n8n Workflow Auto Backup to GitHub

This workflow implements an automatic message cleanup feature for Discord channels. It scans all channels of a specified server at scheduled intervals each day, automatically deleting messages that are older than seven days to keep the channels tidy. By appropriately setting wait times, it effectively avoids API call rate limits, ensuring the smooth execution of tasks and reducing the risk of being banned. This significantly alleviates the burden of manual management for community operators and business users, enhancing channel activity and information security.

This workflow is triggered by a Telegram message, listening for specific commands input by the user. It automatically extracts the version number and calls the GitHub API to query the release information for the corresponding version, greatly simplifying the traditional version inquiry process. Users only need to send a simple command to instantly obtain detailed information about the target version, enhancing work efficiency and response speed. It is suitable for development teams, operations personnel, and product managers who need to quickly access project version information.

This workflow assigns values to variables through the "Set" node, supporting various data types such as numbers, strings, and boolean values, with a simple and intuitive operation. It addresses the need for dynamically managing variables in automated processes, allowing subsequent nodes to flexibly call preset values, thereby enhancing the flexibility and maintainability of the workflow. It is suitable for scenarios such as data processing and conditional judgment, helping users quickly establish variable assignment logic and gain a deeper understanding of variable management and data transmission mechanisms.

This workflow receives POST Webhook requests in real-time from the Retell voice agent, allowing for flexible orchestration of business processes and supporting features such as automatic confirmations for the hotel and catering industries. The booking information entered by users can be extracted and used to generate dynamic responses, enabling seamless integration with external systems and enhancing the automation service level of the voice bot. The workflow also provides detailed annotations and operational guidance, facilitating quick onboarding and personalized expansion to meet various voice interaction scenario needs.

This workflow receives Twilio SMS messages and utilizes Redis for message buffering, combining it with an AI intelligent agent to merge replies to multiple messages from users. It is capable of delaying responses when users send messages rapidly in succession, allowing it to determine whether the input has ended, thereby providing a cohesive, one-time AI response. This mechanism effectively avoids fragmented replies, enhancing the fluidity of conversations and the user experience. It is suitable for scenarios such as enterprise customer service, marketing interactions, and intelligent SMS assistants.

This workflow implements a Redis distributed locking mechanism to ensure that only one instance is executed at any given time, effectively preventing data conflicts caused by duplicate and concurrent operations. It supports automatic identification of duplicate requests and skips execution, ensuring the uniqueness and order of tasks. This is suitable for automated scenarios in multi-user or multi-system environments, such as order processing and data synchronization. Additionally, the workflow promptly releases the lock upon completion, ensuring effective resource management.

This workflow automatically sends SMS notifications to preset numbers by monitoring the user's departure from home, ensuring that family members, colleagues, or other devices can be promptly informed of the user's outing. Utilizing Pushcut triggers and Twilio SMS services, it achieves efficient and personalized instant reminders, enhancing safety and communication efficiency in both personal and work life. It is suitable for individual users and managers who wish to automate reminders.

This workflow automatically captures errors from other workflows and sends detailed error notifications via Telegram in real-time. The notification includes the workflow name, timestamp, execution link, last executed node, and detailed error information, helping users quickly locate the issue. It supports multiple retry attempts for sending notifications, ensuring reliable delivery of information, thereby enhancing the stability of the automation system and operational efficiency. It is suitable for enterprise-level automation monitoring, DevOps teams, and business systems that require immediate error alerts.
