# Finup API

> Use the Finup API to manage accounts, cards, users, and transaction data.

The Finup API lets approved clients integrate with Finup accounts, cards, and transaction data.

This documentation is intentionally limited to client-facing endpoints. Internal admin, frontend-only, support, marketing, script, and webhook-processing endpoints are not included here.
