# Refund a split funded transaction

> Learn how to refund a transaction that was sent with split instructions

<AudienceInfo audiences={['developers']} />

How you refund a split funded transaction depends on whether you want to do a full refund or a partial refund.

## Full refunds

Full refunds of a split transaction work the same as refunds for a transaction without splits. Payabli returns the total of the transaction, less any pass-through fees, to the payor, reversing the original transaction's split instructions. For example, a \$103 transaction had a \$100 total, plus a \$3 pass-through fee. Payabli returns \$100 to the payor, removing the funds from the same accounts the funds were originally split into.

<Note>
  To run a full refund, see [the refund](/guides/pay-in-developer-transactions-cancel#refund-a-transaction) guide for help.

  A request to this endpoint refunds the transaction based on the original transaction's split instructions.
</Note>

## Partial refunds

Payabli accepts partial refunds when the original transaction was split *only if* the refund request includes split instructions. You must specify how much to return to the customer, and from whom.

### Partial refund considerations

* You can only make refunds from the accounts and entrypoints used in the original request.
* You don't have to include every account on the original transaction in a partial refund request.
* An account can't refund more than it received in the original transaction. For example, if Account A received \$35 in the original transaction, you will get an error if you try to refund more than \$35 from Account A.
* The split amounts are validated for partial refunds. They can't total more than the original transaction, or the refund request fails.

  <Accordion title="Example: Partial refund from all accounts on a split">
    For example, a \$103 transaction had a \$100 total plus a \$3  pass-through fee. The \$100 total was split three ways:

    * Account A received \$50
    * Account B received \$30
    * Account C received \$20

    A partial refund request comes with split instructions that request \$20 from Account A , \$10 from Account B , and \$5 from Account C. Payabli takes the designated amount back from those recipients and returns a total of \$35 to the Payor.

    Accounts A, B, and C retain the balance from the original transaction:

    * Account A keeps \$50 - \$20 = \$30
    * Account B keeps \$30 - \$10 = \$20
    * Account C keeps \$20 - \$5 = \$15.

  <Accordion title="Example: Partial refund from some of the accounts on a split">
    For example, a \$103 transaction had a \$100 total plus a \$3  pass-through fee. The \$100 total was split three ways:

    * Account A received \$50
    * Account B received \$30
    * Account C received \$20

    A partial refund request comes with split instructions that request \$20 from Account A and \$10 from Account B. Payabli takes the designated amount back from those recipients and returns a total of \$30 to the Payor.

    Accounts A, B, and C retain the balance from the original transaction:

    * Account A keeps \$50 - \$20 = \$30
    * Account B keeps \$30 - \$10 = \$20
    * Account C keeps \$20 - \$0 = \$20.

## Split refund examples

To refund a split transaction, send a POST request to api/MoneyIn/refund/\{transId}. This endpoint is used to refund a transaction that was sent with split instructions. See the [API reference](/developers/api-reference/moneyin/refund-a-settled-transaction-with-instructions) for full information.

The Refund endpoint has a required path parameter, `transId`, which is the `referenceId` for the transaction.

<ParamField path="transId" type="string" required>
  The referenceId identifying the transaction (PaymentId). You can find this in the success response for the payment you want to refund.
</ParamField>

There is a required request body, which is a JSON object.

This example refunds the transaction with a `referenceId` of `10-3ffa27df-b171-44e0-b251-e95fbfc7a723` for the total amount of the \$100 transaction.

<EndpointRequestSnippet endpoint="POST /MoneyIn/refund/{transId}" example="FullSplitRefund" />

This example refunds a partial amount of \$70 (out of \$100) of the transaction with a `referenceId` of `10-3ffa27df-b171-44e0-b251-e95fbfc7a723`.

<EndpointRequestSnippet endpoint="POST /MoneyIn/refund/{transId}" example="PartialSplitRefund" />

A successful refund returns a 200 status with a JSON body.

<EndpointResponseSnippet endpoint="POST /MoneyIn/refund/{transId}" example="PartialSplitRefund" />
