What your AI chat can build with it on Hypamoon, with sources." url: https://hypamoon.com/connect-to/recommand --- 1. [Connect to](https://hypamoon.com/connect-to) 2. Recommand Payments and billing # Connect Recommand to Hypamoon Yes. Recommand 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 Recommand, answered from its own docs. **Public API docs**\ **Yes.** [Read the docs](https://docs.recommand.eu/) **A key you create yourself**\ **Yes.** Sign up at app.recommand.eu; the free plan includes 25 documents a month with API and dashboard access. [docs.recommand.eu](https://docs.recommand.eu/) **Versions or a changelog**\ **Yes.** Versioned path /api/v1 with a dated changelog and an OpenAPI specification. [docs.recommand.eu](https://docs.recommand.eu/) **How it signs in**\ An API key and secret with Basic auth, or a JWT; OAuth2 with a JWT assertion is also supported. **Webhooks**\ **Yes.** It can tell your app when something changes. [docs.recommand.eu](https://docs.recommand.eu/) **Hosting**\ Cloud ## Your own Peppol invoice flow on Recommand, built around your bookkeeping. - Sending and receiving Peppol invoices, with webhooks for what comes in. - AI that reads incoming invoices and proposes the cost category, with a person approving. - A screen for your team and an email when an invoice is rejected. ### Ask your chat Answers straight from your Recommand data, in Claude or another chat with the full Hypamoon connection. - Which purchase invoices arrived over Peppol this week? - Which sent invoices were not delivered? ### When something happens Recommand sends a webhook to your app, and the app asks AI what happens next. 1. When A new invoice arrives over Peppol. AI decides AI reads it and suggests the supplier, cost category and due date. Then Your team gets an email to approve the booking. ### A screen for your team or customers An app on your own address, with sign-in, on top of the same Recommand data. - For your team Your team sees incoming and outgoing Peppol invoices and their delivery status. ### Add Hypamoon Text messages, email, phone, payments and agents run in the same project as the adapter. - Agent on a schedule An agent sends an approved sales invoice over Peppol after you click approve. AI proposes, you approve Recommand 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 Recommand 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. - One team has one API key, and the volume of all companies under it is pooled. A playground team lets you test without real Peppol delivery. Webhook deliveries can be signed with an X-Signature header. ## Try it in your chat Fill in what to read and write, and send it.
