# Introduction

> The TapiPay API for creating and managing charges: debts, subscriptions, and payment links.

The **TapiPay Facade API** is the simplest way to integrate charges into your product. You define **what** you want to charge (a one-time debt, a recurring subscription, or a payment link) and TapiPay handles all the internal complexity for you, starting from your token.

You don't need to know the platform's internal details (company, modalities, generationData): you work with clear business concepts and a clean contract.
