The MonetizationEvent DOM events provide information about payments sent to WM receivers.

The monetization event fires when a WM agent successfully creates an outgoing payment request at the WM provider. There’s no guarantee that any payments will follow or, if they do, how often or how large the payments will be.

By listening for monetization events, you can use the returned details to verify the receipt of a payment. You can then choose to have the page programmatically respond to successful payments. For example, you could remove ads or provide access to exclusive content.
