Abstract. We review certain results for amplitudes of spectral flowed operators in string theory on AdS3. We present the modified Knizhnik-Zamolodchikov and null vector equations to be satisfied by correlators including w = 1 operators. We then discuss the three point function of two w = 1 and one w = 0 operators in the x-basis, and perform a consistency check on the definition of the w = 1 operator. We finally exhibit the steps in the calculation of the winding conserving four point functions for operators in arbitrary spectral flowed sectors, both in the mand x-basis, under the only assumption that at least one of the operators is in the spectral flowed image of the highest weight discrete representation.
