Redux example action using a concrete API (injected as paramter to be mocked in testing).

postAuthorizationAction.js

export function postAuthorization(email, password, Api = AuthenticationApi) {
  return (dispatch) => {
    return Api.postAuthorization(email, password).then(
      (response) => {
        const token = response.data.token;
        localStorage.setItem(`TeamReaderApp_${process.env.NODE_ENV}_token`, token);

        dispatch(createSession(token));
        dispatch(setLinks({ collection: response.data.links }));
        dispatch(loadCategories());
        return response;
      },
      (error) => {
        dispatch({
          type: CREATE_SESSION,
          payload: error,
          error: true
        });
        throw error;
      }
    );
  };
};
