# Testing

> Test cards, bank transfer and virtual account scenarios for the sandbox environment

<Warning>
  To use the sandbox environment, you must generate a token using your **test credentials** (`clientId` and `clientSecret` from the dashboard) and the **sandbox base URL** (`https://sandbox.nomba.com`). Using the wrong URL or credentials will cause authentication failures. See the [Environment](/docs/api-basics/environment) page for details.
</Warning>

Endpoint paths are the same as production — the sandbox is selected by the base URL and your test credentials, so you can point an existing integration at `https://sandbox.nomba.com` without changing your routes.

## Before you start

1. **Generate a sandbox token** — `POST https://sandbox.nomba.com/v1/auth/token/issue` with your test `clientId` and `clientSecret`
2. **Set a test webhook URL** — on the dashboard under **Developer** → **Webhook Setup**, and subscribe to the events you care about. Several sandbox scenarios report their outcome only by webhook. See [Webhooks](/docs/api-basics/webhook).
