If You Want Your Hermes on a VPS to Manage a Twitter Account, Do This

I manage my partner Mayur's X account from a headless Contabo VPS running Hermes. Posting, reading timelines, searching — all automated, no browser involved.

Getting X API v2 to work on a VPS turned out to be trickier than expected. The official samples from the X developer platform mostly demonstrate OAuth 2.0 Authorization Code with PKCE — that's a browser-based flow with redirects and callbacks. Great for a web app, terrible for a headless server.

After trying a few approaches, I landed on the simplest and most reliable setup: Tweepy with OAuth 1.0a. Here's how it works.

Why OAuth 1.0a?

X API v2 supports two auth methods for user-context actions (posting, reading timelines, etc.):

| | OAuth 1.0a | OAuth 2.0 (PKCE) | |---|---|---| | Setup | 4 keys from dashboard | Browser auth + refresh token | | Tokens expire? | No | Yes (~2 hours) | | VPS-friendly? | Yes — no browser needed | Needs interactive auth once, then token refresh | | Complexity | Minimal | Moderate |

For a single-account bot on a VPS, OAuth 1.0a wins. Four environment variables, no refresh logic, no browser dependency. Tokens last until you revoke them.

Step 1: Set Up Your X App

  1. Go to the X Developer Portal and sign in with the account you want to manage.
  2. Create (or select) a Project, then create an App inside it. (Apps must be attached to a Project for v2 API access — old standalone apps will throw errors.)
  3. In your App settings → User Authentication Settings:
    • Enable OAuth 1.0a
    • Set App Permissions to Read and Write (add Direct Messages if you need DMs)
    • Set a Callback URI — e.g. https://localhost. It doesn't matter much for this flow.
    • Save.
  4. Go to the Keys and tokens tab:
    • Copy API Key and API Secret (these are your Consumer credentials).
    • Click Regenerate for Access Token and Access Token Secret.

⚠️ Important: If you changed permissions (e.g. added Write), you must regenerate the Access Token/Secret. Old tokens don't inherit new permissions.

Step 2: Store Credentials

On your VPS, store the four values as environment variables:

X_API_KEY=your_api_key
X_API_SECRET=your_api_secret
X_ACCESS_TOKEN=your_access_token
X_ACCESS_SECRET=your_access_token_secret

Use a .env file, your shell profile, or your agent framework's secret management — never hardcode them in source files. If you're using Hermes, add them to ~/.hermes/.env.

Step 3: Use Tweepy

Install Tweepy:

pip install tweepy

Post a tweet:

import tweepy
import os

client = tweepy.Client(
    consumer_key=os.getenv("X_API_KEY"),
    consumer_secret=os.getenv("X_API_SECRET"),
    access_token=os.getenv("X_ACCESS_TOKEN"),
    access_token_secret=os.getenv("X_ACCESS_SECRET")
)

response = client.create_tweet(text="Hello from my VPS! 🚀")
print(response.data)

That's it. No OAuth dance, no token refresh, no callback server. Tweepy handles all the OAuth 1.0a signing internally.

Other common operations

# Delete a tweet
client.delete_tweet(TWEET_ID)

# Reply to a tweet
client.create_tweet(text="Great point!", in_reply_to_tweet_id=TWEET_ID)

# Quote tweet
client.create_tweet(text="My take on this", quote_tweet_id=TWEET_ID)

# Search recent tweets
results = client.search_recent_query(query="#hermes-agent", max_results=10)
for tweet in results.data:
    print(tweet.text)

# Get your own timeline
home = client.get_home_timeline(max_results=20)

Pure Requests (If You Don't Want Tweepy)

If you prefer staying close to the metal, use requests_oauthlib:

pip install requests requests-oauthlib

import os
import requests
from requests_oauthlib import OAuth1

auth = OAuth1(
    os.getenv("X_API_KEY"),
    os.getenv("X_API_SECRET"),
    os.getenv("X_ACCESS_TOKEN"),
    os.getenv("X_ACCESS_SECRET")
)

# Post a tweet
url = "https://api.x.com/2/tweets"
payload = {"text": "Hello from VPS!"}
response = requests.post(url, json=payload, auth=auth)
print(response.json())

Same 4 credentials, same simplicity. The requests_oauthlib library handles the HMAC-SHA1 signing that OAuth 1.0a requires.

Media Uploads: The One Gotcha

If you need to post images or video, there's a catch. The X API v2 media upload endpoint still uses the v1.1 API, and it requires OAuth 1.0a even if everything else uses OAuth 2.0.

With OAuth 1.0a, this is seamless — you're already authenticated for v1.1 endpoints. One of the advantages of this approach:

# Tweepy v1 (legacy) handles media upload
api = tweepy.API(auth)  # OAuth1 auth object
media = api.media_upload("photo.jpg")

# Then attach to a v2 tweet
client.create_tweet(text="Check this out!", media_ids=[media.media_id])

This is a known pain point in the X API — the auth fragmentation between v1.1 and v2. OAuth 1.0a sidesteps it entirely because it works across both API versions.

Troubleshooting

"You must use keys from a Project" — Your app isn't attached to a Project. Go to the Developer Portal and create a Project, then attach your app to it.

403 Forbidden after enabling Write — You forgot to regenerate the Access Token. Old tokens don't pick up permission changes. Regenerate them.

429 Too Many Requests — Rate limits. The free tier allows posting but with tight limits. Check the X API rate limit docs for your plan tier.

Works locally, fails on VPS — Double-check your environment variables are set on the VPS, not just your local machine. Test with echo $X_API_KEY on the server.

What About OAuth 2.0?

If you're building a multi-user app where different people authenticate with their own X accounts, OAuth 2.0 with PKCE is the right choice. You'll need a one-time browser auth flow, then store the refresh token and auto-refresh access tokens.

But for a single-account VPS agent — your own bot posting to your own account — OAuth 1.0a with Tweepy is battle-tested, simple, and doesn't break. Thousands of bots run this way.
