Thanks to the tools of topological strings and the AGT-W relation, we can attack the problem of obtaining the 3-point functions of Toda CFT. We calculate the superconformal index of the 5D T_N theories suggest that it should be interpreted as the three-point structure constants of q-deformed Toda. After careful rewriting, we show how to obtain the undeformed Toda correlation functions as well. Our formula, has the correct symmetry properties and reproduces the known results of Fateev and Litvinov.
