Connect e-conomic to Hypamoon

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

Possible

The check

Three questions about the API of e-conomic, answered from its own docs.

Public API docs
Yes. Public REST documentation and OpenAPI docs. Read the docs
A key you create yourself
No. Production access needs formal onboarding, identity verification and a signed developer agreement per application, and e-conomic may deny access. e-conomic.com
Versions or a changelog
Yes. Each OpenAPI has its own version, and a previous major version stays supported for at least 12 months; the older REST API is in feature freeze. e-conomic.dk
How it signs in
Two tokens in headers: an app secret token for your app and an agreement grant token that the e-conomic customer issues when installing the app.
Webhooks
Yes. It can tell your app when something changes. e-conomic.com
Hosting
Cloud
Condition
Production access needs onboarding and approval by e-conomic, for a business with a CVR number or a foreign equivalent.

In practice

What it takes in a real e-conomic administration.

Getting access
You sign up for a free developer agreement, create an app, go through e-conomic's onboarding and identity check, and the customer installs the app on their agreement to issue the grant token.
Limits
A token bucket per agreement, where each endpoint costs tokens; e-conomic does not publish fixed numbers on its fair use page. e-conomic.com
Writing
Read and write. Create records with POST, for example draft invoices and customer groups.
Cost
The development environment is free; e-conomic can introduce fees with 60 days notice. e-conomic.com

Your own customer portal on e-conomic, with invoices and statements in one place.

  • Customers, draft and booked invoices, products and accounts, through the e-conomic APIs.
  • AI that prepares draft invoices from orders and follows up late payers, with you approving every change.
  • A portal for your customers and a short weekly email for you.

Ask your chat

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

  • Which customers have booked invoices that are past due?
  • What did we invoice per product this month?

When something happens

e-conomic sends a webhook to your app for some events, and the app asks AI what happens next. For the rest an agent checks every 15 minutes.

  1. When

    An invoice is booked in e-conomic.

    AI decides

    AI looks at the customer's payment history and decides if a friendly reminder plan is needed.

    Then

    You get an email with the advice and a draft text.

  2. Every 15 minutes

    New orders from your own web form that are not invoiced yet.

    AI decides

    AI matches the customer and the products and checks the prices.

    Then

    A draft invoice is created in e-conomic.

    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 e-conomic data.

  • For your customers

    Customers sign in and see their own invoices and download them, straight from e-conomic.

e-conomic 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 e-conomic 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.
  • New production apps start with a quota of 20 installations, after which e-conomic verifies them manually. Rate limiting works with a token bucket per agreement.
