# Refund

 A refund is performed against a previous payment, referencing its `payment.id` by sending a POST request over HTTPS to the /payments/{id} endpoint. A refund can be performed against debit (DB) or captured preauthorization (PA->CP) payment types. Where supported, the amount field can be used to process a partial or full amount.

Example:

```
curl https://test.oppwa.com/v1/payments/{Payment ID} \
 -d "entityId=8ac7a4ca6db97ef1016dbe9214e70aac" \
 -d "amount=10.00" \
 -d "currency=BRL" \
 -d "paymentType=RF" \
 -d "testMode=EXTERNAL" \ Test Evroment Only
 -H "Authorization: Bearer OGFjN2E0Y2E2ZGI5N2VmMTAxNmRiZTkwZTMxZDBhYTh8WENkRUs0NHJubQ=="
```
