In practice

What it takes in a real Fatture in Cloud administration.

Getting access
You create an app in the developer area to get a Client ID, then generate an access token for it in Settings > Connected Applications, choosing the companies and permissions.
Limits
300 requests per 5 minutes per company; 1,000 per hour and 40,000 per month per company for private apps, and the same per company and app for public apps. developers.fattureincloud.it
Writing
Read and write. Create issued documents such as invoices with POST /c/{company_id}/issued_documents, among other records.
Cost
Not published.

Your own client portal on Fatture in Cloud, with quotes and invoices in one place.

  • Clients, issued documents, received documents and products, straight from Fatture in Cloud.
  • AI that turns orders into draft invoices and follows up late payments, with you approving every change.
  • A portal for your clients and a short weekly email for you.

Ask your chat

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

  • Which invoices are unpaid after their due date?
  • How much did we invoice per client this year?

When something happens

Fatture in Cloud 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

    A received document from a supplier is added.

    AI decides

    AI reads it and compares it with earlier documents from the same supplier.

    Then

    You get an email when the amount or the terms look different.

  2. Every 15 minutes

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

    AI decides

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

    Then

    An issued document is created in Fatture in Cloud.

    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 Fatture in Cloud data.

  • For your customers

    Clients sign in and see their own quotes and invoices, straight from Fatture in Cloud.

Fatture in Cloud 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 Fatture in Cloud 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.
  • Private apps share 1,000 requests per hour and 40,000 per month per company, and all apps together 300 requests per 5 minutes.
