See also the Transaction response object.

You can refund transactions that have a status of settled or settling. If the transaction has not yet begun settlement, use Transaction::void() instead. If you do not specify an amount to refund, the entire transaction amount will be refunded.

$result = $gateway->transaction()->refund('the_transaction_id');

If the transaction can't be found, you'll receive a Braintree_Exception_NotFound exception.

If the refund fails, then the result will be unsuccessful and will include either validation errors indicating which parameters were invalid, or a processor settlement response code indicating the type of settlement failure.

$result->success
# false

Arguments

Additional Parameters

Requirements

• Transaction status must be settled or settling.
• Refund amount can't be greater than remaining non-refunded amount of the original transaction.
• Transaction can't be refunded again after being completely refunded.
• Transactions held in escrow can only be refunded in full. Attempts to partially refund an escrow transaction will throw a validation error.

Examples

Partial refunds

If you only want to refund a portion of the transaction, specify the amount to refund:

$result = $gateway->transaction()->refund('a_transaction_id', '50.00');
$result->success
# true
$result->transaction->type
# 'credit'
$result->transaction->amount
# "50.00"

$result = $gateway->transaction()->refund('a_transaction_id', '10.00');
$result->success
# true
$result->transaction->type
# 'credit'
$result->transaction->amount
# "10.00"

We support single and multiple partial refunds on a given transaction. You can continue to refund a transaction as many times as you like, as long as the sum of the refund amounts is less than the amount of the initial transaction.

If you have already partially refunded a transaction and you perform another refund without specifying the balance, we will refund the remaining non-refunded amount of the transaction.

Settlement failures

If the processor declines the capture for the refund transaction, the transaction object will have the $processorSettlementResponseCode available. See the transaction statuses page for additional information on the Settlement Declined response.

$result->success
# false

$result->transaction->status
# "settlement_declined"

$result->transaction->processorSettlementResponseCode
# e.g. 4001

$result->transaction->processorSettlementResponseText
# e.g. "Settlement Declined"

Issuing a credit

You can use credit transactions to give a customer money. However, you should refund to an existing payment method whenever possible.

The only required parameters to create a credit transaction are the amount and the payment method token.

$result = $gateway->creditCard()->credit(
  'the_token',
  ['amount' => '100.00']
);
