Workflow Templates

SharePoint → Supabase → Google Drive Sync Workflow Overview This workflow is a multi-system document synchronization pipeline built in n8n, designed to automatically sync and back up files between Microsoft SharePoint, Supabase/Postgres, and Google Drive. It runs on a scheduled trigger, compares SharePoint file metadata against your Supabase table, downloads new or updated files, uploads them to Google Drive, and marks records as completed — keeping your databases and storage systems perfectly in sync. Workflow Structure Data Source:** SharePoint REST API for recursive folder and file discovery. Processing Layer:** n8n logic for filtering, comparison, and metadata normalization. Destination Systems:** Supabase/Postgres for metadata, Google Drive for file backup. SharePoint Sync Flow (Frontend Flow) Trigger:** Schedule Trigger Runs at fixed intervals (customizable) to start synchronization. Fetch Files:** Microsoft SharePoint HTTP Request Recursively retrieves folders and files using SharePoint’s REST API: /GetFolderByServerRelativeUrl(...)?$expand=Files,Folders,Folders/Files,Folders/Folders/Folders/Files Filter Files:** filter files A Code node that flattens nested folders and filters unwanted file types: Excludes system or temporary files (~$) Excludes extensions: .db, .msg, .xlsx, .xlsm, .pptx Normalize Metadata:** normalize last modified date Ensures consistent Last_modified_date format for accurate comparison. Fetch Existing Records:** Supabase (Get) Retrieves current entries from n8n_metadata to compare against SharePoint files. Compare Datasets:** Compare Datasets Detects new or modified files based on UniqueId, Last_modified_date, and Exists. Routes only changed entries forward for processing. File Processing Engine (Backend Flow) Loop:** Loop Over Items2 Iterates through each new or updated file detected. Build Metadata:** get metadata and Set metadata Constructs final metadata fields: file_id, file_title, file_url, file_type, foldername, last_modified_date Generates fileUrl using UniqueId and ServerRelativeUrl if missing. Upsert Metadata:** Insert Document Metadata Inserts or updates file records in Supabase/Postgres (n8n_metadata table). Operation: upsert with id as the primary matching key. Download File:** Microsoft SharePoint HTTP Request1 Fetches the binary file directly from SharePoint using its ServerRelativeUrl. Rename File:** rename files Renames each downloaded binary file to its original file_title before upload. Upload File:** Upload file Uploads the renamed file to Google Drive (My Drive → root folder). Mark Complete:** Postgres Updates the Supabase/Postgres record setting Loading Done = true. Optional Cleanup:** Supabase1 Deletes obsolete or invalid metadata entries when required.

