How to use the Meta Conversions API Generator
- Enter your pixel ID; create an access token in Events Manager → Settings → Conversions API.
- Pick the event and parameters, and a test customer email to see the hashing.
- Add the test event code to see it in Test events.
- Copy the Node.js, curl, PHP or Python request; send the same event ID from the browser pixel.
Why send events from the server?
Browser pixels miss conversions blocked by ad blockers, browsers and lost cookies. The Conversions API sends them from your server, matched by hashed email, phone, IP and the _fbp cookie. Most setups send both and let Meta deduplicate with the shared event_id. Keep the access token server-side only.

Frequently asked questions
How does Meta deduplicate pixel and server events?
By event_name plus event_id (eventID in the pixel). Send the same pair from both within 48 hours and Meta keeps one.
Which API version should I use?
The latest Graph API version listed in Meta’s changelog — older versions stop working about two years after release. Change the version field to match.
What does action_source mean?
Where the conversion happened: website for online orders, physical_store for in-store sales, system_generated for things like renewals.
Can I install Meta Conversions API Generator as a web app and use it offline?
Yes. Meta Conversions API Generator is an installable web app (PWA) — installed from your browser, not downloaded from an app store. Click Install app at the top of this page in Chrome or Edge (Windows, macOS, Linux, ChromeOS) or on Android, use Share → Add to Home Screen on iPhone and iPad, or File → Add to Dock in Safari 17+ on a Mac. It then opens in its own window with its own icon, and because it runs entirely in your browser it keeps working offline. Firefox on desktop can’t install web apps. How installing works.
