In this talk, I will firstly review the hexagonalization approach for computing correlation functions. Then the calculation of a five-point function which requires the two-particle contribution will be explained. Using the building blocks introduced for the two-particle case, I will describe how to construct the multi-particle integrand which is useful for higher-loops and non-planar calculations. In the last part of the talk, I will comment on how to perform the integrals and list a few open questions.
