1.1 Workflow description

Title: Send WooCommerce discount coupons to customers via WhatsApp using Rapiwa API
Workflow name: Send WooCommerce discount coupons to customers via WhatsApp using Rapiwa API

Who is this for?

This workflow is ideal for WooCommerce store owners who want to automatically send promotional WhatsApp messages to their customers when new coupons are created. It’s designed for marketers and eCommerce managers looking to boost engagement, streamline coupon sharing, and track campaign performance effortlessly through Google Sheets.

Overview

This workflow listens for WooCommerce coupon creation events (coupon.created) and uses customer billing data to send promotional WhatsApp messages via the Rapiwa API. The flow formats the coupon data, cleans phone numbers, verifies WhatsApp registration with Rapiwa, sends the promotional message when verified, and logs each attempt to Google Sheets (separate sheets for verified/sent and unverified/not sent).

What this Workflow Does

Listens for new coupon creation events in WooCommerce via the WooCommerce Trigger node
Retrieves all customer data from the WooCommerce store
Processes customers in batches to control throughput
Cleans and formats customer phone numbers for WhatsApp
Verifies if phone numbers are valid WhatsApp accounts using Rapiwa API
Sends personalized WhatsApp messages with coupon details to verified numbers
Logs all activities to Google Sheets for tracking and analysis
Handles both verified and unverified numbers appropriately

Key Features

Automated coupon distribution: Triggers when new coupons are created in WooCommerce
Customer data retrieval: Fetches all customer information from WooCommerce
Phone number validation: Verifies WhatsApp numbers before sending messages
Personalized messaging: Includes customer name and coupon details in messages
Dual logging system: Tracks both successful and failed message attempts
Rate limiting: Uses batching and wait nodes to prevent API overload
Data formatting: Structures coupon information for consistent messaging

Google Sheet Column Structure

A Google Sheet formatted like this ➤ sample The workflow uses a Google Sheet with the following columns to track coupon distribution:

name	number	email	address1	couponCode	couponTitle	couponType	couponAmount	createDate	expireDate	validity	status
Abdul Mannan	8801322827799	[email protected]	mirpur-DOHS	62dhryst	eid offer 2025	percent	20.00	2025-09-11 06:08:02	2025-09-15 00:00:00	unverified	not sent
Abdul Mannan	8801322827799	[email protected]	mirpur-DOHS	62dhryst	eid offer 2025	percent	20.00	2025-09-11 06:08:02	2025-09-15 00:00:00	verified	sent

Requirements

n8n instance with the following nodes: WooCommerce Trigger, Code, SplitInBatches, HTTP Request, IF, Google Sheets, Wait
WooCommerce store with API access
Rapiwa account with API access for WhatsApp verification and messaging
Google account with Sheets access
Customer phone numbers in WooCommerce (stored in billing.phone field)

Important Notes

Phone Number Format: The workflow cleans phone numbers by removing all non-digit characters. Ensure your WooCommerce phone numbers are in a compatible format.
API Rate Limits: Rapiwa and WooCommerce APIs have rate limits. Adjust batch sizes and wait times accordingly.
Data Privacy: Ensure compliance with data protection regulations when sending marketing messages.
Error Handling: The workflow logs unverified numbers but doesn't have extensive error handling. Consider adding error notifications for failed API calls.
Message Content: The current message template references the first coupon only (coupons[0]). Adjust if you need to handle multiple coupons.

Promote YouTube uploads to social channels with DeepSeek and Posta

## Quick overview This workflow fetches the latest video from a YouTube channel feed, generates platform-specific promo captions with DeepSeek, and creates draft promotion posts in Posta for active social media accounts. You can automatically promote your videos to all your social media. Add a "publish" at the end for auto-post. ## How it works 1. Runs manually when you click “Execute workflow”. 2. Fetches your YouTube channel RSS feed over HTTP, parses the XML, and extracts the latest video’s title, description, thumbnail URL, and link. 3. Downloads the video thumbnail and uploads it to Posta to create a reusable media asset. 4. Retrieves your social accounts from Posta, keeps only active accounts, and de-duplicates them to one account per platform. 5. Combines the latest video data with each target platform and asks DeepSeek (via an n8n LangChain LLM chain) to write a tailored promotional caption per platform. 6. Tags each generated caption with its platform and merges it back to the matching Posta social account. 7. Creates a draft Posta post per selected account, attaching the uploaded thumbnail and the platform-specific caption and video link. 8. (Optional) Add a "publish a post" at the end to automatically post to the social media channels (If you are feeling brave and trust the LLM), ## Setup 1. Add a Posta API credential and select it in the Posta nodes that list accounts, upload media, and create posts. 2. Add a DeepSeek API credential and select it in the DeepSeek Chat Model node. 3. Update the YouTube channel feed URL (channel_id) in the HTTP request that downloads the YouTube feed. 4. Review your Posta social accounts to ensure the intended accounts are marked active and have the correct platform values for de-duplication. ## Additional info Video explanation: https://youtu.be/tTWaYb71YyA

Post scheduled Threads updates from Google Sheets with error tracking

## Quick overview This workflow runs hourly to read the next pending post from Google Sheets, publishes it to Threads via the Threads Graph API, and then updates the sheet with published or failed status plus timestamps and error details. ## How it works 1. Runs every hour on a schedule. 2. Reads the first row in Google Sheets where the status column equals pending. 3. Retrieves the authenticated Threads account’s user ID from the Threads Graph API. 4. Creates a Threads text post container using the content from the pending Google Sheets row. 5. Publishes the post to Threads and updates the same Google Sheets row as published with posted_at and updated_at timestamps. 6. If any Threads API call fails, records the error message and marks the corresponding Google Sheets row as failed with an updated_at timestamp. ## Setup 1. Create a Meta app and generate a Threads access token, then add it to an HTTP Header Auth credential used for the Threads Graph API requests. 2. Set up a Google Sheets Service Account credential in n8n and share your target spreadsheet with the service account email. 3. Replace the placeholder Google Sheet ID in all Google Sheets nodes and confirm the sheet name is Sheet1 (or update it to match your sheet). 4. Ensure your sheet has the required columns (row_number, content, status, posted_at, updated_at, error_message) and set status to pending for posts you want published.

Send a daily product newsletter with Google Sheets and Gmail

## Quick Overview This workflow runs daily at 08:00, pulls products scheduled for today from Google Sheets, generates an HTML newsletter email, and sends it to each subscriber via Gmail. ## How it works 1. Runs every day at 08:00 on a schedule. 2. Reads all rows from the `newsletter_products` sheet in Google Sheets. 3. Keeps only products whose `send_date` matches today’s date and stops if none are found. 4. Builds an HTML email and subject line containing a card for each product (image, description, and optional referral link). 5. Reads the subscriber list from the `newsletter_recipients` sheet in Google Sheets. 6. Sends the generated newsletter to each recipient individually using Gmail. ## Setup 1. Create or copy a Google Sheets document with `newsletter_products` (including a `send_date` column) and `newsletter_recipients` (including an `email` column). 2. Add a Google Sheets OAuth2 credential in n8n and paste your Google Sheet ID into the Config step. 3. Add a Gmail OAuth2 credential and confirm the sender mailbox to use for sending the newsletter. 4. Add products and recipients to the sheet, run a test execution, and adjust the schedule/timezone if needed before activating.
