Description
Overview
This article summary automation workflow streamlines the retrieval and delivery of updated articles using a no-code integration pipeline. Designed for content curators and knowledge workers, it efficiently fetches new articles from an external API and delivers structured summaries via messaging platforms. The workflow initiates with a manual or scheduled trigger and uses a binary file read node to determine the last synchronization timestamp.
Key Benefits
- Automates article retrieval and summary delivery with a scheduled or manual trigger.
- Filters and formats only relevant articles based on category and content structure.
- Maintains incremental updates by tracking last synced timestamps in local storage.
- Delivers concise article summaries directly to Telegram chats for immediate consumption.
- Supports scalable execution with batch processing and event-driven analysis of content.
Product Overview
This automation workflow starts with either a manual trigger or a cron-based schedule set to execute every 10 minutes. It reads a local binary JSON file containing the timestamp of the last successful synchronization. Using this timestamp, it queries an external API endpoint for articles updated since the last sync, specifying schema version 5 in the request. The HTTP request employs header-based authentication credentials managed within the environment, ensuring secure access without exposing sensitive keys.
The retrieved data payload undergoes filtering to isolate articles categorized explicitly as “article” and excludes those with child elements, focusing on leaf-node content. Each selected article is then transformed into a summary object containing title, author, summary, URL, and the saved date. These summaries are dispatched as formatted text messages to a configured Telegram chat, leveraging the Telegram API node with bot credentials. The workflow concludes by updating the last synced timestamp stored locally, ensuring subsequent runs only fetch new or modified content. Error handling follows platform defaults without custom retry strategies.
Features and Outcomes
Core Automation
This article summary automation workflow processes incoming trigger events, fetches incremental updates, and routes structured content for delivery. The filtering logic applies category checks and hierarchical assessments to isolate relevant articles from the API response, forming a precise orchestration pipeline.
- Single-pass evaluation of article updates using timestamp-based delta queries.
- Deterministic filtering by category and child element presence for content accuracy.
- Parallel processing of data for simultaneous update time setting and article batching.
Integrations and Intake
The workflow integrates with a RESTful API through an authenticated HTTP request using header credentials. It accepts scheduling events or manual triggers and requires a local JSON file input indicating the last synchronization timestamp.
- Readwise API for incremental article retrieval with schema version 5.
- Telegram API for message delivery using bot authentication and chat ID configuration.
- Local file system access to read and write synchronization state in JSON format.
Outputs and Consumption
Outputs consist of text messages formatted with article metadata, delivered asynchronously to Telegram chats. The workflow also updates synchronization metadata in a local JSON file to maintain incremental state across executions.
- Telegram messages containing article title, author, summary, and URL.
- Updated local JSON file with the current synchronization timestamp.
- Asynchronous message dispatch ensuring non-blocking workflow execution.
Workflow — End-to-End Execution
Step 1: Trigger
The workflow initiates either via a manual trigger node activated by user interaction or a cron trigger set to execute every 10 minutes. Both triggers funnel into the same processing sequence, enabling flexible scheduling or on-demand execution.
Step 2: Processing
Reads a local binary JSON file that stores the last synchronization timestamp. The binary content is converted to JSON to extract the timestamp, which is then used to filter the API request for updated articles. Basic presence checks ensure the file exists and contains valid data, while failures default to platform behavior.
Step 3: Analysis
The HTTP request fetches documents updated since the last sync using query parameters to specify the schema version and update filter. The response is filtered for documents categorized as articles without child nodes. Each filtered article is mapped to a simplified JSON object including key metadata fields.
Step 4: Delivery
Each article summary is formatted into a textual message and sent to a configured Telegram chat via the Telegram API node. After dispatch, the workflow updates the local JSON file with the current timestamp to mark synchronization completion, ensuring accurate incremental data retrieval on subsequent runs.
Use Cases
Scenario 1
Content managers need to stay updated with newly published articles without manual checks. This automation workflow periodically queries the Readwise API for updates and delivers concise summaries to Telegram chats. The result is timely access to relevant articles with minimal manual intervention.
Scenario 2
Teams require an efficient way to curate and disseminate article highlights internally. The workflow filters articles by category and structure, formats summaries, and sends them directly to group chats. This ensures consistent content delivery and reduces the risk of missing critical updates.
Scenario 3
Developers want to integrate incremental content synchronization into their knowledge bases without building custom scripts. This orchestration pipeline leverages timestamp-based queries and local state management to automate updates, returning structured article data in each execution cycle.
How to use
After importing this workflow into n8n, configure the “Config” node with your Telegram chat ID and local file path for storing the last synchronization timestamp. Provide valid header authentication credentials for the API request node. Activate either the manual trigger or enable the 10-minute cron schedule to run the workflow automatically. Upon execution, expect article summaries formatted and sent to Telegram, with synchronization state updated accordingly.
Comparison — Manual Process vs. Automation Workflow
| Attribute | Manual/Alternative | This Workflow |
|---|---|---|
| Steps required | Multiple manual API queries, filtering, formatting, and message sending | Single automated sequence handling all retrieval, processing, and delivery |
| Consistency | Variable; prone to human error and missed updates | Deterministic filtering and timestamp tracking ensure uniform results |
| Scalability | Limited by manual effort and error handling capabilities | Handles incremental loads automatically with scheduled triggering |
| Maintenance | Requires ongoing manual oversight and script updates | Low maintenance; uses platform defaults for error handling and retries |
Technical Specifications
