Don't make the mistake to mixup too many technologies in an early stage of your application. Maybe the ReactQL stack offers too many libraries?
The question is not how to combine Redux and Apollo Client to make remote API request, but how to separate them for their specific responsibilities. When you are using Apollo Client in your client application, because you have a GraphQL backend, then use Apollo for your remote state. Then Redux (or MobX/React's Local State) is only used for the view state (e.g. popup toggle, search field). If you are not using Apollo Client, Redux (with redux-saga or redux-thunk) can be used for the remote data instead. Otherwise, use the Query and Mutation components provided by react-apollo to connect your remote data to your React layer.
If your application is purely remote data driven and uses a GraphQL backend, Apollo Client can be sufficient for your application.
If you have a few view states in your application, mix in React's local state management.
If you have several to a lot of view states, use Redux or MobX for your view state or try out apollo-link-state.
