Abstract: Holographic currents and their associated Ward identities are derived in the framework of gravity/gauge duality. Holographic improvements of the energy-momentum tensor and $R$-symmetry current which are consistent with the Ward identities are displayed. The effects of specific string loop corrections to the bulk action are included as four derivative effective Lagrangian terms and their contributions to the trace and $R$-symmetry anomalies of the boundary theory are determined. As an example, the construction is applied to the $\mathcal{N}=2$ conformal supergravity which is taken to be dual to a boundary $SU(N)\ifmmode\times\else\texttimes\fi{}SU(N)$, $\mathcal{N}=1$ superconformal field theory.
