title: Can I use test token in Stripe Connect to create test charge?
body: <p>My PHP application is using Stripe. People sell their products on my platform and I'm getting my fee from it. I already have a link that makes it possible for users to connect their Stripe accounts to my platform. I get authentication code and then I use it to get access token. The response is as follows (replaced long random strings with abcd):</p>
  
  <pre><code>{
    "token_type": "bearer",
    "stripe_publishable_key": "pk_test_abcd",
    "scope": "read_write",
    "livemode": false,
    "stripe_user_id": "acct_abcd",
    "refresh_token": "rt_abcd",
    "access_token": "sk_test_abcd"
  }
  </code></pre>
  
  <p>Then, I'm trying to create a test charge for a connected account:</p>
  
  <pre><code>$charge = Stripe\Charge::create([
      'amount'   =&gt; 1000,
      'currency' =&gt; 'usd',
      'source'   =&gt; 'sk_test_abcd',
  ], ['stripe_account' =&gt; 'acct_abcd']);
  </code></pre>
  
  <p>But I'm getting the following error:</p>
  
  <blockquote>
    <p>No such token: sk_test_abcd</p>
  </blockquote>
  
  <p>What am I doing wrong?</p>
