# Add logic to CLABEs

> Reject all transfers directed to any specific CLABE.

There are different ways to use your Fintoc CLABE. You can assign a CLABE to a specific user's payments or create a single-use CLABE for specific payment orders. This guide shows how to update your CLABE to make payin handling easier.

# Disable a CLABE

If you disable a CLABE, **all payins directed to it will be automatically rejected** and returned to the sender. This way, if a CLABE is no longer intended to receive payments, by disabling it you no longer need to worry about handling stray inbound payments.

If you disable a CLABE, **all payins directed to it will be automatically rejected** and returned to the sender. If a CLABE is no longer intended to receive payments, disabling it prevents you from handling stray inbound payments.

## Example use cases

* Your company assigns **one CLABE per user** and Jared has completed offboarding from your app. Disable Jared's CLABE so payments made for Jared's user are automatically returned and don't waste your operational resources.
* Your company assigns **one CLABE per order** and Richard bought a computer at your store. Disable Richard's computer order CLABE once he has paid to avoid receiving a double payment. If Richard misses the payment confirmation notice and pays twice, the money will be returned automatically and won't waste your operational resources.

## Disabling a CLABE with our API

```python theme={null}
account_number = client.v2.account_numbers.update(
  "acno_Kasf91034gj1AD",
  status="disabled"
)
```

```node theme={null}
const accountNumber = await fintoc.v2.accountNumbers.update(
	"acno_Kasf91034gj1AD",
  status: 'disabled'
);
```

```curl theme={null}
curl --request PATCH \
     --url https://api.fintoc.com/v2/account_numbers/acno_jKaHD105H \
     --header 'Authorization: sk_test_jKaHdEa3mfmP0D105H' \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '
{
  "status": "disabled"
}
'
```

# Set inbound transfer amount limits

You can set boundaries to restrict which **inbound transfers** your CLABE accepts. If a transfer does not meet these criteria, Fintoc rejects it. Rejected transfers do not appear on your account statements and do not incur fees.

| Feature        | Description                                                                                                               |
| :------------- | :------------------------------------------------------------------------------------------------------------------------ |
| Minimum amount | Set `min_amount` to reject any transfer with an amount lower than this value.                                             |
| Maximum amount | Set `max_amount` to reject any transfer with an amount higher than this value.                                            |
| Exact amount   | Set both `min_amount` and `max_amount` to the same value to reject any transfer that does not match that specific amount. |

## Setting limits via API

```python theme={null}
account_number = client.v2.account_numbers.create(
  options={
    min_amount=300,
    max_amount=400
  }
)
```

```node theme={null}
const accountNumber = await fintoc.v2.accountNumbers.create(
  options: {
  	max_amount: 300,
  	min_amount: 400
  }
);
```

```curl theme={null}
curl --request POST \
     --url https://api.fintoc.com/v2/account_numbers \
     --header 'Authorization: sk_test_jKaHdEa3mfmP0D105H' \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '
     {
     "options": {
     	max_amount: 400,
     	min_amount: 300
     }
   }
'
