💡 Pro Tip — Twitter’s API is paid now, which makes simple data pulls expensive. ScraperNode is a community node that scrapes Twitter profiles and posts without needing API access.

Description

Quick overview

This workflow uses an n8n Form trigger and the X (Twitter) API to publish a text-only post or a post with a single uploaded image, then returns a success/error payload including the resulting tweet URL.

How it works

1. Receives a form submission with required post text and an optional image upload.
2. Validates and normalizes the input, enforcing supported image types (JPG/PNG/WEBP/GIF) and size limits.
3. If no image is provided, creates a post on X via the X API v2 POST /2/tweets endpoint.
4. If an image is provided, uploads the media to X via POST /2/media/upload, extracts the returned media ID, and creates the post with that media attached via POST /2/tweets.
5. Returns a success response with the tweet ID and tweet URL, or a structured error message when X returns an API error.

Setup

1. Create an X OAuth2 API credential with user-context scopes tweet.read tweet.write users.read offline.access media.write and apply it to all X HTTP requests in the workflow.
2. Copy the public URL of the n8n form path x-content-scheduler-free and use it to open the “Post to X” form for publishing.
3. (Optional) Run the manual connection test that calls GET /2/users/me to confirm the credential is connected to the correct X account.

Requirements

• x.com api app oauth2 credentials (pay as you go)
