How to automate posts on a Facebook fan page using backend code?

Backend
1

I’m working on a Facebook app that needs to post content to a fan page automatically. I’m not talking about a personal profile, but a fan page for a business or brand. I’ve been looking at the streamPublish function, but I’m stuck on how to keep the backend code authenticated between different sessions.

I think it has something to do with using a session secret and key, but I can’t find any clear examples. Does anyone know how to set this up? I’m using the official Facebook PHP library.

Here’s a basic code snippet of what I’ve tried:

$fb = new FacebookApp($appId, $appSecret);
$pageToken = 'your_page_access_token';

try {
    $response = $fb->post('/page_id/feed', ['message' => 'Automated post'], $pageToken);
} catch(FacebookException $e) {
    echo 'Error: ' . $e->getMessage();
}

But this doesn’t persist the authentication. Any ideas on how to make this work long-term without manual intervention?

hey there! have you considered using Facebook’s Graph API for this? it might be more reliable for long-term automation. What about setting up a cron job to refresh the access token periodically? that could help maintain authentication. curious to hear if youve explored other PHP libraries or frameworks for social media posting?

Using a long-lived Page Access Token is an effective method for automating posts on a Facebook fan page. You can acquire this token by first obtaining a long-lived User Access Token and exchanging it for a Page Access Token. These tokens are valid for up to 60 days, which reduces the frequency of manual updates.

Storing the token securely in your backend and scheduling a task, such as a cron job, to refresh it before expiration can maintain seamless automation. Utilizing the Graph API endpoint “/PAGE_ID/feed” offers reliable functionality. It is important to handle rate limits, errors, and ensure that your app credentials remain secure over time.

yo LucasPixel23, try grabbing a long-lived page access token instead. those last way longer, like 60 days. then u can use that token in ur code to post without needing to reauthenticate all the time. just remember to refresh it before it expires. also, watch out for rate limits n stuff when posting automatically.
