Fatture in Cloud ERP and accounting # Connect Fatture in Cloud to Hypamoon Yes. Fatture in Cloud 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 Fatture in Cloud, answered from its own docs. **Public API docs**\ **Yes.** [Read the docs](https://developers.fattureincloud.it/docs/getting-started) **A key you create yourself**\ **Yes.** The user generates an access token in Settings > Connected Applications for an app's Client ID, picks the companies and permissions, and the token does not expire. [developers.fattureincloud.it](https://developers.fattureincloud.it/docs/authentication/manual-authentication/) **Versions or a changelog**\ **Yes.** Versioned API (v2) with a public changelog. [developers.fattureincloud.it](https://developers.fattureincloud.it/docs/CHANGELOG) **How it signs in**\ A manually generated access token as a Bearer token, which does not expire until you revoke it; OAuth 2.0 for apps used by other accounts. **Webhooks**\ **Yes.** It can tell your app when something changes. [developers.fattureincloud.it](https://developers.fattureincloud.it/docs/webhooks/) **Hosting**\ Cloud ## 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](https://developers.fattureincloud.it/docs/basics/limits-and-quotas/) **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](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. - Private apps share 1,000 requests per hour and 40,000 per month per company, and all apps together 300 requests per 5 minutes. ## Try it in your chat Fill in what to read and write, and send it.
