Introduction

ProAbono is a subscription-billing platform and API Live is designed to craft your end-users experience in a few calls.

The ProAbono API Live lets you manage subscriptions programmatically — create customers, start or update subscriptions, check feature access, and calculate billing costs before committing to a change.

Before getting started, you need a ProAbono account. Sign up here to create one.

Caution

Never call this API from a browser. Your API key would be exposed in network requests, browser DevTools, and JavaScript bundles — readable by any user.

Route calls through your own backend instead:

Browser → Your backend → ProAbono API Live

Your backend holds the API key; the browser never sees it.
