When showing the price financed in installments, you must indicate the actual price, the total financed price, the number and amount of each installment, the annual effective interest rate applied and the total financial cost. 2. In case you sell products and/or services based on the modality financed in installments, you are not allowed to include the phrase “without interest rate” (or any other similar) when the cost of financing is transferred to the retail price. 3. The information about the total financial cost (CFT) of the transaction must be placed near the other variables reported in the previous point, highlighted in bold using the same font and size at least FIVE (5) times bigger – while preserving all proportions of stroke thickness, height and width – in relation to that used to report the annual effective interest rate (TEA) applied. Multiplying the width of the sides x 2.25 is sufficient. Example: ![cft-tea](/images/resources/tea-cft.png) ### Get the TEA and CFT The TEA and the CFT can be obtained through our API using the `installments` feature. To make the request, you need to submit the `payment_method_id` and the `bin` (first 6 digits of the card). Example: ``` curl -X GET \ -H "accept: application/json" \ -H 'Authorization: Bearer TEST-5252485006568871-060216-a48700bfc7c55fd627e1a107f7ece57e__LA_LB__-110261734' \ "https://api.mercadopago.com/v1/payment_methods/installments?[payment_method_id=:id]&[bin=:bin]&[amount=:amount]&[issuer.id=:issuer_id]" ``` The result will be a list of installments that will contain this information within the `labels` attribute: ```json { ..., "payer_costs": [ { "installments": 1, "installment_rate": 0, "discount_rate": 0, "labels": [ "CFT_0,0%|TEA_0,0%" ], "min_allowed_amount": 0, "max_allowed_amount": 250000, "recommended_message": "1 cuota de $ 1.000,00 ($ 1.000,00)", "installment_amount": 1000, "total_amount": 1000 }, { "installments": 3, "installment_rate": 0, "discount_rate": 0, "labels": [ "CFT_70,21%|TEA_89,43%" ], "min_allowed_amount": 2, "max_allowed_amount": 250000, "recommended_message": "3 cuotas de $ 369,90 ($ 1.109,70)", "installment_amount": 369.90, "total_amount": 1109.70 } ] } ``` It is worth noting that in case of 1 installment or installments related to [promotions](https://www.mercadopago.com.ar/promociones) with no interest, they will have the values of TEA and CFT equal to 0. Although the value is 0, in scenarios where the customer chooses more than one installment, you must show it in the purchase form anyway. ### Code sample Find below an example to assist you with this implementation: ```html ``` Your HTML should already contain the following script: ``` ``` We will use the Mercado Pago library to check the `installments` feature. ```javascript ```
