# Configure client side

> Client-side setup for integrating Tesouro into your application.

Tesouro provides three integration paths: Drop-in components, a React SDK, and direct API calls. Pick based on how much UI control you need.

## Drop-in

Drop-in is Tesouro's library of framework-agnostic Web Components you insert directly into your HTML.

To get started, follow [Drop-in quick start](/finops/guides/embedded-components).

## React SDK

Tesouro's React SDK is a library of ready-to-use components wired to the Tesouro API, for both client-side and server-side React apps. You control styling and branding; the SDK handles data fetching and state.

To get started, follow [React SDK quick start](/finops/guides/embedded-components).

## API-only

Call Tesouro's API endpoints directly from your backend. You own the entire integration: request shaping, error handling, and UI rendering.

To get started, follow any product guide, such as [Accounts Payable](/finops/guides/accounts-payable/index) or [Accounts Receivable](/finops/guides/accounts-receivable/index).
