Integrable structure of the symmetry reduced dynamics of massless bosonic sector of the heterotic string effective action is presented. For string background equations that govern in the space-time of D dimensions (D{>=}4), the dynamics of interacting gravitational, dilaton, antisymmetric tensor and any number n{>=}0 of Abelian vector gauge fields, all depending only on two coordinates, we construct an equivalent (2d+n)x(2d+n)-matrix spectral problem (d=D-2). This spectral problem provides the base for the development of various solution constructing procedures (dressing transformations, integral equation methods). For the case of the absence of Abelian gauge fields, we present the soliton generating transformations of any background with interacting gravitational, dilaton, and the second rank antisymmetric tensor fields.
