How to Automatically Comment on X (Twitter) Posts with n8n

Responding to X (formerly Twitter) posts manually can be tedious, especially for professionals and teams needing to scale personalized engagement, support, or outreach. The fast-paced, conversational nature of X means opportunities for engagement are easily missed if you rely on manual processes, and attempting to automate with low-quality bots often leads to detection, unreliable results, or suspended accounts. Limitations of the X API—such as strict rate limits, limited actions, and authentication hurdles—further complicate any scalable automation effort.

With Airtop’s X Post Comment Automation for n8n, you can reliably and securely automate X replies at scale. This automation leverages real browser sessions to safely log in and interact with the X platform as a real user, enabling you to comment on specified posts with fully custom replies. Airtop supports advanced authentication scenarios, including OAuth, 2FA, and Captcha, and seamlessly integrates with n8n for orchestrating larger workflows. The result is a robust solution for social engagement, customer success, or lead gen teams who need to reply in bulk—without sacrificing authenticity or risking bans.

Airtop takes care of navigating to any X post, securely logging in via your Airtop Profile, posting replies you define, and returning success feedback to your n8n workflow—enabling reliable, scalable, and semi-personalized X engagement. Whether you’re managing multiple brands, running campaigns, or automating support, you benefit from high relevance and low risk compared to traditional scrapers or unofficial X bots.
