Abstract: In the first part of the talk I will briefly explain how integrability has been used to determine the spectrum of the anomalous dimensions of the N=4 SYM theory in the planar limit. The integrability methods are not restricted to the spectrum, in particular they can be used the determine the correlation functions, at least in some limits.

In the second part of the talk I will explain how to formulate the problem of computing the three-point function of operators with determined R-charges in the language of integrable spin chains. I will explain the results of I. Kostov for the large R-charge limit of the tree-level 3 point function in the su(2) sector, as well as results at one loop for these operators, obtained in collaboration with I. Kostov, F. Loebbert and D. Serban. I will briefly comment on the comparison of these results with those obtained from the string side.
