# Legacy Token Checkout

{% hint style="danger" %}
This solution is deprecated, as we are migrating to a serverless solution in our new Token Checkout mechanism - [New Token Checkout](https://docs.paytweed.com/getting-started/token-checkout-or-payments/token-checkout)

in V2 you don't need to have a backend for your application - all the catalog management is performed through our [Management Dashboard](https://docs.paytweed.com/developer-tools/management-dashboard) / [API](https://docs.paytweed.com/developer-tools/api/api-v2)

{% hint style="info" %}
**Before starting the integration**\
The token checkout process requires backend implementation to handle sensitive parameters like price and others. This ensures flexibility by allowing dynamic parameters for each transaction, even within the same contract. To facilitate this, we built a backend SDK for Node.JS servers, making the integration easy, secure, and convenient.

To begin use backend SDK please contact us to obtain API keys.
