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.

​
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.

​
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 or Accounts Receivable.
