Documenso Files and e-signing # Connect Documenso to Hypamoon Yes. Documenso 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 Documenso, answered from its own docs. **Public API docs**\ **Yes.** Open source e-signing with a public API; self-hosted instances use the same API on their own URL. [Read the docs](https://docs.documenso.com/developers/public-api) **A key you create yourself**\ **Yes.** Create an API token yourself in your team settings under API Tokens; included on all plans, also Free. [docs.documenso.com](https://docs.documenso.com/developers/public-api/authentication) **Versions or a changelog**\ **Yes.** Versioned API (/api/v2) with a separate versioning page.

[docs.documenso.com](https://docs.documenso.com/developers/public-api) **Hosting**\ Cloud and self-hosted ## Your own contract flow on Documenso, from intake to a signed file in the right place. - Documents, templates, signers and their status, straight from Documenso. - AI that fills the document from the intake and checks who still has to sign. - An intake page on your own site, and a short email when everything is signed. ### Ask your chat Answers straight from your Documenso data, in Claude or another chat with the full Hypamoon connection. - Which documents sent last week are still waiting for a signature? - Who signed the rental agreement, and when? ### When something happens Documenso sends a webhook to your app, and the app asks AI what happens next. 1. When A document is fully signed. AI decides AI reads the document and picks the customer and the folder it belongs to. Then The signed file is stored with the customer in your app, and the account manager gets an email. ### A screen for your team or customers An app on your own address, with sign-in, on top of the same Documenso data. - For your customers Customers sign in and find all their signed documents in one place. Documenso 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 Documenso 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. - If you host it yourself, the API of your own installation must be reachable over HTTPS from the internet, so the adapter can call it. - The free plan is limited to 5 documents per month. ## Try it in your chat Fill in what to read and write, and send it.
