Retrieve rows from a Synchronized DE through SOAP API using Access Token from REST API

Question

I'm trying to retrieve rows from a Synchronized DE using the SOAP API with the REST API Access Token:

I've seen this: Cannot retrieve fields from a Shared Data Extension using the SOAP API

And this: http://www.kellyjandrews.com/2014/02/20/using-fuel-oauth-with-the-soap-api.html

I am able to retrieve a Data Extension Object and Folders, but no rows from a DE.

Here's my request:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <soapenv:Header>
      <fueloauth xmlns="http://exacttarget.com">{{Access Token}}</fueloauth>
  </soapenv:Header>
   <soapenv:Body>
      <RetrieveRequestMsg xmlns="http://exacttarget.com/wsdl/partnerAPI">
         <RetrieveRequest>
            <ObjectType>DataExtensionObject[Contact_Salesforce]</ObjectType>
            <Properties>Email</Properties>
         </RetrieveRequest>
      </RetrieveRequestMsg>
   </soapenv:Body>
</soapenv:Envelope>

I get this error: Error: API Permission Failed.

I'm wondering if it could have something to do with the Package/API Integration that was set-up.

Answer 1

Weird. In the API Integration permission settings, I had to set Read and Write Permissions for Data Extensions in order to do a Retrieve on a Data Extension.
