[**Required Number of Transaction Confirmations**](#user-content-fn-1)[^1] - a confirmed transaction means it has been included in a block and, therefore, in the blockchain. It has been verified and recorded, the payment has been processed, and it cannot be changed or canceled. To be considered legitimate, the operation must receive a certain number of confirmations. Each new confirmation exponentially reduces the risk of the transaction being reversed.

## Continuing the Setup

Next, configure the merchant by following the [general setup instructions](https://premium.gitbook.io/main/en/en/basic-settings/merchants-and-auto-payments/merchants/general-merchant-settings).

[^1]: 6 confirmations is the standard for most transactions considered safe.
