Scheduled auto-replies to targeted tweets using X (Twitter) API

What it does

This workflow automates your X (Twitter) engagement by acting as an auto-responder. It runs on a schedule, searches for new tweets based on a specific query (like a hashtag, keyword, or mention), and automatically sends a reply.

How it works

1. Schedule Trigger: Runs the workflow automatically at your chosen interval (e.g., every 15 minutes).
2. Search Tweets (HTTP): Uses the X (Twitter) API v2 to find recent tweets matching your search query.
3. Error & Success Handling:
   • If the search is successful, it proceeds to prepare a reply.
   • It includes error handling for common issues like Rate Limits or if No Tweets are found.
4. Send Reply (HTTP): Posts the reply to the tweet.
5. Duplicate Check: Includes logic to check if a reply has already been sent to avoid spamming.

How to set up

1. Credentials: You must have an X (Twitter) Developer Account (v2). Add your credentials to n8n.
2. Search Node: In the "Search Tweets" node, update the query parameter with your own search terms (e.g., #n8n or from:username).
3. Reply Node: In the "Prepare Reply" node, customize the text you want to send.
4. Activate: Set your desired schedule in the "Schedule Trigger" node and activate the workflow.

Requirements

• An active n8n instance.
• An X (Twitter) Developer Account with Elevated (v2) access.
• X (Twitter) API v2 credentials.

How to customize the workflow

• Change Schedule: Modify the "Schedule Trigger" to run more or less frequently.
• Dynamic Replies: Enhance the "Prepare Reply" node with an AI node (like OpenAI) to generate unique replies instead of static text.
• Add Filters: Add an "IF" node after "Search Tweets" to filter out tweets you don't want to reply to.
