Connect Octopus to Hypamoon

Possible, with help from Octopus. The API is documented, but you cannot just create a key: access goes through Octopus first.

Possible

The check

Three questions about the API of Octopus, answered from its own docs.

Public API docs
Yes. Public manual for the Octopus webservice with Swagger reference documentation. Read the docs
A key you create yourself
No. Every integration needs a software house ID, which you request by email from Octopus, on top of user credentials or an OAuth token. login.octopus.be
Versions or a changelog
Yes. The REST API runs under a versioned path (/octopus-rest-api/v1) with a version endpoint. login.octopus.be
How it signs in
The software house ID plus the user name and password of an Octopus user give a token that is valid for 10 minutes; OAuth tokens are also possible.
Webhooks
Not confirmed.
Hosting
Cloud
Condition
A software house ID from Octopus, and a user with the webservice module switched on.

In practice

What it takes in a real Octopus administration.

Getting access
Email support@octopus.be or webservice@octopus.be for a software house ID, then sign in with an Octopus user that has the webservice module, or use an OAuth token.
Limits
Octopus applies a rate limit but publishes no numbers; integrations that exceed it get an email and are expected to optimise. login.octopus.be
Writing
Read and write. Add bookings, relations and other records in a dossier through the REST API; invoice inserts need the invoice module in that dossier.
Cost
For external users (U and K) the webservice module is included in the monthly fee; accountancy office users (B) activate it separately. login.octopus.be

Your own finance overview on Octopus, for you and your bookkeeper.

  • Accounts, relations, bookings and open items from the dossiers you can reach.
  • AI that spots customers who start paying late and prepares the booking for you to approve.
  • A screen for your team and a weekly email for you.

Ask your chat

Answers straight from your Octopus data, in Claude or another chat with the full Hypamoon connection.

  • Which customers have open items older than 60 days?
  • What is the balance on our main bank account this week?

On a schedule

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

  1. Every 15 minutes

    Open items in the dossier that pass their due date.

    AI decides

    AI groups them per customer and writes a short, friendly reminder text.

    Then

    You get one email with the list and the draft reminders.

A screen for your team or customers

An app on your own address, with sign-in, on top of the same Octopus data.

  • For your team

    A screen with open items per customer from your Octopus dossier.

Octopus 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 Octopus 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.
  • You work per dossier: after signing in you request a dossier token for the dossier you want. Octopus advises importing bookings rather than invoices from external programs.

Try it in your chat

First get access from Octopus. Then fill in what to read and write, and send it.

The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.
