# OneTimeBuyLineItem

The line item that indicates a one-time charge transaction.

```
object OneTimeBuyLineItem
```

## Discussion

Use a `OneTimeBuyLineItem` to report a one-time charge transaction, or a correction to a one-time charge transaction that you previously submitted.

Each line-item object represents one transaction. Other types of line-item objects include:

- [`SubscriptionBuyLineItem`](/documentation/ExternalPurchaseServerAPI/SubscriptionBuyLineItem), for reporting subscription-related transactions
- [`RefundLineItem`](/documentation/ExternalPurchaseServerAPI/RefundLineItem), for reporting refunds

Include the line-item objects in the `lineItems` array of an [`ExternalPurchaseReport`](/documentation/ExternalPurchaseServerAPI/ExternalPurchaseReport) object. To send the report, include the [`ExternalPurchaseReport`](/documentation/ExternalPurchaseServerAPI/ExternalPurchaseReport) object in a request to the [`Send External Purchase Report`](/documentation/ExternalPurchaseServerAPI/Send-External-Purchase-Report) endpoint.

For more information, see [Reporting tokens with transactions](/documentation/ExternalPurchaseServerAPI/reportwithtransactions) and [Reporting corrections](/documentation/ExternalPurchaseServerAPI/reportcorrections).
