Each processed order can be refunded using refunds API described here: Refunds API
Refund is basically payment resource related to specific order where sender and destination accounts are switched comparing to original payment created to collect money from the merchant’s customer (when merchant’s customer paid to merchant).
They can, similarly to payments, be processed by one of two flows:
Redirect flow
Embedded flow
A single order can have multiple refunds.
The maximum amount of the refund is restricted by the value specified in the field “refundLimitPercentage“ provided in the request body when creating the order. By default (if not specified) it is 100% (meaning the same amount as the amount of the order). If set to 0, the limit is not applied.
Refund initialization
To initialize a refund, you send the information about refunded amount and payment sender/recipient information. Everifin responds with an refund ID and redirect link pointing to Everifin Paygate page.
Refund initialization requests and responses are very similar to order initialization https://everifin.atlassian.net/wiki/spaces/EPAD/pages/2562228372/Payment+Orders#Order-initialization.

Checking of duplicated refunds
InstructionId of a refund should be unique. If instructionId is supplied by the client, Everifin paygate checks, whether an identical refund already exists. If an identical refund already exists, the request is denied to prevent accidentally created refunds.
Refund is considered to be duplicated, if all of these values are equal for existing refund:
instructionId
amount
reason
reference
variableSymbol
specificSymbol
constantSymbol
recipientIban
paymentMessage
Also, a matching refund must not be in states FAILED, WITHDRAWN or EXPIRED.
Error codes
Create refund endpoint can return error codes described in the following table:
code | description |
|---|---|
REFUND_LIMIT_EXCEEDED | Refund limit for an order was exceeded. Refund limit is compared against sum of all order’s refunds, which are not FAILED, WITHDRAWN or EXIPRED plus the amount of requested refund. If the requested sum of refunds is higher than the limit specified and calculated in the order (refundLimitPercentage), this error is thrown. To change the refund limit for an order, call Update Order endpoint and set the refundLimitPercentage to a higher value (or 0, if the limit should not be checked |
REFUND_CANNOT_BE_CREATED | Refund can not be created for an order at this moment. Possible reason is that no payment was initialized for the order, yet. Refunds can be only initialized for orders, whose payment’s processing was started. |
REFUND_DUPLICATED | The same refund was already created. To prevent duplicated refunds, it is not possible to create two identical refunds for a single order. To create a refund with the same payment data (amount, reference etc.), change at least instructionId (which should be unique) or reason. |
NOT_AUTHORIZED | Client is not authorized to create refund. Refunds scope might be missing. |
