# Changelog

> Changes to the Hoppier API, webhooks and AI-assistant connectors.

We announce changes here before they affect documented behaviour. New fields and error codes can appear without notice, so ignore anything you don't recognise.

**October 2026**

Docs launched

The Hoppier developer docs are live. They cover:

* the REST API's `GET /validate`, `GET /programs`, `GET /programs/{program}` and `POST /participants`,
* the `card.claimed` webhook,
* the Zapier app,
* Hoppier's two MCP servers for Claude, ChatGPT and other AI assistants.

What's next is on [Coming soon](/guides/coming-soon.md).
