# Customization

> What can be customized on the Ramp Checkout today, and what is planned.

The Ramp Checkout is Onstacks branded. Today the only customization is the starting side of the flow through the `tab` parameter.

| Option | Available |
| - | - |
| Start on buy or sell | Yes, `?tab=onramp` or `?tab=offramp` |
| Prefill amount, token, currency | Planned |
| Prefill destination wallet address | Planned |
| Return URL after completion | Planned |
| Your logo and colours | Planned |

For your own name, colour and fixed amounts inside your website, use the [Widget](/ramps/widget/quickstart).

If you need any of the planned options for a launch, tell support which ones and we will prioritise them. For full control of the experience use the [White-Label API](/ramps/api/overview).
