  We study Feynman integrals in the framework of Gel'fand-Kapranov-Zelevinsky
(GKZ) hypergeometric systems. The latter defines a class of functions wherein
Feynman integrals arise as special cases, for any number of loops and kinematic
scales. Utilizing the GKZ system and its relation to $D$-module theory, we
propose a novel method for obtaining differential equations for master
integrals. This note is based on the longer manuscript arXiv:2204.12983.
