers!'
]);
}
]);
$api->post('lead/store', 'App\\Api\\V1\\Controllers\\LeadController#store');
$api->get('lead', 'App\\Api\\V1\\Controllers\\LeadController#index');
});
});
LeadController.php
namespace App\Api\V1\Controllers;
use Symfony\Component\HttpKernel\Exception\HttpException;
use Tymon\JWTAuth\JWTAuth;
use App\Http\Controllers\Controller;
use Dingo\Api\Routing\Helpers;
use Illuminate\Http\Request;
use Carbon\Carbon;
use App\Lead;
use App\User;
class LeadController extends Controller
{
use Helpers;
public function index(Lead $leads)
{
$leads = $leads->all();
$count = 0;
foreach($leads as $key => $lead){
$user = User::where('id', $lead->user_id)->first();
$leads[$count]['name'] = $user->name;
array_pull($leads[$count], 'user_id');
$count++;
}
return $leads;
}
public function store(Request $request)
{
$today = new Carbon();
$this->validate(request(), [
'owner' => 'required',
'bname' => 'required|min:3|max:255',
'tname' => 'max:255',
'created' => 'required|date|before_or_equal:today',
'update' => 'date'
]);
if(!$user = User::where('zoho_id', $request->get('owner'))->first())
return $this->response->error('invalid_owner', 500);
$lead = new Lead;
$lead->user_id = $user->id;
$lead->bname = $request->get('bname');
$lead->tname = $request->get('tname');
$lead->created_at = $request->get('created');
$lead->updated_at = $request->get('updated');
if($lead->save())
return $this->response->created();
else
return $this->response->error('could_not_create_lead', 500);
}
}

I found the answer, for this whilst I almost finished writing the question by stumbling upon the answer here:
https://laracasts.com/discuss/channels/laravel/dingo-api-and-postman-not-matching-post-request
Remove the trailing / from the request URL. So will leave this answer here, in the hopes it may prove useful to someone.
ie. http://api.someurl.app/api/lead/store?token=....
Perhaps, someone can suggest a way of allowing trailing / ??
