How to identify an invoice debit?
In the "NET_DEBIT_AMOUNT" column, you will find the amount that was discounted and the "EXTERNAL_REFERENCE" will show a description that will begin with the word “MELIPAYMENTS”.
In the "Activity" section, you can use the transaction ID to find more information about this debit. You will also find more details in the "Billing" section of Mercado Libre.
