What your AI chat can build with it on Hypamoon, with sources." url: https://hypamoon.com/connect-to/katana --- 1. [Connect to](https://hypamoon.com/connect-to) 2. Katana ERP and accounting # Connect Katana to Hypamoon Yes. Katana 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 Katana, answered from its own docs. **Public API docs**\ **Yes.** Public developer portal with guides, reference and changelog. [Read the docs](https://developer.katanamrp.com/) **A key you create yourself**\ **Yes.** Create a key yourself under Settings, API, API keys. [developer.katanamrp.com](https://developer.katanamrp.com/docs/getting-started) **Versions or a changelog**\ **Yes.** Katana publishes an API changelog, including breaking changes. [developer.katanamrp.com](https://developer.katanamrp.com/changelog) **How it signs in**\ An API key you create in Katana settings, sent as a Bearer token; OAuth 2.0 is there for apps. **Webhooks**\ **Yes.** It can tell your app when something changes. [developer.katanamrp.com](https://developer.katanamrp.com/reference/webhooks) **Hosting**\ Cloud **Condition**\ API keys need the Professional plan or higher. ## In practice What it takes in a real Katana administration. **Getting access**\ An admin on the Professional plan or higher creates an API key under Settings, API, API keys and copies it from the pop up. **Limits**\ 60 requests per 60 seconds by default. [developer.katanamrp.com](https://developer.katanamrp.com/reference/api-rate-limiting) **Writing**\ **Read and write.** Create, update and delete records such as customers, sales orders, purchase orders and manufacturing orders. **Cost**\ No separate API fee; the API needs the Professional plan or higher. [developer.katanamrp.com](https://developer.katanamrp.com/docs/getting-started) ## Your own order portal and production overview on Katana, built around your workshop. - Products, materials, stock, sales, purchase and manufacturing orders, straight from Katana. - AI that spots materials that run low and orders at risk of running late. - A portal for your customers and a weekly email for you. ### Ask your chat Answers straight from your Katana data, in Claude or another chat with the full Hypamoon connection. - Which sales orders are waiting on materials we have not ordered yet? - Which manufacturing orders are blocked right now? ### When something happens Katana 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 product goes out of stock in Katana. AI decides AI checks which open sales orders it affects and how soon the next batch is due. Then The planner gets an email with the orders at risk. 2. Every 15 minutes New orders in your own order page that are not in Katana yet. AI decides AI checks the products, quantities and customer details and flags anything odd. Then A sales order is created in Katana. 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 Katana data. - For your customers Customers sign in and see their orders and the expected delivery date from Katana. Katana 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 Katana 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. - Keep the API key on a server; Katana warns against using it in a browser app. ## Try it in your chat Fill in what to read and write, and send it.
