Connect Reviso to Hypamoon

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

Possible

The check

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

Public API docs
Yes. Read the docs
A key you create yourself
No. You first email api@reviso.com for a free developer account; the customer then grants your app access, which gives an agreement grant token. reviso.com
Versions or a changelog
Not confirmed.
How it signs in
Two headers on every call: X-AppSecretToken from your developer agreement and X-AgreementGrantToken from the customer who grants access.
Webhooks
Yes. It can tell your app when something changes. reviso.com
Hosting
Cloud
Condition
A free developer account, requested by email at api@reviso.com.

In practice

What it takes in a real Reviso administration.

Getting access
Email api@reviso.com for a free developer account, create an app in the Developer tab for the app secret token, and let the customer grant access to get the agreement grant token.
Limits
None published.
Writing
Not confirmed. Not confirmed from the pages that could be opened; the demo mode allows only GET.
Cost
The developer account is free. reviso.com

Your own customer portal on Reviso, built around how your customers ask for things.

  • Customers, invoices and open balances, once Reviso has given you a developer account.
  • AI that spots late payers and drafts a reminder, with you approving each one.
  • A portal for your customers and a short weekly email for you.

Ask your chat

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

  • Which customers have invoices more than 30 days overdue?
  • What did we invoice per customer this quarter?

When something happens

Reviso sends a webhook to your app, and the app asks AI what happens next.

  1. When

    Reviso sends an event you subscribed to, such as a new booked invoice.

    AI decides

    AI checks the customer's payment history and decides whether to watch this invoice.

    Then

    The account owner gets an email when a reminder is due.

A screen for your team or customers

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

  • For your customers

    Customers sign in and see their invoices and what is still open.

Add Hypamoon

Text messages, email, phone, payments and agents run in the same project as the adapter.

  • Agent on a schedule

    Once a week, an agent emails you the customers who pay later than they used to.

Reviso 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 Reviso 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.
  • A demo mode lets you try GET requests without a developer agreement.

Try it in your chat

First get access from Reviso. 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.

Say this in your chat

Check if [software] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
