In this post, we will see how to post to a subreddit using the PRAW wrapper for the Reddit API.

For this tutorial you will need:

  1. Have Python Installed
  2. Have your Reddit API credentials

If you know nothing about Python, make sure that you start by reading the complete guide on Python for SEO.

Be Smart and Read this Important Note

I love Reddit and I dont want you to spam my favourite subs.

If you have never posted to Reddit before, it is not the right way to start by automating it with the API. The community will ban you.

That being said.

I created a subreddit to help SEOs learn how to make bots in a safe environment, without spamming Reddit, or getting you banned by moderators.

I give you full permission to use this subreddit to make your tests, please use it.

Getting Started

The first need that you will need to do is to install and load the required packages.

Open the Terminal and type in:

$ pip install praw
$ pip install json
$ pip install requests

In your python script, load the packages

import json
import praw
import requests

Read the Credential File

Here, we have created the client_secrets.json file in the previous post “Get Reddit API Credentials with PRAW“.

We need to read the file.

credentials = 'client_secrets.json'

with open(credentials) as f:
    creds = json.load(f)

Authenticate the Reddit API

To authenticate with PRAW, we will use the praw.Reddit() function.

Add the parameters from the creds variable.

reddit = praw.Reddit(client_id=creds['client_id'],
                     client_secret=creds['client_secret'],
                     user_agent=creds['user_agent'],
                     redirect_uri=creds['redirect_uri'],
                     refresh_token=creds['refresh_token'])

Make Your Post to a Subreddit

Now the interesting stuff.

Let’s make a simple text post to the Subreddit that I created.

subr = 'pythonsandlot' # Choose your subreddit

subreddit = reddit.subreddit(subr) # Initialize the subreddit to a variable

title = 'Just Made My first Post on Reddit Using Python.'

selftext = '''

Run the Function

subreddit.submit(title,selftext=selftext)

Success!

Full Code

import json
import praw
import requests

subr = 'pythonsandlot'
credentials = 'client_secrets.json'

with open(credentials) as f:
    creds = json.load(f)

reddit = praw.Reddit(client_id=creds['client_id'],
                     client_secret=creds['client_secret'],
                     user_agent=creds['user_agent'],
                     redirect_uri=creds['redirect_uri'],
                     refresh_token=creds['refresh_token'])

subreddit = reddit.subreddit(subr)

title = 'Just Made My first Post on Reddit Using Python.'
selftext = '''
