Logging Meta Events

Send analytics-safe custom events from the website to the native Meta App Events SDK.

Before you start

Define the event
Choose a stable Meta-compatible event name and a small parameter object.
Log through the helper
Call webtoapp.logMetaEvent(name, parameters).
Observe the response
Listen for webtoapp:meta-event or generic onmessage.
Verify in Meta tools
Use Events Manager test events and confirm the correct app receives data.

webtoapp.logMetaEvent("order_placed", {
  order_amount: 117.5,
  currency: "USD"
});
