Connect Silverfin to Hypamoon

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

Possible

The check

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

Public API docs
Yes. Read the docs
A key you create yourself
No. The OAuth client ID is requested by email at api@getsilverfin.com. developer.silverfin.com
Versions or a changelog
Yes. Version 4 is the supported stable version; older versions are documented as deprecated. developer.silverfin.com
How it signs in
OAuth 2.0 authorization code flow with a client ID and secret you request from Silverfin; access tokens last two hours and refresh tokens work once.
Webhooks
Not confirmed.
Hosting
Cloud
Condition
The OAuth client is requested from Silverfin by email.

In practice

What it takes in a real Silverfin administration.

Getting access
Email api@getsilverfin.com to request an OAuth client ID and secret, then let a Silverfin user of the firm authorize your app.
Limits
3,000 requests per minute per firm, and 300 per minute on the token endpoint; over the limit you get a 429 with Retry-After. developer.silverfin.com
Writing
Not confirmed. Write scopes are mentioned in the scope list, but write support was not confirmed on the pages read.
Cost
Not published.

Your own overview of client files on Silverfin, built around how your office closes the year.

  • Companies, periods, workflows and reconciliations, once Silverfin has issued your client.
  • AI that spots files that fall behind and decides who should pick them up, with you approving every step.
  • A screen for your team and a short weekly email.

Ask your chat

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

  • Which client files still have open workflows for last year?
  • Which companies have unreconciled accounts this period?

On a schedule

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

  1. Every 15 minutes

    Every Friday afternoon.

    AI decides

    AI looks at open workflows per file and decides which ones need attention first.

    Then

    Each colleague gets an email with their files for next week.

A screen for your team or customers

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

  • For your team

    Your team sees progress per client file and per colleague.

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

Good to know

  • Silverfin signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Silverfin takes more work: ask your chat to check this first.
  • The limit is 3,000 requests per minute per firm. A webhooks scope exists, but how webhooks work is not described on the pages checked.

Try it in your chat

First get access from Silverfin. 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.
