# Test your integration

> Simulate transfers on Fintoc's legacy v2023-11-15 Transfers API sandbox to validate your integration before switching to live API keys and real funds.

To confirm that your integration works correctly, simulate transfers without moving any money using special values in `test` mode.

Use test API keys for all API calls in `test` mode.

# Simulate an inbound transfer

Fintoc lets you simulate an inbound transfer through the API or dashboard. You can simulate an inbound transfer only for account numbers created in `test` mode. To review how to create an account number, see [this example](/v2023-11-15/guides/transfers/inbound-transfers#step-2-create-an-account-number-spei-clabe).

Use the following example to simulate an inbound transfer of \$1,020.00 MXN:

```bash Bash theme={null}
curl --request POST \
	--url 'https://api.fintoc.com/v2/simulate/receive_transfer' \
  --header 'Authorization: sk_test_9c8d8CeyBTx1VcJzuDgpm4H' \
  -d account_number_id=<acno_id> \
  -d amount=102000 \
  -d currency='MXN'
```

## Simulate with an SDK

Use the Python or Node SDK to simulate an inbound transfer:

```python theme={null}
transfer = client.v2.simulate.receive_transfer(
    amount=9912400,
    currency="MXN",
    account_number_id="acno_2vF18OHZdXXxPJTLJ5qghpo1pdU",
)
```

```javascript Node theme={null}
const simTransfer = await fintoc.v2.simulate.receiveTransfer({
    account_number_id: 'acno_2wguZyhW0ilO9AUGSWQQ7HvuXpj',
    amount: 58145,
    currency: 'MXN'
});
```

<Info>
  **Simulate endpoint**

  Endpoints under `/simulate/*` simulate production behavior and are unavailable in `live` mode.

## Test returning an inbound transfer

Use the `amount` of the simulated inbound transfer to test different return outcomes in `test` mode:

| Return Outcome                 | Inbound transfer `amount` |
| :----------------------------- | :------------------------ |
| Transfer returned successfully | Any amount                |
| Failed return                  | 99.99 MXN                 |

# Test outbound transfers

Fintoc provides special test values for Mexico and Chile. When you create a test outbound transfer, you receive the same webhooks as in `live` mode.

## Mexico 🇲🇽

Use one of the following standardized Mexican bank account numbers (CLABEs) to simulate a successful, failed, or returned outbound transfer:

| Description                                                                                                   | Counterparty                                                                                                                                         |
| :------------------------------------------------------------------------------------------------------------ | :--------------------------------------------------------------------------------------------------------------------------------------------------- |
| A regular `Transfer` succeeds if you have enough funds. Otherwise, you receive an `insufficient funds` error. | Account number: Any account number at a non-Fintoc institution.<br />Examples of valid CLABEs:<br /><br />012969100000000110<br />646969100000000214 |
| A transfer fails because of external errors.                                                                  | Account number: 012969100000000013                                                                                                                   |
| The recipient institution returns the transfer.                                                               | Account number: 012969100000000026                                                                                                                   |

## Chile 🇨🇱

Use one of the following counterparties to simulate transfers in Chile:

| Description                                                                                                   | Counterparty                                                                                                                                                                       |
| :------------------------------------------------------------------------------------------------------------ | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| A regular `Transfer` succeeds if you have enough funds. Otherwise, you receive an `insufficient funds` error. | `holder_id`: Any valid Chilean tax ID (RUT)<br />`holder_name`: Any name<br />`account_number`: Any account number<br />`type`: Any type<br />`institution_id`: Any institution ID |
| A `Transfer` fails because of insufficient funds.                                                             | `holder_id`: 41579263-8<br />`holder_name`: Any name<br />`account_number`: Any account number<br />`type`: Any type<br />`institution_id`: Any institution ID                     |
| A reversal returns the `Transfer`.                                                                            | `holder_id`: 40427672-7<br />`holder_name`: Any name<br />`account_number`: Any account number<br />`type`: Any type<br />`institution_id`: Any institution ID                     |
