Successful refund.
accountClosed

object (AccountClosed)

accountClosedAccountTakenOver

object (AccountClosedAccountTakenOver)

The user's account with the integrator has been closed, suspected account take over.

Returning this value will cause the user's instrument to be closed with Google. The user will be forced to add a new instrument by going through the association flow again.
accountClosedFraud

object (AccountClosedFraud)

The user's account held with the integrator has been closed because of fraud.

Returning this value will cause the user's instrument to be closed with Google. The user will be forced to add a new instrument by going through the association flow again.
accountOnHold

object (AccountOnHold)

The user's account is currently on hold and cannot accept the refund, but the user's account may later be able to accept the refund. Google may request another refund in the future, but will do so with a new requestId, so this request should be considered finished.

The refund cannot be processed at the current time, because doing so would cause the user's balance to exceed the maximum allowed amount. Google may request another refund in the future, but will do so with a new requestId, so this request should be considered finished.
refundWindowExceeded

object (RefundWindowExceeded)

The refund cannot be processed because the request is outside of the allowed refund period.

}
Fields
rawResult

object (RawResult)

OPTIONAL: Raw result of this event. Used to help inform Google's risk engine and analytics. In decline code–mapping situations, data is sometimes lost. The integrator can choose to give Google a raw code. For example, a credit card gateway (the integrator) may use this field to communicate to Google the exact decline code that was received from the VISA network. In that case, the scope would be "visa" and the rawCode would be whatever the VISA network returned.

RefundWindowExceeded

The refund cannot be processed because the request is outside of the allowed refund period.
