Overview

Boleto.Cloud is a Brazilian payment API that lets you generate boletos — the popular Brazilian bank slip payment method used widely for bills and online purchases. If you are building an e-commerce or billing application for the Brazilian market, this API handles the complex boleto generation rules for you. It requires an API key and is designed for developers serving Brazilian customers.

💡

Beginner Tip

Boletos are a Brazil-specific payment method, so this API is only relevant if you are targeting Brazilian customers. Make sure your boleto expiration date is set at least 1-3 days in the future since same-day boletos are often rejected by banks.
