7. Additionally, you can configure the following settings:

   * **Transaction Type** — can be set to Authorize & Capture or Authorize Only. Authorize Only allows you to capture the funds manually. See [Manually Capturing Transactions (Authorize Only)](https://support.bigcommerce.com/s/article/Manually-Capturing-Transactions-Authorize-Only) to learn more.

   * **Test Mode** — set this to *Yes* to test checkout flow. Make sure this is set to *No* when your store goes live.
