Developed and delivered a new Line Bot integration for Dify plugins, focusing on secure and reliable message flow between Line and Dify applications. The work, contributed to the langgenius/dify-plugins repository, established a reusable integration pattern by implementing webhook signature verification and forwarding messages to designated Dify apps. Configuration scaffolding was added, including endpoint definitions, manifest files, and environment examples, to streamline deployment and onboarding for future integrations. The project was built using Python and YAML, leveraging skills in API integration, backend development, and plugin development to ensure maintainability and extensibility for subsequent plugin integrations within the Dify ecosystem.
