title: How to Test Using Sandbox Credentials

subtitle: 'Staging credentials, test cards, and KYC flows for integration testing'
----------------------------------------------------------------------------------

## KYC

The KYC (Know Your Customer) experience on the staging environment closely mirrors the experience on the production environment. The primary difference between the two environments is that all checks performed on the staging environment are dummy checks, and the KYC result on staging is always approved.

### Creating Test Account in Staging: (Europe Account)

You can use the below credentials to create a staging account for **France** KYC Level 1 and Level 2 verified users.

* **Level 1**: Lite KYC — Only Personal and Address details are required.
* **Level 2**: Standard KYC — Personal, Address, and ID Proof (Document and Selfie) are required.

## Simulating Failed & Refunded Orders

To simulate failed and refunded orders in the staging environment, simply use special email aliases. This allows you to test how your system responds to unsuccessful transactions across all Transak products.

### How to Simulate

<Steps>
  <Step title="Use special email aliases when placing test orders">
    * Add `+review` to your email address to simulate a refunded order.
    * Add `+failed` to simulate a failed order.

    | Base Email    | Refund Email         | Failed Email         |
    | :------------ | :------------------- | :------------------- |
    | `xyz@abc.com` | `xyz+review@abc.com` | `xyz+failed@abc.com` |

    <Frame>
      <div>
        Most email providers support plus addressing, so emails sent to aliased addresses like `yourname+refund@example.com` will still be delivered to your main inbox.
      </div>
    </Frame>
  </Step>

  <Step title="Place a test order in the staging environment">
    Use any available payment method.
  </Step>

  <Step title="Check the simulated result">
    * Orders made with a `+review` email will automatically be marked as **REFUNDED**
    * Orders made with a `+failed` email will automatically be marked as **FAILED**
  </Step>
</Steps>

## Blockchain Testnets (Onramp)

`ERC-20` token transfers across the following five networks will utilize the `ERC-20` `Transak Test Token (TRNSK)`.

* **ERC-20 example (staging):** Buying **100 USDC** on **Polygon** delivers **100 TRNSK** to your wallet; the transaction hash shows a transfer of **100 Transak Test Token**.
* **Native tokens:** Buying **1 ETH** on **Ethereum** or **100 MATIC** on **Polygon** still completes successfully, but **no tokens** are sent to your wallet.
* **Off-ramp:** Buy **TRNSK** via on-ramp, then send **TRNSK** to us to test off-ramping.

## Testing Off ramp orders

For off-ramp, place orders only for native tokens supported and transfer the official testnet token on that network for order to be reconciled automatically.
