What it takes to connect it to your AI chat with Hypamoon, with sources." url: https://hypamoon.com/connect-to/jtl-wawi --- 1. [Connect to](https://hypamoon.com/connect-to) 2. JTL-Wawi ERP and accounting # Connect JTL-Wawi to Hypamoon Possible, with help from JTL-Wawi. The API is documented, but you cannot just create a key: access goes through JTL-Wawi first. Possible ## The check Three questions about the API of JTL-Wawi, answered from its own docs. **Public API docs**\ **Yes.** Public developer portal for the JTL-Wawi API (on premises) and the JTL Cloud API. [Read the docs](https://developer.jtl-software.com/cloud/guides/essentials/common-patterns/versioning.md) **A key you create yourself**\ **Not confirmed.** The admin starts an app registration in JTL-Wawi and confirms it, after which a permanent API key is issued; the registration can also return 'no licence available or the app has not been authorised by JTL'. [developer.jtl-software.com](https://developer.jtl-software.com/api-reference/v1.0/appregistration/register-app.md) **Versions or a changelog**\ **Yes.** Numbered API versions (1.0 to 2.0) with an API changelog; on premises the version goes in the api-version header. [developer.jtl-software.com](https://developer.jtl-software.com/cloud/guides/essentials/common-patterns/versioning.md) **How it signs in**\ On premises: a permanent API key from the app registration in JTL-Wawi, sent as 'Authorization: Wawi ' with app headers. JTL Cloud: client credentials from the JTL Partner Portal for short-lived tokens. **Webhooks**\ **Yes.** It can tell your app when something changes. [developer.jtl-software.com](https://developer.jtl-software.com/cloud/guides/essentials/common-patterns/webhooks.md) **Hosting**\ Cloud and self-hosted **Condition**\ App registration must be confirmed in JTL-Wawi; JTL may require a licence or its own approval for the app. ## In practice What it takes in a real JTL-Wawi administration. **Getting access**\ An admin starts App registration in JTL-Wawi (new interface), your adapter sends the registration request, the admin confirms it, and the API returns a permanent key that is shown once. **Limits**\ None published. **Writing**\ **Not confirmed.** **Cost**\ Not published. ## Your own stock and order overview on JTL-Wawi, for the team and your business customers. - Items, stock, customers and sales orders from JTL-Wawi. - AI that spots slow movers and orders that wait too long. - A screen for the warehouse and a weekly email for you. ### Ask your chat Answers straight from your JTL-Wawi data, in Claude or another chat with the full Hypamoon connection. - Which items have not sold in the last 90 days? - Which sales orders from this week are not shipped yet? ### On a schedule An agent checks JTL-Wawi every 15 minutes and decides what happens next. 1. Every 15 minutes Stock levels in JTL-Wawi once a day. AI decides AI compares stock with recent sales and picks the items that need reordering. Then Purchasing gets one email with the list. ### A screen for your team or customers An app on your own address, with sign-in, on top of the same JTL-Wawi data. - For your team A screen in the warehouse with today's open orders and items that are low. JTL-Wawi 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 JTL-Wawi 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. - The JTL-Wawi API runs on your own Wawi server (a local address and port by default); you need a secure tunnel or gateway to reach it from the internet. JTL Cloud runs through api.jtl-cloud.com. - Pick API version 2.0 for a new build; many 1.x endpoints were removed in 2.0. ERP webhooks are described for JTL Cloud apps. ## Try it in your chat First get access from JTL-Wawi. Then fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for JTL-Wawi. API docs: https://developer.jtl-software.com/cloud/guides/essentials/common-patterns/versioning.md. Read: \[what\].
