Retry on Fail Except for Known Error Template
This workflow implements an intelligent automatic retry mechanism that effectively manages exceptions in automated tasks. It differentiates between "known errors" and other errors; for unknown errors, it will automatically retry until the maximum number of attempts is reached, while known errors are directly marked and skipped for retry. This design enhances the stability of the process and the efficiency of resource utilization, making it particularly suitable for scenarios such as API calls and data synchronization, ensuring a quick recovery in the event of temporary failures.

Retry on Fail Except for Known Error Template
Key Features and Highlights
This workflow implements an automatic retry mechanism that intelligently distinguishes between "known errors" and other errors. For unknown errors, the workflow automatically waits for a specified interval before retrying, up to a maximum retry count. For specific known errors (e.g., "could not be found"), it skips retries, marks the error as known, and proceeds without retrying. This approach improves efficiency and avoids unnecessary retry attempts.
Core Problems Addressed
In automated processes, operations such as network requests or data retrieval often fail due to transient issues, causing process interruptions or exceptions. This workflow ensures automatic recovery from temporary failures by configuring retry counts and wait times. Meanwhile, it reduces resource waste and false alarms by identifying specific error types and avoiding futile retries.
Application Scenarios
- Automated workflows involving API calls or data fetching that may encounter intermittent failures
- System integrations requiring differentiation between business-related "known errors" and transient errors
- Processes needing automatic retries on failures to ensure stability and high availability
- Suitable for data synchronization, automated monitoring, task execution, and similar scenarios
Main Process Steps
- Manual Trigger to start the workflow
- Initialize retry counter (Set tries)
- Execute the core node (Replace Me — to be replaced with the actual data retrieval or operation node, with error output enabled)
- On success, proceed to the “Success” node for subsequent logic
- On failure, determine if the error is a known error (Catch known error)
- If a known error, proceed to the “Known Error” node and stop retrying
- If not a known error, wait for a fixed interval (Wait node, default 5 seconds) and increment retry count
- Check if retry count exceeds the maximum (default 3 retries)
- If not exceeded, retry from the beginning
- If exceeded, stop execution and raise an error (Retry limit reached)
Involved Systems or Services
This template serves as a generic retry mechanism example and does not directly integrate with specific external services. Please replace the “Replace Me” node with concrete invocation nodes (e.g., HTTP requests, database queries, third-party APIs) according to your actual use case to fit different business requirements.
Target Users and Value
- Automation developers and operations engineers who need stable management of API calls and data extraction tasks
- Enterprises and teams aiming to enhance failure resilience of automated tasks
- Technical personnel seeking to optimize retry strategies by differentiating error types
- Users looking for a simple, customizable retry template to reduce system failure rates
This workflow leverages flexible error recognition and retry design to help users efficiently manage exceptions in automated tasks, improving overall process stability and fault tolerance. By simply replacing the core operation node, it can be rapidly adapted to various business scenarios.
Netlify Deployment Failure Notification Automation Workflow
This workflow monitors the Netlify deployment status in real-time. In the event of a deployment failure, it immediately sends a detailed notification via Slack, including the site name, error message, and deployment link. This automation significantly enhances the team's response speed to deployment issues, ensuring that critical failure information is not overlooked. It is suitable for website development and operations teams, helping to quickly identify and resolve problems, thereby ensuring the smooth progress of project launches.
Weekly Failures Report
This workflow automatically queries the execution records of a specified workflow every week, filtering out the failed executions from the past week, and sends a summary report to the user via Telegram. This feature helps users stay informed about any anomalies in workflow operations, improves operational efficiency, and reduces the risk of business interruptions. It is suitable for automated operations teams and enterprise users who need to track process status. Through this automated mechanism, users can effectively monitor the health status of workflows without manual intervention.
Slack-GitHub User Info
This workflow automatically queries detailed information for a specified GitHub username by receiving user commands in Slack, and sends the organized information back to Slack as a message, making it easy for team members to quickly access developer information. It effectively addresses the cumbersome process of manually searching for information, enhancing communication efficiency and collaboration experience. By integrating Webhook triggers, flexible GraphQL queries, and custom functions, it ensures that the information is accurate and free of redundancy, making it suitable for various scenarios such as development teams, project managers, and human resources.
Error Notification Workflow
This workflow focuses on the automatic capture and processing of error events from other workflows, generating real-time error alert messages and sending them to designated groups via Telegram. This mechanism effectively shortens fault response time, enhances system stability, and ensures that operations and business personnel can promptly understand issues. It is suitable for automated process monitoring, unified error management, and status tracking for DevOps teams. With simple configuration, users can achieve efficient error notifications, ensuring business continuity.
FetchGithubIssues
This workflow regularly fetches the latest open issues with the "Bug" label from a specified GitHub repository, focusing on critical issues with fewer than 5 comments. It automatically retrieves and filters qualifying issues every 10 minutes, pushing their titles and links in real-time to a designated Telegram user for quick bug monitoring and notifications. This approach helps the development team stay informed about important defects in the project, enhances issue response speed and communication efficiency, and simplifies the manual monitoring process.
n8n_check
This workflow regularly monitors the RSS Feed of n8n's official GitHub Releases, automatically filtering for new version information containing specific keywords that were released on the same day. It sends push notifications through a Telegram group and AWS SES email to ensure that users are promptly informed of important updates. It supports scheduled daily runs as well as manual triggers, helping operations and development personnel efficiently track the status of the tool, enhancing the timeliness and convenience of information retrieval, and avoiding the need for frequent manual checks.
User Information Management Chained Request Workflow
This workflow is triggered with a single click, allowing for the retrieval, creation, and updating of user information. It demonstrates an efficient process using HTTP request nodes for REST API chaining. The workflow supports retrieving user lists, adding new users, and updating user information, automatically linking the operational steps to ensure a smooth data flow. It significantly enhances the efficiency and accuracy of user data management, making it particularly suitable for scenarios that require frequent maintenance of user information, reducing human errors and ensuring real-time data updates.
Automatic Association of GitHub Pull Requests with Pipedrive Contacts
This workflow automatically listens for Pull Request events in GitHub and retrieves the corresponding contacts in the Pipedrive CRM system based on the email of the PR submitter. If a contact is found, the system adds PR-related notes to their record, ensuring that development activities are synchronized in real-time with customer information. This automation significantly enhances the collaboration efficiency between the software development team and the sales team, reduces errors caused by manual operations, and helps the company better manage customer relationships and project progress.
