# Connect MONEI to Hypamoon

Yes. MONEI has a public, versioned API and you create the key yourself, so your chat can write the adapter.

Open

## The check

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

**Public API docs**\
**Yes.** [Read the docs](https://docs.monei.com/apis/rest)

**A key you create yourself**\
**Yes.** Your API key is in the MONEI Dashboard under Settings > API Access, with separate keys for test and live. [docs.monei.com](https://docs.monei.com/guides/verify-signature)

**Versions or a changelog**\
**Yes.** Public changelog. [docs.monei.com](https://docs.monei.com/changelog)

**How it signs in**\
The API key from Settings > API Access in the Authorization header.

**Webhooks**\
**Yes.** It can tell your app when something changes. [docs.monei.com](https://docs.monei.com/guides/webhooks)

**Hosting**\
Cloud

**Condition**\
Live mode needs an activated MONEI account.

## Your own payments and subscriptions overview on MONEI.

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

### Ask your chat

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

-   Which subscription payments failed this month?
-   How much did we take with Bizum last week?

### When something happens

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

1.  When

    A subscription payment fails.

    AI decides

    AI looks at the customer's history and drafts a short message.

    Then

    You approve it and the customer gets an email with a link to update the payment method.

### A screen for your team or customers

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

-   For your customers

    Customers sign in and see their subscription and past payments.

MONEI 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 MONEI waits for your approval, one call at a time. [How adapters work](https://hypamoon.com/docs/adapters)

### 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 set in Dashboard > Settings > Webhooks and signed with your API key. Test and live use different keys.

## Try it in your chat

Fill in what to read and write, and send it.

The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.

Say this in your chat

> Check if \[software\] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
