You can use a Fintoc standardized Mexican bank account number (CLABE) for one user’s payments or for a single payment order. This guide explains how to configure a CLABE to reject unwanted inbound transfers.

Disable a CLABE

If you disable a CLABE, Fintoc automatically rejects all inbound transfers sent to it and returns them to the sender. Disable a CLABE when you no longer want to receive inbound transfers through it.

Example use cases

Your company assigns one CLABE per user, and Jared has completed offboarding from your app. Disable Jared’s CLABE to return subsequent inbound transfers automatically.
Your company assigns one CLABE per order, and Richard bought a computer from your store. Disable the order’s CLABE after Richard pays to prevent a duplicate payment. If Richard pays twice, Fintoc automatically returns the second transfer.

Disable a CLABE with the API

account_number = client.v2.account_numbers.update(
  "acno_Kasf91034gj1AD",
  status="disabled"
)

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

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 amount limits for inbound transfers to your CLABE. If a transfer does not meet these limits, Fintoc rejects it. Rejected transfers do not appear on your account statements and do not incur fees. Use the following options to set amount limits:

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

account_number = client.v2.account_numbers.create(
  options={
    "min_amount": 300,
    "max_amount": 400
  }
)

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

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
     }
   }
