Assign Values to Variables Using the Set Node
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.

Assign Values to Variables Using the Set Node
Key Features and Highlights
This workflow utilizes n8n’s “Set” node to assign values to variables, supporting multiple data types including numbers, strings, and booleans. The operation is straightforward and intuitive, enabling users to quickly define and modify variable content.
Core Problem Addressed
It addresses the need for dynamically setting and managing variables within automation workflows, allowing subsequent nodes to flexibly reference these predefined values. This enhances the workflow’s flexibility and maintainability.
Application Scenarios
Ideal for scenarios requiring initialization or updating of variable values within automation processes, such as data processing, conditional logic, and configuration parameter passing. It lays a foundation for more complex automation tasks.
Main Workflow Steps
- Manually trigger the workflow start using the “Manual Trigger” node by clicking “execute”;
- Use the “Set” node to assign values to variables, including a numeric variable (20), a string variable (“From n8n with love”), and a boolean variable (true);
- After assignment, the variables are available for use by subsequent workflow nodes.
Systems or Services Involved
This workflow exclusively uses n8n’s built-in nodes “Manual Trigger” and “Set” without any external system integrations, facilitating rapid deployment and testing.
Target Users and Value
Suitable for n8n beginners or automation engineers who need to quickly build variable assignment logic. By simply setting variables, it helps users better understand and master variable management and data passing mechanisms within n8n workflows.
Custom Function Webhook Workflow Connecting Retell Voice Agent
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.
Twilio SMS AI Intelligent Response Buffering Workflow
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.
Redis Distributed Lock Control Workflow
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.
Send an SMS to a Number Whenever You Go Out
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.
Error Handler send Telegram
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.
Bitbucket Repository Push Trigger
This workflow automatically triggers code changes by listening in real-time to push events from the Bitbucket repository, ensuring that subsequent automation processes start promptly. It addresses the inefficiencies of traditional code updates that rely on manual checks or scheduled polling, enhancing response speed. This solution is suitable for continuous integration, deployment, and code review scenarios, providing an efficient automation solution for development teams and DevOps engineers.
Auto Starter Workflow
This workflow is primarily used to automatically initiate workflows that have the specific label "Auto start," addressing the issue of workflows not running automatically after import. It can be integrated into the automated deployment pipeline to ensure that relevant workflows are automatically activated after container restarts or updates, reducing manual intervention and improving operational efficiency. It is suitable for operations engineers and automation developers, simplifying workflow maintenance and management.
