Your own contract flow on BoldSign, from intake to a signed file in the right place.

  • Documents, templates, signers and their status, straight from BoldSign.
  • 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 BoldSign 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?

On a schedule

BoldSign has no webhooks we could confirm, so an agent checks every 15 minutes and decides what happens next.

  1. Every 15 minutes

    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 BoldSign data.

  • For your customers

    Customers sign in and find all their signed documents in one place.

BoldSign 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 BoldSign waits for your approval, one call at a time. How adapters work

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.

Try it in your chat

Fill in what to read and write, and send it.
