MailChimp API DrewM\MailChimp\MailChimp::call() call to undefined method - php

Question

I am trying to validate apikey but I am stuck on this issue if a user enters a apikey it should be validated from MailChimp account and should show a message of in-valid key if api key is not matched with MailChimp.
My Code:
public function authenticateApiKey(Request $request)
{
$fieldsValidation = [
'api_key' => 'required|unique:apikey,api_key',
];
$validator = Validator::make($request->all(), $fieldsValidation);
if ($validator->fails()) {
$resultArray = [
'status' => 0,
'message' => $validator->errors()->first(),
'dataArray' => []
];
} else {
$api = new APIKEY($request->all());
$mc = new MailChimp($api);
$mailchimp_ping = ($mc->call('helper/ping'));
if(!$mailchimp_ping){
}
$request->user()->apikey()->save($api);
$resultArray = ['status' => 1, 'message' => 'Mailchimp Api key added into system successfully!', 'dataArray' => $api];
}
return \Illuminate\Support\Facades\Response::json($resultArray, 200);
}
When I hit this call it said call to aundefined method is there any other in which I can validate apikey.
Any help would be appreciated!

} else {
$api = new APIKEY($request->all());
$mc = new MailChimp($api);
$mailchimp_ping = $mc->get('/ping');
if ($mailchimp_ping["status"] == 401) {
return redirect()->back()->with("errorMessage","api key is invalid")->withInput(Input::all());
}
///do here if api key is valid
$request->user()->apikey()->save($api);
$resultArray = ['status' => 1, 'message' => 'Mailchimp Api key added into system successfully!', 'dataArray' => $api];
// }
return \Illuminate\Support\Facades\Response::json($resultArray, 200);
}
}

Make a request. If the request works, the key is valid. Follow this link to make a ping request. It's a health check endpoint for MailChimp API 3.0.
$mailchimp_ping = $mc->get('/ping');
dd($mailchimp_ping);
Here is your requested full controller that works fine-
<?php
namespace App\Http\Controllers;
use App\APIKEY;
use DrewM\MailChimp\MailChimp;
use Illuminate\Auth\Access\Response;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Mail;
use Illuminate\Support\Facades\Validator;
class ApiController extends Controller
{
public function authenticateApiKey(Request $request)
{
$fieldsValidation = [
'api_key' => 'required|unique:apikey,api_key',
];
$validator = Validator::make($request->all(), $fieldsValidation);
if ($validator->fails()) {
$resultArray = [
'status' => 0,
'message' => $validator->errors()->first(),
'dataArray' => []
];
} else {
$mc = new MailChimp($request->input('api_key'));
$mailchimp_ping = $mc->get('/ping');
if ($mailchimp_ping["status"] != 401) {
$api = new APIKEY($request->all());
$request->user()->apikey()->save($api);
$resultArray = ['status' => 1, 'message' => 'Mailchimp Api key added into system successfully!', 'dataArray' => $api];
return \Illuminate\Support\Facades\Response::json($resultArray, 200);
}
$errorResponse = [
'message' => 'Not valid api key!',
'code' => '401'
];
return $this->apiResponse('error', '401', $errorResponse);
}
}
}
