📱 Schedule X posts, threads, images and polls with webhooks

💡 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 receives webhook requests from a content calendar and uses the X API v2 to publish text posts, threads, image/video posts, and polls, as well as delete existing posts and run a credential connection test, returning a consistent JSON success/error response to the caller.

How it works

1. Receives a POST webhook request containing a request type and payload from the scheduling calendar.
2. Routes the request by body.type to create a single X post, publish an X thread, delete an X post, run an X credential test, or return an unknown-type error.
3. For single posts, validates the payload (including blocking invalid polls or mixed poll-plus-media), then posts either a text-only tweet, a poll tweet, or a tweet with uploaded media.
4. For media posts, uploads base64-encoded images/videos to X using INIT/APPEND/FINALIZE, polls X until processing completes when required, and then publishes the tweet with the returned media_ids.
5. For threads, posts the first tweet, then posts each subsequent tweet as a reply to the previous tweet ID to keep the chain intact, and returns the list of tweet IDs and URLs.
6. For delete requests and connection tests, calls X’s delete-tweet endpoint or GET /2/users/me and returns a structured success or error payload.
7. Responds to the webhook with a standardized JSON result including success, IDs/URLs when available, or an error code and message.

Setup

1. Create an X Developer app with OAuth 2.0 user-context access and required permissions for posting and media uploads.
2. In n8n, add an OAuth2 API credential for X with scopes tweet.read tweet.write users.read offline.access media.write and select it on all X HTTP Request steps.
3. Activate the workflow, copy the Webhook Trigger Production URL, and configure your content calendar (for example, the included index.html) to send POST requests to that URL with the expected body.type values.

Requirements

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

Additional info

This workflow is tested and works with the include index.html calendar frontend ui.
