# Transactions

Once an authorization request is approved, the status on the authorization is updated to `pending`, and the `authorization.updated` webhook event is sent. The amount is deducted from your default available balance. A transaction is then created and the `status` of the authorization is set to `closed`.

## Refunds and Reversals

When a dispute is raised on a transaction or a reversal is initiated by the switching network, we create a new transaction it's `type` is set to `refund`, and all amounts in positive. We keep every other detail as it is in the original transaction including the authorization that leads to the refund. We also send a `transaction.refund` event with the details of the refunded transaction to your webhook.
