The integration of Internet of Things (IoT) technology to achieve supply chain integration (SCI) has been considered as a hot topic in recent years. Through a systematic literature review in the context of supply chain management, this article aims to review IoT and its role in achieving SCI, as well as to provide new directions for future research. The principal objective of this article is to categorize scholarly articles that examine the utilization of IoT in the supply chain to achieve SCI in different sectors. The selection and refinement process identified a total of 133 articles. After removing duplicates and after the screening stage, the number reached 35 studies. These 35 studies were analyzed by introduction, primary results, and conclusions in the assessment stage. Finally, of those 35 studies, 26 were selected to be thoroughly examined for this review of the literature. The literature underscores the pivotal role of Internet technology in achieving SCI and finds solutions based on different industry sectors with appropriate research questions.
