1.1 Workflow description

Title: Auto-cleanup of 对象存储 files older than 2 weeks (+ Telegram notifications)
Workflow name: Auto-cleanup of 对象存储 files older than 2 weeks (+ Telegram notifications)

This workflow automatically connects to a 对象存储 bucket (via S3-compatible API), filters out files older than 14 days, deletes them, and then sends a Telegram notification for each deletion. It runs on a daily schedule.

🕘 Schedule Trigger Executes the workflow once a day at a specified hour (e.g., 9 AM).

📦 S3 Node – List Files Retrieves all objects from a specific folder (prefix) in a 对象存储 bucket using the S3 API.

🔎 Code Node – Filter Files Older Than 2 Weeks Filters the retrieved files by comparing their LastModified timestamps to the current date. Files older than 14 days (2 weeks) are selected for deletion.

🗑️ S3 Node – Delete File Deletes each filtered file from the R2 bucket.

📨 Telegram Node – Notify Deletion Sends a Telegram message with the name of the deleted file to a specified chat ID. The message includes:

Export WordPress data to a CSV file

## Quick Overview This workflow manually exports all records from a WordPress site, converts the returned JSON into a CSV file, and saves the CSV to disk on the n8n server. ## How it works 1. Starts when you manually click Execute in n8n. 2. Fetches all available items from your connected WordPress site via the WordPress API. 3. Converts the WordPress JSON response into a CSV file. 4. Writes the generated CSV to the n8n server as `data.csv`. ## Setup 1. Add WordPress API credentials in n8n (site URL, username, and an Application Password). 2. Choose the WordPress resource to export in the WordPress node and confirm the data shape matches what you want in the CSV. 3. Update the output file path/name in the file-writing step and ensure the target directory is writable on your n8n host (for example `/home/node/.n8n/data.csv`).

Aggregate shipment tracking statuses with FedEx, UPS and DHL

## Quick Overview This workflow runs every 15 minutes to fetch active shipments from an n8n Data Table, query FedEx, UPS, or DHL tracking APIs with circuit-breaker protection, normalize each response into a shared status schema, and upsert the latest status back into the same table. ## How it works 1. Runs every 15 minutes on a schedule. 2. Loads all rows from the n8n Data Table `shipment_tracking` and filters out shipments already marked as DELIVERED or RETURNED_TO_SENDER. 3. Routes each remaining shipment by `carrier` and marks unsupported carriers with a canonicalStatus of UNKNOWN. 4. For FedEx, UPS, and DHL shipments, checks a per-carrier circuit breaker and either calls the carrier’s tracking API or skips the call when the breaker is open. 5. Normalizes each carrier response (or skip) into a canonical status (for example PRE_TRANSIT, IN_TRANSIT, OUT_FOR_DELIVERY, DELIVERED, EXCEPTION, UNKNOWN) while updating the breaker state based on 429/5xx/network failures. 6. Merges all carrier results and upserts the latest fields back into the `shipment_tracking` Data Table using `trackingNumber` as the match key. ## Setup 1. Create the n8n Data Table named `shipment_tracking` with columns such as `trackingNumber`, `carrier`, `canonicalStatus`, `rawStatus`, `breakerState`, `httpStatus`, and `checkedAt`, and seed it with shipments (use lowercase carriers: `fedex`, `ups`, `dhl`). 2. Add OAuth2 credentials for the FedEx Track API and select them in the FedEx HTTP request step. 3. Add OAuth2 credentials for the UPS Track API and select them in the UPS HTTP request step. 4. Add DHL API authentication (as configured for the DHL request in this template) and select it in the DHL HTTP request step. 5. Activate the workflow so workflow static data persists between runs and the circuit breaker state is maintained.

Clean up watched Jellyfin media and completed torrents with Transmission

## Quick Overview This scheduled workflow cleans up watched media in Jellyfin and removes completed torrents from Transmission by calling both APIs, deleting played items in Jellyfin, refreshing the Jellyfin library, and deleting torrents (including local data) once they reach the completed status. ## How it works 1. Runs daily on a schedule at the configured hour. 2. Sets the Jellyfin base URL, Jellyfin user ID, and Transmission base URL used for subsequent API calls. 3. Fetches played Movies and Episodes from Jellyfin for the configured user, deletes each returned item, and triggers a Jellyfin library refresh. 4. Calls the Transmission RPC endpoint to retrieve the required X-Transmission-Session-Id, then re-requests the torrent list using that session header. 5. Splits the Transmission response into individual torrents, filters to those with status 6 (completed), and removes each matching torrent while also deleting its local data. ## Setup 1. Add Jellyfin HTTP Header Auth credentials (for example, an API key header) and fill in the Jellyfin server URL and target Jellyfin user ID in the Variables step. 2. Add Transmission Bearer Auth credentials and set your Transmission base URL in the Variables step. 3. Confirm your Transmission instance allows RPC access at `/transmission/rpc` and that your Jellyfin server exposes the `/Users/{userId}/Items`, `/Items/{id}`, and `/Library/Refresh` endpoints for the provided credentials.
