Getting error in testing facebook business-sdk

Question

I started with facebook business sdk for php. Was following this doc: https://developers.facebook.com/docs/business-sdk/getting-started/ installed without trouble, then tried testing as they instructed, created src/test.php

<?php
require_once __DIR__ . '/../vendor/autoload.php';
use FacebookAds\Api;
use FacebookAds\Logger\CurlLogger;
use FacebookAds\Object\AdAccount;
use FacebookAds\Object\Campaign;
use FacebookAds\Object\Fields\CampaignFields;

$app_id = "{app-id}";
$app_secret = "{appsecret}";
$access_token = "{access-token}";
$account_id = "act_{{adaccount-id}}";

Api::init($app_id, $app_secret, $access_token);

$account = new AdAccount($account_id);
$cursor = $account->getCampaigns();

// Loop over objects
foreach ($cursor as $campaign) {
  echo $campaign->{CampaignFields::NAME}.PHP_EOL;
}

filled in the required values. and ran the file. Getting this:

FacebookAds\CrashReporter : Enabled
FacebookAds\CrashReporter : Exception detected!

Not sure what I am doing wrong. Didnt find much by searching. Can anyone please help?

Answer 1

The error you get is pretty explicit: "Invalid OAuth access token" you can check the token you supplied using Facebook's token-debbuger @ https://developers.facebook.com/tools/debug/accesstoken/

most probably you are missing the "ads_management" permission.
