  The form of higher-spin current interactions in $AdS_4$ is derived from the
full nonlinear higher-spin equations in the sector of Weyl 0-forms. The
coupling constant in front of spin-one currents built from scalars and spinors
as well as Yukawa coupling are determined explicitly. Couplings of all other
higher-spin current interactions are determined implicitly. All couplings are
shown to be independent of the phase parameter of the nonlinear higher-spin
theory. The proper holographic dependence of the vertex on the higher-spin
phase parameter is shown to result from the boundary conditions on the bulk
fields.
