Connect Powens to Hypamoon

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

Possible

The check

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

Public API docs
Yes. Powens publishes a quick start, integration guides, an API reference and a changelog. Read the docs
A key you create yourself
No. You sign up for the console and create a sandbox domain and client ID and secret yourself, but a production environment needs a signed contract. docs.powens.com
Versions or a changelog
Yes. Powens publishes a changelog of new releases and features. docs.powens.com
How it signs in
A client ID and secret per client application, and a user access token per end user after they connect their bank through the Powens webview.
Webhooks
Yes. It can tell your app when something changes. docs.powens.com
Hosting
Cloud
Condition
Production needs a signed contract with Powens.

What you can build

Pull the transactions of all your bank accounts into your own app through Powens and match incoming payments to open invoices.

Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write 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.
  • Powens is a licensed aggregator for bank accounts, payments and documents such as invoices, mainly in France and Europe. Webhooks push new data to your server.

Try it in your chat

First get access from Powens. 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.
