Your token stays with you
The request goes from this page to graph.facebook.com and nowhere else; Trakero never receives the token. It's in the request body, never in a URL.
Meta event tester
Check that your pixel id and access token work before you connect a server. The event goes from this browser to Meta with your test event code, so it shows up under Test events and never in your live data.

- No sign-up
Fill in the pixel id, access token and test event code.
How it works
Always a test event
The tool won't send without a test event code, so Meta shows the event in Events Manager → Test events and doesn't count it as a real conversion.
Errors, explained
An invalid token, a wrong pixel id or a missing permission each get a plain explanation and the step that fixes it.
Questions
Platform rules from Meta: Conversions API, using the API and test events, Meta: Server event parameters.
Where do I find the test event code?
In Events Manager, open your dataset and the Test events tab. The code (like TEST12345) is shown next to “Test server events”.
The tester says received, but nothing shows up. Why?
Test events usually appear within a minute. Check you are looking at the same dataset id, and that the Test events tab shows server events.
Do I need this with Trakero?
No: Trakero sends a test event from the dashboard when you connect Meta. This tool is for checking a token or an existing setup.
Let Trakero do this for every order
Trakero captures click ids, hashes customer data and sends each purchase once to Meta, TikTok, GA4 and more from your server, so ad blockers and Safari can't lose it.
