## API reference

You do not need to send additional fields for Trustly. To see optional fields that you can send for all payment methods, choose the endpoint you integrated:

* [/sessions](https://docs.adyen.com/api-explorer/Checkout/latest/post/sessions): This is the default with [Drop-in v5.0.0](/online-payments/build-your-integration/sessions-flow?platform=iOS\&integration=Drop-in) or later.
* [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments): If you implemented an [additional use case](/online-payments/build-your-integration).

## Drop-in configuration

## Test and go live

Trustly provides a [test environment](https://docs.trustly.com/get-started/adyen). For **Login ID/Personal number** values, you can enter any digits, following the format `YYMMDD-XXXX` (for example: **111111-1111**).

You can check the status of Trustly test payments in your [Customer Area](https://ca-test.adyen.com/) > **Transactions** > **Payments**.
