Abstract Background: The increasing penetration of smartphones and the Internet in developing countries caused the rise of e-retail. Conversational commerce is highly increasing via interaction through messengers. To extract the benefits of both trends, companies have adopted messenger chatbots. These chatbots use Artificial intelligence and natural language processing to give live responses to the customer and assist online shopping on the messenger interface. This research aims to discover the factors that affect the use of messenger chatbots and their influence on attitude and behavior intention. Methods: The research methodology includes the Technology Acceptance Model (TAM) with the variables of perceived usefulness, perceived ease of use, consumer trust, and anthropomorphism. The authors used an online survey for collecting the responses from 192 respondents and analyzed structural equation modelling. Results: Customer trust has shown the most decisive influence on customer attitude followed by Perceived Usefulness, Perceived Ease of Use. Also, the use of chatbots to make online shopping faster significantly affects the use of messenger chatbots for online shopping in the future. The authors explore various factors resulting in consumers’ favor of accepting chatbots as an interface for m-commerce. Conclusions: The findings indicate that organizations should design strategies to improve interaction with the customer by developing messenger chatbots for more trusting conversations. Further research could include a theoretical digital marketing approach to conversational commerce based on anthropomorphic digital technologies.
