<p><strong>CapiFlow</strong> sends supported WooCommerce events from your server to Meta’s Conversions API (CAPI) — helping reduce the impact of browser-side tracking limitations like ad blockers, Safari ITP, and Firefox ETP.</p>
<h4>Why Server-Side Tracking Matters</h4>
<p>When the Meta pixel is blocked, event data may not reach Meta — affecting ad optimization. CapiFlow complements the browser pixel by sending events server-side with a matching <code>event_id</code> for deduplication.</p>
<h4>How It Works</h4>
<ol>
<li><strong>Install & Activate</strong> — Setup wizard launches automatically</li>
<li><strong>Enter Pixel ID + Access Token</strong> — From Meta Events Manager</li>
<li><strong>Click Test Connection</strong> — Events start flowing</li>
</ol>
<p>No theme edits. No GTM server container required. No separate server-container subscription needed for the built-in Meta CAPI workflow.</p>
<h4>Core Features</h4>
<p><strong>Server-Side Event Tracking</strong></p>
<ul>
<li>🎯 <strong>7 Standard Events</strong> — Purchase, InitiateCheckout, AddPaymentInfo, AddToCart, ViewContent, Search, PageView</li>
<li>🔄 <strong>Deduplication</strong> — Browser pixel and server events share the same <code>event_id</code> to support Meta’s deduplication</li>
<li>🛡️ <strong>First-Party Event Endpoint</strong> — Browser events can be delivered through your own domain where configured</li>
<li>🔐 <strong>SHA-256 PII Hashing</strong> — Email, phone, name hashed before leaving your server</li>
</ul>
<p><strong>Event Match Quality Support</strong> — <code>fbc</code>, <code>fbp</code>, <code>external_id</code>, client IP, user agent, and hashed customer data (email, phone, name) for logged-in users.</p>
<p><strong>Analytics & Monitoring</strong></p>
<ul>
<li>📈 Dashboard — event breakdown and source attribution</li>
<li>🔍 Debug console — payloads and Meta API responses</li>
<li>🏥 System health — token, queue, connection test</li>
<li>🛒 Cart monitor — abandoned cart summary</li>
</ul>
<p><strong>Data Quality & Control</strong></p>
<ul>
<li>📞 Phone validation at checkout</li>
<li>🔒 COD Purchase gate — hold events until admin confirms</li>
<li>📋 Order metabox and columns — per-order CAPI status</li>
</ul>
<p><strong>Developer Tools</strong></p>
<ul>
<li>🔧 Code injection — GTM, analytics, chat widgets (admin-only)</li>
<li>🪝 Filter hooks — <code>capiflow_proxy_url</code>, <code>capiflow_has_tracking_consent</code></li>
<li>📦 HPOS compatible — WooCommerce High-Performance Order Storage support</li>
<li>⏱️ Action Scheduler queue — async event delivery with retry logic</li>
</ul>

<h4>External Services</h4>

<p><strong>Meta (Facebook) Conversions API</strong></p>
<p>CapiFlow sends WooCommerce event data to the Meta Conversions API via: <code>https://graph.facebook.com/</code></p>
<p>This connection is made from your server to Meta’s servers when a configured tracking event occurs. No data is sent until a valid Pixel ID and Access Token are configured.</p>
<p>Data transmitted includes:</p>
<ul>
<li>Hashed email, phone, first and last name (SHA-256)</li>
<li>Client IP address and Browser User Agent</li>
<li>Meta Click ID (_fbc) and Browser ID (_fbp) cookies</li>
<li>Order total, currency, and event metadata</li>
</ul>
<p>All personal data is SHA-256 hashed before transmission.</p>
<ul>
<li><a href="https://www.facebook.com/terms.php" rel="nofollow ugc">Meta Terms of Service</a></li>
<li><a href="https://www.facebook.com/privacy/policy/" rel="nofollow ugc">Meta Privacy Policy</a></li>
<li><a href="https://developers.facebook.com/terms/" rel="nofollow ugc">Meta Platform Terms</a></li>
</ul>
<p><strong>Meta Pixel JavaScript SDK</strong></p>
<p>This plugin loads the Meta Pixel SDK from: <code>https://connect.facebook.net/en_US/fbevents.js</code></p>
<p>Loaded on frontend pages when a Pixel ID is configured. The SDK is hosted by Meta.</p>

