API – Get All Customers from Magento Using REST API

I think that to work out if you are on the last page or not, you have to find out how many records there are in Magento then calculate how many pages there are depending on your page filter.

As far as I am aware (from looking at the REST documentation), there are no REST methods to return this in the API so you'll have to extend it on to add this to the REST API. I did something similar ages ago as an investigation into extending the Magento products REST API. I did this by implementing a whole new REST route so more of a separate custom API not directly related to the normal Magento catalog API. You could either follow this route and create a new custom Customer API or rewrite the existing API models to add this extra call in.

Details of how I approached it can be found at http://magepim.com/news/Extending-the-Magento-REST-API-part-1_13

Thanks to the help of SoapUI, I found the following request format would work using PHP SoapClient:

   $request = [ 
        'sessionId' => $session,
        'filters'   => [
          'filter' => [
            [   
              'key'   => 'status',
              'value' => 'pending'
            ]   
          ]   
        ]   
    ];

XML Request:

<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope" xmlns:ns1="urn:Magento">

    <ns1:salesOrderListRequestParam>

        </filter>
      </filters>
