Lengow Product data and marketplaces # Connect Lengow to Hypamoon Yes. Lengow 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 Lengow, answered from its own docs. **Public API docs**\ **Yes.** Public API documentation for orders, marketplaces and documents. [Read the docs](https://docs.lengow.io/) **A key you create yourself**\ **Yes.** The access token and secret are in the API section of your Lengow account, where you can also generate new ones.

[docs.lengow.io](https://docs.lengow.io/) **How it signs in**\ Your access token and secret are exchanged at /access/get\_token for a session token that is valid for one hour. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud ## Your own marketplace order overview on Lengow, for the shop and the warehouse. - Marketplace orders, order actions and invoice documents, straight from Lengow. - AI that spots orders that wait too long and tells the warehouse. - A screen for the warehouse and a daily email for you. ### Ask your chat Answers straight from your Lengow data, in Claude or another chat with the full Hypamoon connection. - Which marketplace orders from yesterday are not shipped yet? - Which marketplace had the most cancellations this month? ### On a schedule Lengow has no webhooks we could confirm, so an agent checks every 15 minutes and decides what happens next. 1. Every 15 minutes Orders in Lengow that are accepted but not shipped after a day. AI decides AI groups them per marketplace and checks the shipping deadline. Then The warehouse 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 Lengow data. - For your team A warehouse screen with open marketplace orders per channel. Lengow 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 Lengow 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 public API covers orders, order actions, marketplace information and documents, not your product catalogue. ## Try it in your chat Fill in what to read and write, and send it.
