## Technical configuration

### Payments API calling preparation

If you need to call Payments API, you need to follow these steps to complete API key configuration.

1. Refer to the [Developer guide](/payments/en/developer-tools/get-started-with-api) to generate an API key and API secret pair, and register the API key in Cobo Portal. Please note the following configurations:
   * **User role**: Select **Payment admin**
   * **Wallet scope**: Select **Any wallet type**
   * **Key type**: Select **Temporary**

2. If you choose to use an SDK instead of manually writing API requests, you need to install the SDK for the corresponding programming language:
   * [Python SDK quickstart](/payments/en/developer-tools/quickstart-python)
   * [Java SDK quickstart](/payments/en/developer-tools/quickstart-java)
   * [Go SDK quickstart](/payments/en/developer-tools/quickstart-go)
   * [JavaScript SDK quickstart](/payments/en/developer-tools/quickstart-javascript)

### Subscribe to webhook events

If you need to receive real-time notifications of payment-related events, you can set up and register a webhook endpoint to receive webhook events. Specific steps are as follows:

* Refer to the [Developer guide](/payments/en/developer-tools/set-up-endpoint) to set up a webhook endpoint.
* [Register the webhook endpoint](https://manuals.cobo.com/en/portal/developer-console/webhooks-create) in Cobo Portal and subscribe to [payment-related webhook events](/payments/en/guides/status-and-events).

## Business configuration

### Top up Fee Station

During your daily business operations, you need to manage various fees incurred on Cobo through [Fee Station](https://manuals.cobo.com/en/portal/fee-station/introduction). Before you start integration, please ensure that you have sufficient funds in your Fee Station to pay for fees generated during payouts, refunds, and other processes:

* You can use USDT or USDC as the fee token
* The recommended initial top-up amount is equivalent to approximately 50 USD in cryptocurrency. You can adjust the top-up amount based on actual business needs.

For specific top-up operation steps, refer to the [Top up Fee Station](https://manuals.cobo.com/en/portal/fee-station/deposit) document.

## Next steps

Refer to the [Feature list](/payments/en/guides/features#pay-ins) to select the pay-in mode suitable for you and refer to the documentation to complete payment collection feature integration.
