I am trying to refund a payment made through the terminal api, but I get the following error

code: 'REFUND_AMOUNT_INVALID',
      detail: 'The requested refund amount exceeds the amount available to refund.',
      category: 'REFUND_ERROR'

This is the payment

}

this is the refund request object

{
  "idempotency_key": "1ad63ed6-537c-4079-bc88-8ad614225165",
  "amount_money": {
    "amount": 20,
    "currency": "GBP"
  },
  "payment_id": "bP1GqGdh2OZtBXO8SBkeR1isuaB"
}

The amount is clearly less than the payment, so why am I getting the error?

Looks like payment is already refunded which is why your getting the error. :slightly_smiling_face:
