I think Redux middleware is the answer to this. My preferred approach is to keep all my actions as simple serializable objects, and have (potentially many) small middlewares that listen for certain action types and perform async tasks and dispatch further simple action objects. There are also more fully-baked middlewares like Redux Saga, but I find that those are a bit too heavy-handed and result in too much “lock-in” for implementing your actions and action creators.
