How does the Google Sheet workflow function?
The Google Sheet workflow manages content with one row per planned post, media links stored directly, action status written back, and support for link-in-caption, first comment, and optional FB/IG story duplicates.
The Google Sheet workflow is the easiest way to manage content for both humans and agents:
- one row per planned post
- media links stored directly in the sheet
- action status written back into the same row
- support for link-in-caption, first comment, and optional FB/IG story duplicates
Start here:
What is the n8n workflow template?
The n8n workflow template reads queued rows from the post tab, resolves media, detects content types, sends posts to POST.devad.io, handles stories, and writes back status to the sheet.
The repo now includes the working n8n template used for:
- reading queued rows from the
posttab - resolving direct links, Google Drive files, and Google Drive folders
- detecting
text,image,video, andcarousel - sending feed posts to POST.devad.io
- optionally sending a separate FB/IG story request
- writing
Action?andlogback into the same sheet row
Important for Google Drive video/file usage:
- after importing the template, open the node
Download Drive Media Asset - set Authentication to
Predefined Credential Type - choose
Google Drive OAuth2 API - select your real Google Drive credential and save the workflow once
This one-time UI save is required because some n8n API/MCP updates do not persist the HTTP Request node’s Drive credential binding.
Start here:
What are the benefits of n8n?
n8n offers lower maintenance with one shared setup node, one-row-per-run safety, and easy adaptation for webhooks or queues.
- lower maintenance than building one branch per platform
- one shared setup node for token, IDs, and defaults
- one-row-per-run safety by default
- easy to adapt for webhook fan-out or queue-based automation
What content types are supported?
Supported content types include text, image, video, carousel, optional FB/IG first comment, and optional FB/IG story duplicate.
textimagevideocarousel- optional FB/IG first comment behavior
- optional FB/IG story duplicate behavior
Which channels are supported in the reference flow?
The current reference flow supports TikTok, Instagram, Facebook, LinkedIn, YouTube, Pinterest, Telegram, Tumblr, and Google Business Profile, depending on account and media types.
- TikTok
- YouTube
- Telegram
- Tumblr
- Google Business Profile
Channel behavior still depends on the account type, media type, and the capabilities available in your POST.devad.io integrations.
What is the recommended order for new users?
New users should read the Google Sheet guide first if preferring sheet workflow, then n8n guide, import and configure, test simple rows before advanced features.
- Read the Google Sheet guide if you want the sheet-first workflow.
- Read the n8n guide if you want the automation-first workflow.
- Import the n8n workflow JSON and relink Google credentials.
- Manually bind the Google Drive credential in
Download Drive Media Asset. - Add your POST.devad.io token and integration IDs.
- Test one Telegram or single-image row first.
- Test one Google Drive video row.
- Only then enable optional story or webhook branches.
What are the notes about private values?
This repo is public-safe with no private API tokens, integration IDs, or Google credentials committed; use placeholders and fill in live environments.
This repo is intended to be public-safe:
- no private API tokens should be committed
- no personal integration IDs should be committed
- no private Google credentials should be committed
Use placeholder values in public templates and fill real values only inside your own live environment.