<li><a href="https://www.facebook.com/privacy/policy/" rel="nofollow ugc">Meta Privacy Policy</a></li>
</ul>
<h4>Privacy</h4>
<p>For server-side events, all personal data is SHA-256 hashed before transmission. For browser events, the Meta Pixel SDK handles hashing via Advanced Matching. This plugin does not store raw PII in its own tables. See <a href="https://www.facebook.com/privacy/policy/" rel="nofollow ugc">Meta’s privacy policy</a>.</p>
<h4>Cookies</h4>
<ul>
<li><code>cs_uid</code> — Random visitor identifier for <code>external_id</code> deduplication. 180 days. No PII.</li>
<li><code>_fbc</code> — Meta Click ID. Set by Meta SDK on ad click. CapiFlow reads/extends server-side. 180 days.</li>
<li><code>_fbp</code> — Meta Browser ID. Set by Meta SDK. CapiFlow reads/extends server-side. 180 days.</li>
</ul>
<p>All cookies are first-party and contain no personally identifiable information.</p>
<h4>Data Storage</h4>
<ul>
<li><code>{prefix}_capiflow_events</code> — Queued/sent event payloads. Auto-purged after delivery.</li>
<li><code>{prefix}_capiflow_analytics</code> — Daily aggregated analytics. Auto-purged by retention settings.</li>
<li>Order metadata with <code>_capiflow_</code> prefix. Removed on uninstall if “Keep Data” is disabled.</li>
<li>Logs in <code>wp-content/uploads/capiflow-logs/</code> with <code>.htaccess</code> protection. Auto-cleaned daily.</li>
</ul>
<h4>Consent</h4>
<p>By default, events fire once configured. Enable “Consent Enforcement” in Settings to respect CMP signals for both browser and server events.</p>
<p>Supported CMPs: CookieYes, Complianz, CookieBot, GDPR Cookie Consent. Custom integration via <code>capiflow_has_tracking_consent</code> filter.</p>
<p>When Consent Enforcement is enabled, browser and server-side events are blocked until valid tracking consent is detected.</p>
<p>Store owners are responsible for lawful consent configuration where required by privacy regulations.</p>

<h4>Why use Pixel Cat – Conversion Pixel Manager?</h4>
<p>There are multiple ways to add a Facebook Pixel to your WordPress site.</p>
<p><strong>1. Pasting your Facebook Pixel into your theme</strong><br />
This approach isn’t great for two reasons:<br />
a) If you edit your live site and make a mistake when pasting your Facebook Pixel script into your theme, you could take down your website.<br />
b) If your theme is updated with new features or security fixes, your Facebook Pixel code will be overwritten.</p>
<p><strong>2. Pasting the new Facebook Pixel script into a header/footer script plugin</strong><br />
This is a valid approach, but has some disadvantages. General purposes “header script plugins” aren’t built from the ground-up to support Facebook’s Pixel.</p>
<p>What this means is that :<br />
a) These plugins lack Facebook-specific functionality. There’s no easy way to add Standard Events, Custom Events or Dynamic Events.<br />
b) These plugins will not adapt if Facebook changes their pixel again in the future. Since Pixel Cat is a dedicated Facebook Pixel plugin, we’ll make sure make sure to stay compatible with future changes by Facebook.<br />
c) These plugins usually don’t support hiding your Facebook Pixel from logged-in users.</p>
<p>And, most importantly: with Pixel Cat you can set up Facebook Pixel standard events, without having to write a single line of code.</p>
<p>The bottom line is that Pixel Cat is the best way to add a Facebook Pixel to your WordPress site.</p>
<h4>Does Pixel Cat – Conversion Pixel Manager support the new Facebook Pixel?</h4>
<p>Yes. Pixel Cat is built from the ground up to support the new Facebook Pixel.</p>
<p>If you’re currently using v1.3.5, or later, for the old deprecated Facebook Pixel, and would like to continue doing so, no worries. Pixel Cat – Conversion Pixel Manager will automatically detect your old settings, and will let you continue using the old version of the plugin for this purpose. You can then upgrade to the new pixel at any time.</p>
<h4>Can I hide my Facebook Pixel form logged in users?</h4>
<p>Yes. You can hide your Facebook Pixels from logged in users by going to Settings -> Facebook Pixel Manager.</p>
<h4>Is Pixel Cat – Conversion Pixel Manager easy to translate?</h4>
<p>Yes. Pixel Cat – Facebook Pixel Cat is fully translateable. Please let us know if you’re interested in contributing.</p>
<h4>Do you integrate with WooCommerce</h4>
<p>Yes, our our <a href="https://fatcatapps.com/pixelcat/premium" rel="nofollow ugc">pro plugin</a> makes setting up a Facebook Pixel WooCommerce integration a breeze.
