title: How to use "get user information" PayPal API?
body: <p>In order to use the <a href="https://developer.paypal.com/docs/api/#get-user-information" rel="nofollow">get user information</a> API, I have to pass the authorization bearer.  I can use this to get the bearer for my account:</p>
  
  <pre><code>curl -v https://api.sandbox.paypal.com/v1/oauth2/token \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "{Client-Id}:{Secret}" \
  -d "grant_type=client_credentials"
  </code></pre>
  
  <p>But what would I do for another user?</p>
