# Test with sample tokens

This page describes how to use sample tokens to test your integration.

## Generate sample tokens

In order to test token decryption on your server for direct integrations, you can generate
sample tokens if you set the environment to `TEST` when you construct a
`PaymentsClient` instance.

When the `PaymentsClient` instance is constructed with the environment set to
`TEST`, the calls to `loadPaymentData` work as usual, and they request
that the user selects one of their real cards. However, it never actually returns real information
from the card that was selected. Instead, the token that results always has a constant
payload.

> [!CAUTION]
> **Important:** Your real card details are never used when the environment is set to `TEST`, but you must [add at least one chargeable card to your Google account](https://support.google.com/pay/answer/7625139) before you proceed. In addition, to generate sample tokens for tokenized cards, you need to [install and add at least one supported payment method to the
> Google Wallet app](https://support.google.com/pay/answer/6289372).

> [!NOTE]
> **Note:** Google doesn't provide test cards. Reach out to your acquiring bank if you need chargeable test cards.

## Verify signature

The tokens produced in the environment `TEST` are encrypted with your test public key
that was previously sent to Google.

The tokens are signed with
[Google's test keys](https://payments.developers.google.com/paymentmethodtoken/test/keys.json). If you use Tink, ensure that
`.fetchSenderVerifyingKeysWith(GooglePaymentsPublicKeysManager.INSTANCE_TEST)` is set
when you build a `PaymentMethodTokenRecipient` object.

## Decrypted payload

> [!CAUTION]
> **Important:** The payload samples provided here are illustrative only.

Once the sample token is decrypted, you receive the cleartext payload. The payload structure
depends on whether the card that was selected is tokenized, which means it's been added to Google
Pay, or not. In addition, the payload for tokenized cards is different, which depends upon the
card network. The payload for non-tokenized cards is always the same, regardless of card network.

The following three fields may differ in your decrypted payload compared to the samples on this
page:

- `messageExpiration`: A timestamp set one week from the current time.
- `messageId`: This is randomly generated for each payload.
- `expirationYear`: This is set five years from the current year.

The structure of the decrypted payload varies between two protocol versions, ECv1 and ECv2. If you
implement a new integration, the version is ECv2. If you're uncertain about the protocol version,
confirm it with your Google point of contact.
