Google Contacts API vs People API
<p>I'm having a problem with the 2 APIs above. Given the next scenario: I have 2 different google accounts. One that doesn't use Google+ and a second account that uses Google+ </p>

<p>When using Contacts API on the first account that doesn't use Google+ I can see all my contacts:</p>

<pre><code>GET /m8/feeds/contacts/&lt;email&gt;/full
</code></pre>

<p>Same for the second account that uses Google+.</p>

<p>When I'm using People API for the first account that doesn't use Google+, I'm getting an empty response (actually I'm getting just the next sync token:</p>

<pre><code>GET https://people.googleapis.com/v1/people/me/connections
</code></pre>

<p>With the next scope:</p>

<pre><code>https://www.googleapis.com/auth/contacts
</code></pre>

<p>Returns: </p>

<pre><code>{
  "nextSyncToken": "CMe6...."
}
</code></pre>

<p>The same call for the second account (with Google+) works like a charm</p>

<p>The only difference between the 2 accounts is Google+, is it possible that People API only works for accounts with Google+? Or is it something else that I'm missing</p>
