Connect Fakturoid to Hypamoon

Yes, with one catch. Fakturoid 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 Fakturoid, answered from its own docs.

Public API docs
Yes. Read the docs
A key you create yourself
Yes. Client ID and secret for the client credentials flow are in Settings > User account; apps register under Settings > Connect other apps. fakturoid.cz
Versions or a changelog
Yes. Versioned API (v3) with a dated changelog. fakturoid.cz
How it signs in
OAuth 2.0 client credentials from your user settings give an access token for 2 hours, with no refresh token; the authorization code flow is for apps used by other accounts.
Webhooks
Yes. It can tell your app when something changes. fakturoid.cz
Hosting
Cloud
Condition
Webhooks are only available on paid Fakturoid plans.

In practice

What it takes in a real Fakturoid administration.

Getting access
You take the client ID and secret from Settings > User account in Fakturoid and request an access token with the client credentials flow.
Limits
The docs show a policy of 400 requests per 60 seconds in the rate limit headers; above that the API answers 429. fakturoid.cz
Writing
Read and write. Create invoices with POST and update them with PATCH, among other records.
Cost
Not published.

Your own client portal on Fakturoid, with invoices and payments in one place.

  • Subjects, invoices, expenses, recurring generators and inventory, straight from Fakturoid.
  • AI that drafts invoices from orders and follows up overdue invoices, with you approving every change.
  • A portal for your clients and a short weekly email for you.

Ask your chat

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

  • Which invoices are overdue, and for how many days?
  • How much did we spend per supplier this quarter?

When something happens

Fakturoid sends a webhook to your app for some events, and the app asks AI what happens next. For the rest an agent checks every 15 minutes.

  1. When

    An invoice becomes overdue.

    AI decides

    AI looks at the client's payment history and picks between a friendly note and waiting a week.

    Then

    You get an email with the advice and a draft text.

  2. Every 15 minutes

    New orders from your own web form that are not invoiced yet.

    AI decides

    AI matches the client and the items and checks the VAT.

    Then

    An invoice is created in Fakturoid.

    AI proposes, you approve

A screen for your team or customers

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

  • For your customers

    Clients sign in and see their own invoices and payment status, straight from Fakturoid.

Fakturoid 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 Fakturoid waits for your approval, one call at a time. How adapters work

Good to know

  • Fakturoid signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Fakturoid takes more work: ask your chat to check this first.
  • Access tokens last 2 hours and have to be requested again with the client credentials. The limit is 400 requests per 60 seconds.
