# Overview

> Base URL, versioning, and where to start with the Whop API.

The Whop API lets you accept payments, pay out users, manage products, and move money on Whop programmatically. The base URL is `https://api.whop.com/api/v1`, and the API is versioned by date. Send an `Api-Version-Date` header to pin a stable contract so changes never break your integration. See [Versioning](/developer/api/versioning) for details.

<Note>
  You authenticate with a Bearer API key. Create one in the
  [Quickstart](/api-reference/beta/quickstart) and keep it on your server, never
  in browser or mobile code.
