1.1 Workflow description

Title: Auto-post Facebook and Instagram content with OpenAI, Google Sheets and review
Workflow name: Auto-post Facebook and Instagram content with OpenAI, Google Sheets and review

Who is this for? This workflow is designed for social media managers, marketing agencies, and business owners who want to automate their Facebook and Instagram posting without losing quality control. It is perfect if you manage content in Google Sheets and want AI to write your captions, but you still need a human to review the final post before it goes live to your audience.

What this workflow does This workflow acts as a complete social media auto-poster. It reads your product inventory from Google Sheets, finds items that haven't been promoted recently, and uses OpenAI to write a professional, engaging caption. Before publishing, the workflow pauses and sends you a simple web form. Once you click "Approve," it automatically publishes the post to Facebook and Instagram, then logs the successful post back in your Google Sheet.

Key Features

Smart Google Sheets Tracking: Uses your spreadsheet as an inventory tracker to ensure you never over-promote the same product twice.
AI Copywriting: Automatically drafts platform-optimized, emoji-free captions based on your product data.
Approval Gate: Pauses the automation to let you manually review and approve the AI-generated content via an n8n web form.
Multi-Platform Auto-Posting: Connects directly to the Facebook Graph API to publish to your Facebook Page and Instagram Business Account.

How it works

Trigger: Open the n8n form and choose to promote a specific product or a general agency pitch.
Selection: The workflow scans your Google Sheet and picks the item with the lowest "Times Posted" count.
Generation: OpenAI writes a tailored caption for the selected item.
Review: You receive an interactive prompt to review the text and image URL.
Publishing: Upon approval, it posts instantly to Meta (Facebook/Instagram) and increments the post count in your Google Sheet.

Set up steps Estimated time: 10 minutes

Google Sheets: Connect your Google credential to the Sheets nodes and add your Spreadsheet ID.
OpenAI Key: Add your API key to the "AI Copywriter" node.
Meta API: Connect your Facebook Graph API credentials to the FB/IG nodes and ensure your Page ID is correct.
Run: Click "Test URL" on the Pixril Dispatcher form to trigger your first post!

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.
