Request refund

1. Get payment token

Start by generating a payment token. Make a HTTP POST request to the relevant endpoint + /api/oauth/token/ using the access token you generated.

Request

curl --location --request POST 'https://uat.app.payvyne.com/api/oauth/token' 
--header 'Content-Type: application/x-www-form-urlencoded' 
--data-urlencode 'grant_type=client_credentials' 
--data-urlencode 'client_id=<payment_key>'
--data-urlencode 'client_secret=<payment_secret>’

2. Create refund request

Then, create a RR. Send an HTTP POST request to the relevant endpoint + /api/v1/refunds/init including the headers Authorization: Bearer <payment_token>. The RR body should contain an array of payments with paymentId and amount corresponding to each refund required.

Request

curl --location --request POST 'https://uat.app.payvyne.com/api/v1/refunds/init' \
--header 'Authorization: Bearer <payment_token>' \
--header 'Content-Type: application/json' \
--data-raw '{

`payments`

Parameter	Description
paymentId	16 digit alphanumeric unique payment identifier.
amount	The amount to be refunded.
idempotencyId	A unique value, between 16 and 64 characters, which the resource server uses to recognise subsequent retries of the same request.

A successful RR returns a 202 response code and an object with refunds and/or errors arrays.

If something unexpected happened during the request, the API returns an error response with the appropriate HTTP status code and a JSON response that contains detailed information about the problem.

Unsuccessful refunds may be automatically reattempted before a failed status update is provided. Our API supports idempotency for safely retrying requests without accidentally performing the same operation twice. Read more about idempotent requests here.
Requests relating to separate payments should use a unique idempotencyId if the previous request with the same idempotencyId was successful (for example, in the case of multiple or partial refunds). If you send the same paymentId and idempotencyId, the response will contain details of the original request and a new request won't be created. A webhook notification is sent containing the final refund status. If a refund status is FAILED, make the request again with a new idempotencyId to retry the refund safely.
