We provide a model-independent dynamical proof for the consistency relation of 3-point correlation functions from the Hamiltonian and field redefinition. This relation can be applied to single field inflation, multi-field inflation and the curvaton scenario. This relation can also be generalized to $n$-point correlation functions up to arbitrary order in perturbation theory and with arbitrary number of loops.18 pages. v2 and v3: references addedHigh Energy Physics - TheoryAstrophysicsGeneral Relativity and Quantum Cosmologytext
