# Transaction

Transactions are created for every order that results in an exchange of money.

There are five types of transactions:

* **Authorization**: An amount reserved against the cardholder's funding source. Money does not change hands until the authorization is captured.
* **Capture**: A transfer of the money that was reserved during the authorization stage.
* **Void**: A cancellation of a pending authorization or capture.
* **Refund**: A partial or full return of captured funds to the cardholder. A refund can happen only after a capture is processed.

Refund transactions must be created by using the [Refund resource](https://api-doc.shopbase.com/#tag/Refund).

### Note

An order can have no more than 100 transactions associated with it.
