# Delete payments

`DELETE https://datafa.st/api/v1/payments`

Delete payment and free-trial records by transaction, visitor, or time range.

## Request

### Authentication

- `df_` website API key for one website.

### Query parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `transaction_id / tx_id` | string | No | Unique transaction ID from your payment provider. Used for idempotency and deletion. Delete one payment or free trial by transaction ID. Highest priority. |
| `datafast_visitor_id` | string | No | DataFast visitor UUID from the browser cookie or client SDK. Used to attach server-side events to a visitor journey. Delete all payments/free trials for one visitor. |
| `startAt / endAt` | string | Required for bulk delete | Start of the reporting window. Use it with `endAt` to query a specific date range instead of the endpoint default. Required when deleting without transaction or visitor. |
