Twitter has taken the world by storm with its concept of tweets, ease of use and platform integration. With its more than 300 million users, Twitter is very popular and is available on almost all platforms.

The concept of a tweet is very similar to the older SMS (Short Message Service) but without some of its limitations. Hashtags and images can also be used. Tweets can be send globally to multiple recipients at the same time and the costing structure is integrated into data usage.

Reasons for posting to Twitter from a Raspberryr Pi range from a bit of fun, to building an follower audiance, to sending information to a easily accessible platform. Other ways of sending messages from a Raspberry Pi include emails and SMSs. Various APIs and collected data from sensors are also popularly tweeted.


For this post, a fully installed Raspberry Pi with Raspbian and a connection to the internet was used. Without a connected keyboard and screen, PuTTY and/or WinSCP can be used to do the testing and coding. On the social media side, access to a verified Twitter account with a working cell phone number was required.

Creating and configuring a Twitter App

To be able to post to Twitter from the Raspberry Pi, access to Twitter through their API will be required. For this, a Twitter App needs to be created.

To create a new Twitter App, open the Twitter Application Manager.

Create a new Twitter Ppp

After the app is created, set the access level to both read and write before generating an access token. The following information should now be available and noted down:

  • Consumer Key (API Key)
  • Consumer Secret (API Secret)
  • Access Token
  • Access Token Secret

For a more thorough guide on this process, also see Twitter App settings to access the API.

Posting to Twitter using Python

To post to Twitter from a Raspberry Pi, additional Python libraries will be required. There are probably more, but this process was tested using Tweepy and Twython. Both these libraries are easy to install and fairly easy to use. Both Tweepy and Twython are installed using pip. The following terminal command can be used to install and update pip:

sudo apt-get install python-pip
sudo pip install --upgrade pip --index-url=


Tweepy is a very popular, easy-to-use, Python library for accessing the Twitter API. Although it is somewhat more complex to use than Twython (see below), it does have the advantage of being able to tweet images as well as text. After installing pip, Tweepy is installed by using the following terminal command:

sudo pip install tweepy

To see if Tweepy has been installed, make sure it is on the list generated by:

pip list

There might be some difficulties installing Tweepy (and other pip packages) starting from pip version 10. If this is the case, pip needs to be downgraded again before trying to install Tweepy again. Pip can be downgraded using:

sudo -H pip install pip==8.1.1

Tweepy can be uninstalled using:

sudo pip uninstall tweepy

To use Tweepy, create a python file in a desired directory:


and add and adapt the following code to it before saving (this is the original script posted by Nikhil from

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import tweepy

def get_api(cfg):
auth = tweepy.OAuthHandler(cfg['consumer_key'], cfg['consumer_secret'])
auth.set_access_token(cfg['access_token'], cfg['access_token_secret'])
return tweepy.API(auth)

def main():
# Fill in the values noted in step 2 here
cfg = {
"consumer_key" : "VALUE",
"consumer_secret" : "VALUE",
"access_token" : "VALUE",
"access_token_secret" : "VALUE"

api = get_api(cfg)
tweet = "Hello, world!" # tweet text (140 chars. max.)
status = api.update_status(status=tweet)

if __name__ == "__main__":

The values of VALUE and tweet should be replaced with your own (keep the quotation marks). The following terminal command can be used to run the script:


By modifying the code as follows, an image can also be tweeted:

api = get_api(cfg)
tweet = "Hello, world!" # tweet text (140 chars. max.)
image = "/home/pi/image.jpg" # image file destination
#status = api.update_status(status=tweet)
status = api.update_with_media(image, tweet)


Twython is a pure Python wrapper for the Twitter API. It will work for Python 2.6+ and Python 3. Apart from tweeting, it can also do a few other things using the Twitter API. After installing pip, Twython is installed by using the following terminal command:

sudo pip install twython

To use Twython, create a Python file in a desired directory:


and add and adapt the following code to it before saving:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import sys
from twython import Twython

consumer_key = "VALUE"
consumer_secret = "VALUE"
access_token = "VALUE"
access_token_secret = "VALUE"

api = Twython(consumer_key,consumer_secret,access_token,access_token_secret)

The values of VALUE should be replaced with your own (keep the quotation marks). The following terminal command can be used to tweet:

python "Hello, world!"

This makes it easy to tweet directly from the terminal, a Bash script or another Python script.

Additional notes

Run Tweepy from a Bash script

Twython is straight forward to run from Bash, but Tweepy can be a bit more challenging. With the code below, the Bash script will forward the tweet and image directory to the modified Python script.


# Tweet (max. 140 characters)
tweet="Hello, world!" # tweet text

# Absolute directory and full file name of image
python /home/pi/ "$full_image_path;$tweet" # note that image and tweet is separated with a ";" for Python to work with

Include the following code in the top of modified Python script to be able to handle the Bash strings:

import sys

image_plus_tweet = ' '.join(sys.argv[1:]) # image directory and message (after ";")
image = image_plus_tweet.split(";")[0] # strip everything after/including the ";".
tweet = image_plus_tweet.split(';', 1)[-1] # strip everything before/including the ';'.
if image == tweet: # meaning there is no image
   tweet = ""


There are strict Twitter rules against what they consider to be spam. Using third party applications and autoposting might be flagged as spam. Twitter states the following:

“You are ultimately responsible for the actions taken with your account, or by applications associated with your account. Before authorizing a third-party application to access or use your account, make sure you’ve thoroughly investigated the application and understand what it will do. If automated activity on your account violates the Twitter Rules or these Automation Rules, Twitter may take action on your account, including filtering your Tweets from search results or suspending your account.”

In order to prevent Twitter from flagging an account, make sure to use your Twitter account as a human too.
