n8n

Automate social media posting across 14+ platforms using the official Late node for n8n. No HTTP configuration needed — the node handles authentication, request formatting, and response parsing.

Quick Reference

Available Operations

Setup

npm install n8n-nodes-late

Create a Post

1. Add a Late node to your workflow
2. Set Resource to Posts
3. Set Operation to the target platform (e.g., Add Post to Twitter/X)
4. Select your Profile and Social Account from the dropdowns
5. Enter your post Content
6. Optionally set a Scheduled Date for future publishing

The node handles all the API formatting — just fill in the fields.

Platform-Specific Operations

Each platform has its own operation with relevant fields:

Using Dynamic Data

Map fields from previous nodes directly into the Late node fields using n8n expressions:

• Content: {{ $json.postText }} — from a Google Sheets, RSS, or Code node
• Scheduled Date: {{ $json.publishDate }} — ISO 8601 timestamp
• Media URLs: {{ $json.imageUrl }} — from a media source

Schedule a Post

Set the Scheduled Date field to a future timestamp. The post will be queued and published at that time.

To compute the date dynamically, use a Code node before the Late node:

const tomorrow = new Date();
tomorrow.setDate(tomorrow.getDate() + 1);
tomorrow.setHours(9, 0, 0, 0);

return [{ json: { scheduledFor: tomorrow.toISOString() } }];

Then map {{ $json.scheduledFor }} into the Late node's Scheduled Date field.

Upload Media

For files under 4MB:

1. Set Resource to Media
2. Set Operation to Upload
3. Provide the file from a previous node (e.g., HTTP Request, Google Drive, or Read Binary File)

For files over 4MB, use the Presign operation first to get a pre-signed upload URL, upload the file, then reference the media URL when creating a post.

Webhooks

Set up real-time notifications for post and account events:

1. Add a Late node with Resource → Webhooks
2. Configure the webhook URL (your n8n webhook endpoint)
3. Select the events you want to receive

Available events:

Use a Webhook trigger node to receive these events and trigger follow-up actions (e.g., send a Slack notification on failure).

Workflow Examples

Scheduled Daily Posting from Google Sheets

1. Schedule Trigger → Run every day at 9:00 AM
2. Google Sheets → Read the next row from your content calendar
3. Late → Create post with the row's content, platform, and optional media

RSS Feed to Social Media

1. Schedule Trigger → Check every hour
2. RSS Feed Read → Read your blog RSS feed
3. IF → Check if there are new items
4. Late → Post new articles to Twitter/X and LinkedIn

AI Content Generation Pipeline

1. Schedule Trigger → Run daily
2. HTTP Request → Fetch trending topics or RSS items
3. OpenAI → Generate platform-optimized post content
4. Late → Post to multiple platforms with tailored content

Error Handling

Retry on Failure

On the Late node, go to Settings → Retry on Fail:

Webhook Monitoring

Set up a webhook for post.failed events to get notified instantly when a post fails to publish. Combine with a Slack or email node for alerts.

Error Workflow

Set up an Error Workflow in your workflow settings:

1. Create a separate workflow with an Error Trigger node
2. Add notification actions (email, Slack, etc.)
3. In your main workflow, go to Settings → Error Workflow and select it

Rate Limits

The Late node respects the same rate limits as direct API calls. For high-volume workflows, space out executions using the Schedule Trigger interval or add Wait nodes between batches.
