We review recent progress in understanding the exact scattering theory for the massive sector of strings propagating on AdS_3 backgrounds. The role of Yangians will be highlighted, with particular emphasis on the new features displayed by this case when compared to the AdS_5 background, and the issues of massless modes in the theory will be discussed upon.
