Publish a POST to Facebook Board Using Facebook API with Python

Tiempo de lectura: 3 minutos

Hello, today we are going to learn how we can publish

Publishing a post on your Facebook page using a Python bot involves interacting with the Facebook API. Here are the general steps you should follow:

Set up an application on Facebook:

Go to the Facebook Developer page (https://developers.facebook.com/).
Create a new application.
Configure the application and obtain API credentials, such as the application ID and access token.

Here’s a complete tutorial on how to create an app for Facebook: https://devcodelight.com/?p=6087

Install Python libraries:

Make sure you have the necessary libraries installed, such as requests and facebook-sdk. You can install them using pip:

   pip install requests
   pip install facebook-sdk

Authenticate with the Facebook API:

Use the API credentials to authenticate with the Facebook API. You can obtain a valid access token by following the Facebook authentication documentation.

To obtain the access token, you can follow this tutorial: https://devcodelight.com/?p=6129

Post to your page:

Use the access token and the facebook-sdk library to post to your page. Here’s an example of code:

import facebook

# Set up your access token
token = 'YOUR_ACCESS_TOKEN'

# Create a Facebook Graph API instance
graph = facebook.GraphAPI(access_token=token, version="X.X")  # Replace "X.X" with the API version you want to use.

# Define the message you want to post
message = "Hello, Facebook!"

# Post to your page
try:
    graph.put_object(parent_object='me', connection_name='feed', message=message)
    print("Successful post on your Facebook page.")
except facebook.GraphAPIError as e:
    print(f"Error posting to your Facebook page: {e}")

Replace 'YOUR_ACCESS_TOKEN' with the access token you obtained in step 3 and modify the message as needed. You can also customize other post parameters according to the Facebook API documentation.

Replace X.X with the version of the Facebook API you want to use, in this case, it’s 17.0

Make sure your app has the necessary permissions to post to your Facebook page. You can configure these permissions in your app settings in the Facebook Developer Dashboard.

If we want to do it without using libraries, we can use this code:

import os
from dotenv import load_dotenv
import requests

def post_to_facebook(message, link):
    load_dotenv()
    FACEBOOK_ACCESS_TOKEN = "ACCESS_TOKEN"
    PAGE_ID = "PAGE_ID"  # Replace this with your page's ID

    # Post Content as Text
    msg = "hi buddy"
    post_url = 'https://graph.facebook.com/{}/feed'.format(PAGE_ID)
    payload = {
    "message": msg,
    "access_token": FACEBOOK_ACCESS_TOKEN
    }
    r = requests.post(post_url, data=payload)
    print(r.text)

    return True

*To obtain the PAGE_ID, we have to do the following:
