What your AI chat can build with it on Hypamoon, with sources." url: https://hypamoon.com/connect-to/qonto --- 1. [Connect to](https://hypamoon.com/connect-to) 2. Qonto ERP and accounting # Connect Qonto to Hypamoon Yes. Qonto 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 Qonto, answered from its own docs. **Public API docs**\ **Yes.** Public developer docs for the Business API with guides and a reference. [Read the docs](https://docs.qonto.com/guides/authentication/api-key) **A key you create yourself**\ **Yes.** You generate a secret key yourself under Integrations and Partnerships, API key. [docs.qonto.com](https://docs.qonto.com/guides/authentication/api-key) **Versions or a changelog**\ **Yes.** Versioned paths such as /v2, with a new version for each breaking change. [docs.qonto.com](https://docs.qonto.com/api-reference/business-api/introduction/versioning) **How it signs in**\ Your organisation sign-in and secret key joined with a colon in the Authorization header; OAuth 2.0 for the endpoints the key cannot reach. **Webhooks**\ **Yes.** It can tell your app when something changes. [docs.qonto.com](https://docs.qonto.com/guides/webhooks/setup) **Hosting**\ Cloud **Condition**\ The API key reaches a subset of endpoints, mostly read-only; the rest needs OAuth 2.0. ## In practice What it takes in a real Qonto administration. **Getting access**\ In the Qonto web app, open Integrations and Partnerships, API key, click Generate and use your sign-in plus the secret key. **Limits**\ 1,000 requests per 10 seconds and 10,000 requests per 10 minutes, per IP address. [docs.qonto.com](https://docs.qonto.com/api-reference/business-api/introduction/rate-limits) **Writing**\ **Read and write.** The API can write, but the API key reaches mostly read-only endpoints; most write actions need OAuth 2.0. **Cost**\ Not published. ## Your own cash overview on Qonto, for you and your bookkeeper. - Accounts, balances, transactions and attachments, straight from Qonto. - AI that flags transactions without a receipt and asks the right person. - A screen for the office and a weekly email for you. ### Ask your chat Answers straight from your Qonto data, in Claude or another chat with the full Hypamoon connection. - Which card payments this month have no receipt attached? - What did we spend on software last quarter? ### When something happens Qonto sends a webhook to your app, and the app asks AI what happens next. 1. When A new transaction appears on a Qonto account. AI decides AI checks whether it needs a receipt and who made it. Then That person gets an email asking for the receipt. ### A screen for your team or customers An app on your own address, with sign-in, on top of the same Qonto data. - For your team A screen with balances and the latest transactions per account. ### Add Hypamoon Text messages, email, phone, payments and agents run in the same project as the adapter. - Agent on a schedule Every Friday, an agent emails you the transactions still missing a receipt. Qonto 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 Qonto 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. - Rate limits are 1,000 requests per 10 seconds and 10,000 per 10 minutes, per IP address. ## Try it in your chat Fill in what to read and write, and send it.
