    object (ResponseHeader)
  },

Fields
responseHeader

REQUIRED: Common header for all responses.
paymentIntegratorRefundId

string

OPTIONAL: This identifier is specific to the integrator and is generated by the integrator. This is the identifier that the integrator knows this refund by.

For convenience, this identifier is included with in the remittance details
result

enum (RefundResultCode)

REQUIRED: Result of this refund.
rawResult

object (RawResult)

OPTIONAL: Raw result of this refund. 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.

This value is required if the result is not SUCCESS.

RefundResultCode

The unique result codes refunds.

Enums
UNKNOWN_RESULT Do not ever set this default value!
SUCCESS Successful refund.
NO_MONEY_LEFT_ON_TRANSACTION redirect-payment-token-v1.refund failed, there is no money left on the transaction. Typically this represents bug between the integrator and Google. Google should not ask to refund an amount greater than the original capture.
ACCOUNT_CLOSED

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.
ACCOUNT_CLOSED_ACCOUNT_TAKEN_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.
ACCOUNT_CLOSED_FRAUD

ACCOUNT_ON_HOLD 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.
REFUND_EXCEEDS_MAXIMUM_BALANCE 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.
