Retry Execution Hourly
This workflow is designed to automatically detect and periodically retry failed execution tasks, ensuring the stability and reliability of automated processes. Through scheduled triggers and automatic logins, the system can filter out failed records that have not been successfully retried and initiate retry requests one by one, significantly improving the continuity and efficiency of business processes while reducing manual intervention. It is suitable for various automated scenarios that require high availability.

Retry Execution Hourly
Key Features and Highlights
This workflow implements automatic detection and periodic retry of failed executions (Error executions) within the n8n platform, ensuring tasks automatically resume upon encountering exceptions. It significantly enhances the stability and reliability of automation processes. By leveraging scheduled triggers, automatic login to the n8n instance, filtering of unsuccessfully retried failed executions, and initiating retry requests one by one, it perfects the error handling mechanism.
Core Problems Addressed
In real-world automation scenarios, some execution tasks may fail due to transient faults. Manual monitoring and retrying are time-consuming and prone to errors. This workflow automates the monitoring of failed tasks and completes retry operations automatically, preventing omissions and delays, thereby improving the continuity and efficiency of business processes.
Application Scenarios
- Enterprises or teams managing numerous workflows on the n8n automation platform that require high availability of critical processes.
- Periodic detection and automatic recovery of failed automation tasks to reduce manual intervention.
- Suitable for automatic error handling across various business scenarios such as data synchronization, notification delivery, and system integration.
Main Process Steps
- Scheduled Trigger: Initiate the workflow hourly using the Schedule Trigger node.
- Configure Login Information: Set the n8n instance URL and login credentials in the Set node.
- Automatic Login to n8n Instance: Use the HTTP Request node to call n8n’s REST API for login and obtain session information.
- Retrieve Failed Executions List: Use n8n nodes to call the API and filter all executions with the status “error.”
- Filter Out Already Retried Records: Apply conditional logic to exclude executions that have been successfully retried.
- Batch Process Failed Executions: Handle failed execution tasks in batches and loops.
- Automatic Retry Execution: Invoke the n8n retry API via HTTP requests to trigger automatic retries of failed executions.
- No-Operation Branch: Leave executions that do not require retry unchanged.
Involved Systems or Services
- n8n automation platform and its REST API
- HTTP Request node for API interactions
- Scheduled Trigger for periodic execution
- Conditional logic and batch processing control nodes
Target Users and Value
- Automation engineers and developers responsible for ensuring stable operation of n8n workflows.
- Enterprise digital transformation teams aiming to enhance the robustness of automated tasks.
- Any users managing complex workflows on the n8n platform who seek to minimize manual intervention and automate failure handling.
- This workflow helps users save monitoring and maintenance costs while improving the self-healing capability and business continuity of automation systems.
Send Daily Weather Updates via Push Notification Using Spontit
This workflow automatically retrieves weather information for a specified city (such as Berlin) every day and sends temperature reminders to users through a push service. By using scheduled triggers, users can receive the latest weather updates in the morning, eliminating the hassle of manual checks. This process not only enhances the efficiency of information delivery but also helps users plan their daily activities more effectively. It is suitable for individual users, businesses, and service providers, thereby improving the overall user experience.
Manual Trigger to Invoke AWS Lambda Function Workflow
This workflow allows users to quickly trigger and invoke serverless functions pre-deployed on AWS Lambda by manually clicking the "Execute" button, simplifying the execution process of cloud computing tasks. Users can achieve flexible function calls without needing to log into the AWS Management Console or write code, making it suitable for scenarios such as development debugging, event triggering, and automation tasks, which is particularly convenient for cloud service developers and operations personnel.
n8n Workflow Credentials Intelligent Query Assistant
This workflow automates the retrieval and storage of all workflows and their node credentials within the automation platform. It incorporates AI-powered querying, allowing users to quickly check the usage of specific application credentials through natural language. The credential information is stored in a local SQLite database, ensuring data security, enhancing management efficiency, and addressing the issues of credential dispersion and inconvenient querying. It is suitable for various scenarios, including platform administrators, developers, and team collaboration.
DigitalOcean Cloud Server Automated Creation
This workflow automates the creation of cloud server instances by calling the DigitalOcean API, allowing users to customize the server name, region, specifications, and operating system image. It simplifies the cumbersome manual creation steps, avoids repetitive tasks, enhances deployment efficiency, and ensures configuration accuracy. It is suitable for various scenarios, including startup teams, operations and maintenance personnel, and educational training, helping to quickly set up and manage cloud resources while lowering the operational threshold.
Git Automation Workflow
This workflow, once manually triggered, automatically completes the addition, commit, and push operations of specific files in a Git repository, simplifying the execution process of Git commands. It effectively addresses the issues of cumbersome and error-prone manual operations, allowing code changes to be submitted to the remote repository quickly and in a standardized manner. This is particularly suitable for development teams and individual projects that require frequent updates to documents or code, enhancing code management efficiency.
PagerDuty and Jira Cross-Platform Incident Management Automation Workflow
This workflow implements the automatic synchronization of PagerDuty alert events with Jira tasks, combined with the Mattermost instant messaging platform, covering the entire process management from alert triggering to handling and closure. By automatically creating tasks, updating statuses, and providing multi-channel notifications, it significantly enhances cross-system collaboration efficiency, addressing issues of information inconsistency and response delays, allowing team members to track event statuses in real time and improve work efficiency. It is particularly suitable for IT operations and DevOps teams, helping to respond quickly to urgent failures.
Standup Bot - Worker
This workflow automates the management of daily stand-up meetings for the team by integrating with the Mattermost platform. It regularly reminds members to fill out reports, collects and generates summaries, and publishes them to a designated channel. Users can customize stand-up meeting settings through Slash commands, allowing for flexible adjustments to the time, frequency, and questions, thereby enhancing communication efficiency. By creating private chat channels, it ensures that each member receives reminders in a timely manner, addressing the cumbersome information collection issues often found in traditional stand-up meetings. This workflow is suitable for various teams that require regular communication and status synchronization.
Backup n8n Workflows to Bitbucket
This workflow is designed to automatically back up all workflows to a Bitbucket code repository, ensuring data security and version management. It executes on a scheduled daily basis, automatically detecting any additions or changes to the workflows and only synchronizing the parts that need to be updated, thereby saving resources. Additionally, it dynamically calculates request intervals to avoid API call frequency limits, ensuring an efficient and stable backup process. It is suitable for teams and individuals who need to regularly back up and manage automated processes.
