Automate Twitter Posts with n8n Form Trigger & API

Streamline your Twitter content publishing with this powerful n8n workflow that transforms form submissions into published tweets. Whether you're posting text-only updates or sharing images, this automation handles the entire process from form input to live tweet URL generation.

What this workflow does

This comprehensive Twitter automation workflow processes form submissions through a complete posting pipeline:

• Captures form data with required post text and optional image uploads via n8n Form trigger
• Validates and normalizes inputs, enforcing supported image formats (JPG, PNG, WEBP, GIF) and size restrictions
• Creates text-only posts directly through X API v2 POST /2/tweets endpoint when no media is included
• Handles media uploads by first posting to POST /2/media/upload, extracting media IDs, then creating tweets with attached images
• Returns structured success responses with tweet IDs and URLs, or detailed error messages for troubleshooting

Use cases

Perfect for automation engineers and SaaS operators who need reliable Twitter posting solutions:

• Content creators scheduling posts through custom forms without third-party tools
• Marketing teams enabling non-technical staff to publish branded content with images
• SaaS operators building customer-facing social media posting features
• Agencies managing multiple Twitter accounts through centralized form interfaces
