What your AI chat can build with it on Hypamoon, with sources." url: https://hypamoon.com/connect-to/rompslomp --- 1. [Connect to](https://hypamoon.com/connect-to) 2. Rompslomp ERP and accounting # Connect Rompslomp to Hypamoon Yes. Rompslomp 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 Rompslomp, answered from its own docs. **Public API docs**\ **Yes.** Public developer documentation in Dutch. [Read the docs](https://app.rompslomp.nl/developer) **A key you create yourself**\ **Yes.** Create a personal API token under My account, My API tokens, and pick the sections it may use. [app.rompslomp.nl](https://app.rompslomp.nl/developer/api-tokens) **Versions or a changelog**\ **Yes.** Versioned base path, /api/v1. [app.rompslomp.nl](https://app.rompslomp.nl/developer/algemeen) **How it signs in**\ A personal API token sent as a Bearer token; it stays valid until you delete it. OAuth 2.0 is for apps that other Rompslomp users authorise. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud **Condition**\ Needs at least a Puur Factuur account, and the owner of the administration has to switch on the API function. ## Your own invoicing flow on Rompslomp, from your site straight to your books. - Contacts, sales invoices, quotes and products, straight from Rompslomp. - AI that turns a web request into a draft invoice for you to approve. - An order form on your own site and an email when something needs a look. ### Ask your chat Answers straight from your Rompslomp data, in Claude or another chat with the full Hypamoon connection. - Which sales invoices are still unpaid, and since when? - How much did we invoice this quarter compared to last quarter? ### On a schedule Rompslomp has no webhooks we could confirm, so an agent checks every 15 minutes and decides what happens next. 1. Every 15 minutes New requests from the order form on your own site. AI decides AI matches the request to an existing contact and picks the right products and VAT rate. Then A draft sales invoice is created in Rompslomp for you to check. 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 Rompslomp data. - For your customers Customers sign in and see their own invoices and quotes from Rompslomp. Rompslomp 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 Rompslomp 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. - A token can only reach what your own user can reach in the administration. The API answers 429 with a Retry-After header when you go over the rate limit. Undocumented functions may change without notice. ## Try it in your chat Fill in what to read and write, and send it.
