Connect Unzer to Hypamoon

The check

Three questions about the API of Unzer, answered from its own docs.

Public API docs
Yes. Read the docs
A key you create yourself
Yes. A test account comes with sandbox keys; production keys come with your Unzer contract, without a separate API request. docs.unzer.com
Versions or a changelog
Yes. Dated news and release entries, and versioned API references. docs.unzer.com
How it signs in
Your private key gets a bearer token from the token endpoint (valid a few minutes); basic auth with the private key is the legacy method.
Webhooks
Yes. It can tell your app when something changes. docs.unzer.com
Hosting
Cloud
Condition
Production keys come after you sign an Unzer contract.

Your own payments overview on Unzer, for your team and your customers.

  • Payments, charges, refunds and customers, from the Unzer API and webhooks.
  • AI that spots failed payments and drafts a reminder, with you approving what goes out.
  • A screen for your team and an email when a payment needs a look.

Ask your chat

Answers straight from your Unzer data, in Claude or another chat with the full Hypamoon connection.

  • Which payments were charged back this month?
  • Which invoices paid by bank transfer are still open?

When something happens

Unzer sends a webhook to your app, and the app asks AI what happens next.

  1. When

    A payment fails or is charged back.

    AI decides

    AI checks the order and decides whether a reminder or a call makes sense.

    Then

    The right colleague gets an email with the advice.

A screen for your team or customers

An app on your own address, with sign-in, on top of the same Unzer data.

  • For your customers

    Customers sign in and see their own payments and refunds.

Unzer stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in Unzer waits for your approval, one call at a time. How adapters work

Good to know

  • Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow.
  • Webhooks are registered through the API with a URL and the events you want. The token endpoint allows two new tokens per second, so reuse tokens.
