My talk is a pedagogical introduction to the integrable aspects of the AdS/CFT duality. I will start by motivating the holographic duality both on the gauge and the string theory side. Integrability will be exploited via the bootstrap program, which aims to solve integrable models completely by determining the scattering matrix of the particles and the form factors of local operators. These infinite volume quantities then can be used to build the full spectrum and correlation functions at any finite size. In the talk I will explain the adaptation of the form factor bootstrap program to calculate the 3pt functions of N=4 SYM theory and the lightcone string field theory vertex of AdS5xS5.
