LINE remains one of the most popular messaging platforms across Asia. Integrating it with MaviBot gives you access to millions of users and enables automated customer communication through one of the region's leading messengers.

This guide walks you through the entire setup process—from creating your LINE account to connecting it with MaviBot and sending your first messages.

Variable Description
