Automating Image Uploads to Facebook Page using Python and Facebook Graph API

In this article, we’ll explore how to automate the process of uploading images to a Facebook page using Python and the Facebook Graph API. Whether you want to share a single image or multiple images in a single post, this guide will walk you through the steps.

Prerequisites

Before we get started, make sure you have the following:

• A Facebook Developer account
• An App created on the Facebook Developer portal
• App ID and App Secret
• Page ID and Page Access Token

Note : I’m assuming you’re already familiar with the developer portal and tasks like creating an app or generating a page access token. However, if you’re not acquainted with these processes, feel free to reach out — I’d be more than happy to assist you through separate articles.

Setup

1. Install Required Libraries

pip install requests Pillow

2. Facebook Graph API Access

• Obtain your Page Access Token.
• Retrieve your Page ID.

Uploading a Single Image

Now, you need to create a function called post_single_photo. This function is crafted to simplify the process of uploading a single image to a specified Facebook page using the Facebook Graph API. It accepts crucial parameters, including the target page's ID (page_id), the page's access token (page_access_token), an optional message to accompany the photo (message), and the specific URL of the photo to be uploaded (photo_url). Refer to the Python code below for details.

import requests

def post_single_photo(page_id, page_access_token, message, photo_url):
    url = f"https://graph.facebook.com/v13.0/{page_id}/photos"
    params = {
        'access_token': page_access_token,
        'message': message,
        'url': photo_url,
    }

    try:
        response = requests.post(url, params=params)
        result = response.json()

        if 'id' in result:
            print(f"Photo posted successfully. Post ID: {result['id']}")
        else:
            print(f"Error posting photo: {result}")

    except requests.exceptions.RequestException as e:
        print(f"Request error: {e}")

# Replace with your actual values

page_id = 'YOUR_PAGE_ID'
page_access_token = 'YOUR_ACCESS_TOKEN'
message = 'Your message goes here'
photo_url = 'https://example.com/your-photo.jpg'

post_single_photo(page_id, page_access_token, message, photo_url)

Uploading Multiple Images Using Scheduling Posts with Unpublished Photos

Now, you need to follow a series of steps where you first upload photos with the published state set to false. Afterward, obtain the IDs of the unpublished photos and use those IDs to schedule a post to the /me/feed endpoint. Please refer to the Python code provided below for guidance.

import requests

def schedule_posts_with_unpublished_photos(page_id, page_access_token, message, photo_urls):
    # Step 1: Upload photos with published state set to false
    photo_ids = []
    for photo_url in photo_urls:
        upload_url = f'https://graph.facebook.com/v13.0/{page_id}/photos'
        params = {
            'access_token': page_access_token,
            'published': 'false',
            'url': photo_url,
        }

        try:
            response = requests.post(upload_url, params=params)
            result = response.json()

            if 'id' in result:
                photo_ids.append(result['id'])
            else:
                print(f"Error uploading photo: {result}")

        except requests.exceptions.RequestException as e:
            print(f"Request error: {e}")

    # Step 2: Use the IDs of unpublished photos to schedule a post
    url = f'https://graph.facebook.com/v13.0/me/feed'
    params = {
        'access_token': page_access_token,
        'message': message,
    }

    for photo_id in photo_ids:
        params[f'attached_media[{photo_id}]'] = f'{{"media_fbid":"{photo_id}"}}'

    try:
        response = requests.post(url, params=params)
        result = response.json()

        if 'id' in result:
            print(f"Post scheduled successfully. Post ID: {result['id']}")
        else:
            print(f"Error scheduling post: {result}")

    except requests.exceptions.RequestException as e:
        print(f"Request error: {e}")

# Replace with your actual values

page_id = 'YOUR_PAGE_ID'
page_access_token = 'YOUR_ACCESS_TOKEN'
message = 'Your message goes here'
photo_urls = [
    'https://example.com/photo1.jpg',
    'https://example.com/photo2.jpg',
]

schedule_posts_with_unpublished_photos(page_id, page_access_token, message, photo_urls)
