  In this manuscript, we determine the optimal approximation rate for Skorohod
integrals of sufficiently regular integrands. This generalizes the optimal
approximation results for It\^o integrals. However, without adaptedness and the
It\^o isometry, new proof techniques are required. The main tools are a
characterization via S-transform and a reformulation of the Wiener chaos
decomposition in terms of Wick-analytic functionals.
