Quick Overview

This workflow runs daily and reads a Google Sheets content calendar to auto-publish scheduled posts to Instagram and Facebook via the Meta Graph API, then posts the same content to LinkedIn and updates the sheet with posting results.

How it works

  1. Runs every day at 19:00 in the Africa/Casablanca timezone.
  2. Reads rows from a Google Sheets “Content_Calendar” sheet and keeps only items scheduled for today with a status of “pending”.
  3. Prepares the post payload by building the final caption (caption plus hashtags) and determining whether the content is an image or an Instagram Reel, optionally generating a Cloudinary-transformed image URL.
  4. If the item is an image, it creates and publishes an Instagram media container through the Meta Graph API, then posts the same image to a Facebook Page.
  5. If the item is a Reel, it creates an Instagram Reel container through the Meta Graph API, waits for processing, publishes it, and then uploads the video to a Facebook Page.
  6. Downloads the posted image and publishes the captioned post to LinkedIn.
  7. Updates the Google Sheets row as “posted” with timestamps/IDs on success, or marks it “failed” with the error details if a request errors.

Setup

  1. Connect your Google Sheets OAuth2 credentials and replace YOUR_GOOGLE_SHEET_ID (and confirm the target sheet/tab) in the read and update steps.
  2. Create a Meta app/access tokens with permissions to post to your Instagram Business account and Facebook Page, then replace YOUR_IG_ACCOUNT_ID, YOUR_FB_PAGE_ID, YOUR_META_ACCESS_TOKEN, and YOUR_FB_PAGE_ACCESS_TOKEN.
  3. Connect your LinkedIn OAuth2 credentials and replace YOUR_LINKEDIN_PERSON_ID for the account that should publish the post.
  4. If you want branded image overlays, upload your base images to Cloudinary, set YOUR_CLOUDINARY_CLOUD, and update the transformation overlay references (logo/text) used to generate the final image URL.
  5. Ensure your Google Sheet includes the expected columns (at least scheduled_date, status, format, image_source_url, caption_fr, hashtags, and a unique post_id) and uses “pending/posted/failed” statuses.
