# Connect PayU to Hypamoon

Yes, with one catch. PayU has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today.

Open

## The check

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

**Public API docs**\
**Yes.** [Read the docs](https://developers.payu.com/europe/api/)

**A key you create yourself**\
**Yes.** The client\_id and client\_secret are in your merchant panel, in the settings of the point of sale (POS). [developers.payu.com](https://developers.payu.com/europe/api/)

**Versions or a changelog**\
**Yes.** Dated changelog. [developers.payu.com](https://developers.payu.com/europe/docs/changelog/)

**How it signs in**\
The POS client\_id and client\_secret from the merchant panel, exchanged for an OAuth bearer token.

**Webhooks**\
**Yes.** It can tell your app when something changes. [developers.payu.com](https://developers.payu.com/europe/api/)

**Hosting**\
Cloud

**Condition**\
You need a verified PayU merchant account; sandbox and production are separate accounts.

## Your own order and payment overview on PayU, for support and finance.

-   Orders, refunds and payouts, from the PayU REST API and its notifications.
-   AI that spots orders that stay pending and drafts a reminder, with you approving what goes out.
-   A screen for support and a weekly email for finance.

### Ask your chat

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

-   Which orders from this week are still pending?
-   How much did we refund last month, and for which orders?

### When something happens

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

1.  When

    An order changes status, for example to canceled.

    AI decides

    AI looks at the order and drafts a short message with a new payment link.

    Then

    You approve it and the customer gets an email.

### A screen for your team or customers

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

-   For your team

    Support looks up an order by number and sees its payment status and refunds.

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

### Good to know

-   PayU signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for PayU takes more work: ask your chat to check this first.
-   Notifications are only sent when you pass a notifyUrl in the order request. This entry covers PayU GPO Europe (Poland and Czechia).
