# Create refund

Create Partial/Full Refund for a specific payment. If the amount field is filled, it will create a partial refund, if not, it will create a full refund.

**POST** `/v1/payments/{id}/refunds`

## Request parameters

### Header

- `X-Idempotency-Key` (string, required)
  This feature allows you to safely retry requests without the risk of accidentally performing the same action more than once. This is useful for avoiding errors, such as creating two identical refunds, for example. To ensure that each request is unique, it's important to use an exclusive value in the header of your request. We suggest using a UUID V4 or random strings.

### Path

- `id` (string, required)
  Payment identifier.

- `amount` (number, optional)
  Refund amount. If this property (amount) is removed from body, it will create a full refund.

  Contains payment metadata that is sent to us in the payment post.

- `source` (array, optional)
  Contains the data to identify who originated the refund (contains ID, name and type)

  - `source[].name` (string, optional)
  The name of the user who submitted the refund request.

  - `source[].id` (string, optional)
  The ID of the user who submitted the refund request (collector, operator, owner of the marketplace)

  - `source[].type` (string, optional)
  Source type. The possible values are Admin, Collector, BPP, and Marketplace.

Possible enum values:

  - `rejected`
  Payment was rejected. The user may retry payment.

  - `authorized`
  The payment has been authorized but not captured yet.

- `reason` (string, optional)

- `label` (array, optional)

- `partition_details` (array, optional)
  Indicates the amount returned for each of the partitions with which the payment was generated. Currently, payments with several money partitions are created only for one product from Brazil (Valeras), so it does not apply to all. Valeras allows offering benefits to employees, and is currently turned on in Brazil only for some employers.
