<h2>Prerequisites</h2>
|
|
<p>Before you begin, ensure you have:</p>
|
|
<ul>
|
|
<li>A Facebook account with admin access to the Page(s) you want to post to</li>
|
|
<li>Basic understanding of HTTP requests and APIs</li>
|
|
<li>A development environment (code editor, terminal, etc.)</li>
|
|
<li>Node.js or similar environment for making API requests</li>
|
|
</ul>

<h2>Setting Up a Facebook App</h2>
|
|
|
|
<h3>Step 1: Create a Facebook Developer Account</h3>
|
|
<ol>
|
|
<li>Go to <a href="https://developers.facebook.com/" target="_blank">Facebook for Developers</a></li>
|
|
<li>Click "Get Started" and follow the prompts to create a developer account</li>
|
|
<li>Accept the developer terms and conditions</li>
|
|
</ol>
|
|
|
|
<h3>Step 2: Create a New App</h3>
|
|
<ol>
|
|
<li>In the Facebook Developer Dashboard, click "Create App"</li>
|
|
<li>Select "None" as the app type (for custom integrations)</li>
|
|
<li>Enter your app name and contact email</li>
|
|
<li>Click "Create App ID"</li>
|
|
</ol>
|
|
|
|
<h3>Step 3: Configure Basic Settings</h3>
|
|
<ol>
|
|
<li>Go to "Settings" > "Basic" in your app dashboard</li>
|
|
<li>Fill in basic information:
|
|
<ul>
|
|
<li>Display Name</li>
|
|
<li>Contact Email</li>
|
|
<li>App Domains (if applicable)</li>
|
|
<li>Privacy Policy URL</li>
|
|
<li>Terms of Service URL</li>
|
|
</ul>
|
|
</li>
|
|
<li>Click "Save Changes"</li>
|
|
</ol>
|
|
</section>
|
|
|
|
<section id="permissions">
|
|
<h2>Getting Required Permissions</h2>
|
|
|
|
<h3>Step 4: Add Facebook Login Product</h3>
|
|
<ol>
|
|
<li>In your app dashboard, go to "Products" > "Add Product"</li>
|
|
<li>Click "Set Up" for Facebook Login</li>
|
|
<li>Select "Web" as the platform</li>
|
|
<li>Enter your site URL (can be localhost for development)</li>
|
|
<li>Click "Save"</li>
|
|
</ol>
|
|
|
|
<h3>Step 5: Request Required Permissions</h3>
|
|
<p>For posting to Pages, you'll need:</p>
|
|
<ul>
|
|
<li><code>pages_manage_posts</code> - Manage posts on Pages</li>
|
|
<li><code>pages_read_engagement</code> - Read Page content</li>
|
|
<li><code>publish_pages</code> - Publish content to Pages</li>
|
|
</ul>
|
|
<p>Add these to your app's permissions in the Facebook Login settings.</p>
|
|
</section>
|
|
|
|
<section id="tokens">
|
|
<h2>Generating Access Tokens</h2>
|
|
|
|
<h3>Step 6: Get User Access Token</h3>
|
|
<p>Use the Facebook Login dialog with the required permissions:</p>
|
|
<div class="code-block">
|
|
// Example using Facebook JavaScript SDK
|
|
FB.login(function(response) {
|
|
if (response.authResponse) {
|
|
console.log('Access Token:', response.authResponse.accessToken);
|
|
}
|
|
}, {scope: 'pages_manage_posts,pages_read_engagement,publish_pages'});
|
|
</div>
|
|
|
|
<h3>Step 7: Get Page Access Token</h3>
|
|
<ol>
|
|
<li>First, get the user's Pages:
|
|
<div class="code-block">
|
|
GET https://graph.facebook.com/v12.0/me/accounts?access_token={user-access-token}
|
|
</div>
|
|
</li>
|
|
<li>From the response, find your Page and use its access token</li>
|
|
</ol>
|
|
|
|
<h3>Step 8: Get Long-Lived Access Token</h3>
|
|
<p>Exchange short-lived tokens for long-lived ones:</p>
|
|
<div class="code-block">
|
|
GET https://graph.facebook.com/v12.0/oauth/access_token?
|
|
grant_type=fb_exchange_token&
|
|
client_id={app-id}&
|
|
client_secret={app-secret}&
|
|
fb_exchange_token={short-lived-token}
|
|
</div>
|
|
</section>
|
|
|
|
<section id="api-requests">
|
|
<h2>Making API Requests</h2>
|
|
|
|
<h3>Step 9: Basic API Request Structure</h3>
|
|
<p>Facebook API requests follow this pattern:</p>
|
|
<div class="code-block">
|
|
POST https://graph.facebook.com/v12.0/{page-id}/feed
|
|
?message={your-message}
|
|
&access_token={page-access-token}
|
|
</div>
|
|
|
|
<h3>Step 10: Using Different HTTP Methods</h3>
|
|
<ul>
|
|
<li><code>GET</code> - Retrieve data</li>
|
|
<li><code>POST</code> - Create new content</li>
|
|
<li><code>DELETE</code> - Remove content</li>
|
|
<li><code>PUT</code> - Update existing content</li>
|
|
</ul>

