Summary: The aim of this paper is to generalize Caristi's fixed point theorem in a $K$-complete quasi-metric space endowed with a reflexive digraph by using Száz maximum principle [\textit{Á. Száz}, Math. Commun. 12, No. 2, 155--161 (2007; Zbl 1143.06002)]. An example is given to support our main result.