Bulk WhatsApp Campaign Automation with Rapiwa API (Unofficial Integration) Who’s it for This n8n workflow lets you send bulk WhatsApp messages using your own number through Rapiwa API, avoiding the high cost and limitations of the official WhatsApp API. It integrates seamlessly with Google Sheets, where you can manage your contacts and messages with ease. Ideal for easy-to-maintain bulk messaging solution using their own personal or business WhatsApp number. This solution is perfect for small businesses, marketers, or teams looking for a cost-effective way to manage WhatsApp communication at scale. How it Works / What It Does Reads data from a Google Sheet where the Status column is marked as "pending". Cleans each phone number (removes special characters, spaces, etc.). Verifies if the number is a valid WhatsApp user using the Rapiwa API. If valid: Sends the message via Rapiwa. Updates Status = sent and Verification = verified. If invalid: Skips message sending. Updates Status = not sent and Verification = unverified. Waits for a few seconds (rate-limiting). Loops through the next item. The entire process is triggered automatically every 5 minutes. How to Set Up Duplicate the Sample Sheet: Use this format. Fill Contacts: Add columns like WhatsApp No, Name, Message, Image URL, and set Status = pending. Connect Google Sheets: Authenticate and link Google Sheets node inside n8n. Subscribe to Rapiwa: Go to Rapiwa.com and get your API key. Paste API Key: Use the HTTP Bearer token credential in n8n. Activate the Workflow: Let n8n take care of the automation. Requirements Google Sheets API credentials Configured Google Sheet (template linked above) WhatsApp (Personal or Business) n8n instance with credentials setup How to Customize the Workflow Add delay between messages**: Use the Wait node to introduce pauses (e.g., 5–10 seconds). Change message format**: Modify the HTTP Request node to send media or templates. Personalize content**: Include dynamic fields like Name, Image URL, etc. Error handling**: Add IF or SET nodes to capture failed attempts, retry, or log errors. Workflow Highlights Triggered every 5 minutes** using the Schedule Trigger node. Filters messages** with Status = pending. Cleans numbers* and *verifies WhatsApp existence** before sending. Sends WhatsApp messages** via Rapiwa (Unofficial API). Updates Google Sheets** to mark Status = sent or not sent and Verification = verified/unverified. Wait node** prevents rapid-fire sending that could lead to being flagged by WhatsApp. Setup in n8n 1. Connect Google Sheets Add a Google Sheets node Authenticate using your Google account Select the document and worksheet Use filter: Status = pending 2. Loop Through Rows Use SplitInBatches or a Code node to process rows in small chunks (e.g., 5 rows) Add a Wait node to delay 5 seconds between messages 3. Send Message via HTTP Node How the "Send Message Using Rapiwa" Node Sends Messages This node makes an HTTP POST request to the Rapiwa API endpoint: https://app.rapiwa.com/api/send-message It uses Bearer Token Authentication with your Rapiwa API key. When this node runs, it sends a WhatsApp message to the specified number with the given text and optional image. The Rapiwa API handles message delivery using your own WhatsApp number connected to their service. JSON Body**: { "number": "{{ $json['WhatsApp No'] }}", "message": "{{ $json['Message'] }}" } Sample Google Sheet Structure A Google Sheet formatted like this sample | SL | WhatsApp No | Name | Message | Image URL | Verification | Status | |----|----------------|------------------------|----------------------|---------------------------------------------------------------------------|--------------|---------| | 1 | 8801322827799 | SpaGreen Creative | This is Test Message | https://spagreen.sgp1.cdn.digitaloceanspaces.com/... | verified | sent | | 2 | 8801725402187 | Abdul Mannan Zinnat | This is Test Message | https://spagreen.sgp1.cdn.digitaloceanspaces.com/... | verified | sent | Tips Modify the Limit node to increase/decrease messages per cycle. Adjust the Wait node to control how fast messages are sent (e.g., 5–10s delay). Make sure WhatsApp numbers are properly formatted (e.g., 8801XXXXXXXXX, no +, no spaces). Store your Rapiwa API key securely using n8n credentials. Use publicly accessible image URLs if sending images. Always mark processed messages as "sent" to avoid duplicates. Use the Error workflow in n8n to catch failed sends for retry. Test with a small batch before going full-scale. Schedule the Trigger node for every 5 minutes to keep automation running.

What it does This workflow automates the creation and posting of a daily space image gallery to Slack. Every day at a scheduled time, it fetches three distinct images from NASA's public APIs: one from the Mars Rover, one from the EPIC satellite observing Earth, and one from the extensive Image Library. For each image, the workflow uses an AI model to generate a unique and poetic caption, transforming a simple image post into a more engaging piece of content. Finally, it combines these three images and their AI-generated captions into a single, beautifully formatted message and posts it to your designated Slack channel. As a bonus, it also saves a copy of the message to a Google Drive folder for archival purposes. How to set up Configure Variables: In the Workflow Configuration node, enter your NASA API Key in the nasaApiKey field and specify your target Slack channel name in the slackChannel field (e.g., general). Connect Credentials: You will need to add your credentials for the OpenAI Chat Model, Post to Slack, and Google Drive nodes. Activate Workflow: Once your credentials and variables are set, simply save and activate the workflow. Requirements A NASA API Key (free to generate). An OpenAI account and API key.

How to customize the workflow Adjust the Schedule: Change the trigger time or frequency in the Daily 10:00 - Start Poll node. Change AI Tone: Modify the system message in the AI Agent node to alter the style, tone, or language of the generated captions. Swap Image Sources: Update the URLs in the Fetch nodes to pull images from different NASA APIs or use different search queries. Add More Channels: Duplicate the Post to Slack node and modify it to send notifications to other services like Discord or Telegram.
