How it works
Apply Interest Rates
As described in your agreement, each installment number has its own interest rate. You can use this agreement values to calculate the final amount. Before sending the payment request to EBANX, you need to calculate the final amount of the payment based on the installment number chosen by the customer.
Here's an example of the calculation:
amount = (((interest_rate + 100) / 100) * (orderTotal));
The EBANX API expects the final value, with interest rates, so, make sure you calculate it before sending your request to Direct API.
If you are working with a e-commerce module, such as Shopify, you may notice that some of them have the option for you to put the interest rate manually on the configurations of the module. You have to keep that number 0 (zero) since you will apply the interest rate on each instalment by code.
Send the payment request with installments
