How to automate social media publishing with n8n or Make

Description and use

A repeatable automation pipeline for scheduling social media posts with n8n or Make, using idempotency and retry logic to prevent duplicates and ensure reliable delivery via the PostSider API.

Problem

Automating scheduled social media posts while preventing duplicate posts and ensuring reliable delivery.

Outcome

The pipeline enables scheduled social media publishing with duplicate prevention, idempotency, and retry handling, suitable for both n8n and Make.

Workflow

• Choose a source event (CMS publish, spreadsheet approval, etc.)
• Read one source record and check approval and required fields
• Persist the request and idempotency key
• HTTP Request: create scheduled post
• Store returned post ID
• HTTP Request: read post
• Compare saved fields with the request
• Update source status

Evidence

A CMS event or spreadsheet row can become a scheduled social media post through an HTTP request.

Source

The request example uses PostSider, which I build.

Use a read request to verify authentication and destination