|
<h2>Posting to Pages</h2>
|
|
|
|
<h3>Step 11: Simple Text Post</h3>
|
|
<div class="code-block">
|
|
POST https://graph.facebook.com/v12.0/{page-id}/feed
|
|
?message=Hello%20World!
|
|
&access_token={page-access-token}
|
|
</div>
|
|
|
|
<h3>Step 12: Post with Link</h3>
|
|
<div class="code-block">
|
|
POST https://graph.facebook.com/v12.0/{page-id}/feed
|
|
?message=Check%20out%20this%20link
|
|
&link=https://example.com
|
|
&access_token={page-access-token}
|
|
</div>
|
|
|
|
<h3>Step 13: Scheduled Post</h3>
|
|
<div class="code-block">
|
|
POST https://graph.facebook.com/v12.0/{page-id}/feed
|
|
?message=Scheduled%20post
|
|
&published=false
|
|
&scheduled_publish_time=1633046000
|

&access_token={page-access-token}

<section id="post-types">
|
|
<h2>Handling Different Post Types</h2>
|
|
|
|
<h3>Step 14: Photo Posts</h3>
|
|
<div class="code-block">
|
|
POST https://graph.facebook.com/v12.0/{page-id}/photos
|
|
?url={image-url}
|
|
&caption=Photo%20caption
|
|
&access_token={page-access-token}

<h3>Step 15: Video Posts</h3>
|
|
<div class="code-block">
|
|
POST https://graph.facebook.com/v12.0/{page-id}/videos
|
|
?source={video-url}
|
|
&description=Video%20description
|
|
&access_token={page-access-token}
|
|
</div>
|
|
|
|
<h3>Step 16: Album Posts</h3>
|
|
<div class="code-block">
|
|
// First create album
|
|
POST https://graph.facebook.com/v12.0/{page-id}/albums
|
|
?name=Album%20Name
|
|
&access_token={page-access-token}

|
<section id="error-handling">
|
|
<h2>Error Handling and Best Practices</h2>
|
|
|
|
<h3>Step 17: Error Handling</h3>
|
|
<div class="code-block">
|
|
// Example error handling
|
|
try {
|
|
const response = await fetch(facebookApiUrl, {
|
|
method: 'POST',
|
|
body: formData
|
|
});
|
|
|
|
if (!response.ok) {
|
|
const error = await response.json();
|
|
console.error('Facebook API Error:', error);
|
|
// Handle specific error codes
|
|
}
|
|
} catch (error) {
|
|
console.error('Network error:', error);
|
|
}
|
|
</div>
|
|
|
|
<h3>Step 18: Best Practices</h3>
|
|
<ul>
|
|
<li>Always use HTTPS for API requests</li>
|
|
<li>Store access tokens securely</li>
|
|
<li>Implement token refresh logic</li>
|
|
<li>Handle rate limits gracefully</li>
|
|
<li>Validate all user input</li>
|
|
<li>Use proper error handling</li>
|
|
</ul>
|
|
</section>
|
|
|
|
<section id="rate-limits">
|
|
<h2>Rate Limits and API Usage</h2>
|
|
|
|
<h3>Step 19: Understanding Rate Limits</h3>
|
|
<ul>
|
|
<li>Facebook API has strict rate limits</li>
|
|
<li>Limits vary by endpoint and app type</li>
|
|
<li>Check headers for rate limit information:
|
|
<ul>
|
|
<li><code>X-Business-Use-Case-Usage</code></li>
|
|
<li><code>X-Ad-Account-Usage</code></li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
|
|
<h3>Step 20: Monitoring API Usage</h3>
|
|
<div class="code-block">
|
|
GET https://graph.facebook.com/v12.0/{app-id}/application
|
|
?fields=restrictions
|
|
&access_token={app-access-token}
|
|
</div>
|
|
</section>
|
|
|
|
<section id="troubleshooting">
|
|
<h2>Troubleshooting</h2>
|
|
|
|
<h3>Common Issues and Solutions</h3>
|
|
<ol>
|
|
<li><strong>Permission Errors</strong>: Ensure you have all required permissions</li>
|
|
<li><strong>Token Expiration</strong>: Use long-lived tokens and implement refresh logic</li>
|
|
<li><strong>Rate Limits</strong>: Implement exponential backoff for retries</li>
|
|
<li><strong>API Versioning</strong>: Always specify API version in URLs</li>
|
|
<li><strong>App Review</strong>: Some permissions require Facebook review</li>
|
|
</ol>
|
|
|
|
<h3>Debugging Tools</h3>
|
|
<ul>
|
|
<li>Facebook Graph API Explorer</li>
|
|
<li>Facebook Developer Debugger</li>
|
|
<li>Browser developer tools for network inspection</li>
|
|
</ul>
|
|
|
|
<div class="note">
|
|
<strong>Note:</strong> Always refer to the official Facebook documentation for the most up-to-date information and API changes.
|
|
</div>
|
|
|
|
<div class="warning">
|
|
<strong>Security Warning:</strong> Never expose access tokens in client-side code. Use server-side authentication and implement proper token storage.
