Connect N26 Business to Hypamoon
Possible, with help from N26 Business. The API is documented, but you cannot just create a key: access goes through N26 Business first.
PossibleThe check
Three questions about the API of N26 Business, answered from its own docs.
- Public API docs
- Yes. N26 publishes its PSD2 interface documentation, an OpenAPI file, a sandbox Postman collection and an FAQ on GitHub. Read the docs
- A key you create yourself
- No. The PSD2 APIs are for licensed third party providers with an eIDAS certificate. N26 offers no API key for its own business customers. github.com
- Versions or a changelog
- Yes. Changes are published as dated key announcements per year for the dedicated and fallback interfaces. github.com
- How it signs in
- OAuth 2.0 with the consent of the account holder, identified with an eIDAS certificate as a licensed provider.
- Webhooks
- Not confirmed.
- Hosting
- Cloud
- Condition
- Only licensed PSD2 providers can connect. A normal company reads its N26 Business account through a licensed aggregator, such as Enable Banking (https://enablebanking.com/docs/api/linked-accounts/); check that it covers N26.
What you can build
See the transactions of your N26 Business account in your own bookkeeping app through an aggregator, and match receipts to payments.
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
- N26 Business signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for N26 Business takes more work: ask your chat to check this first.
- N26 has PSD2 interfaces only. The FAQ answers whether they differ for retail and business accounts.
Try it in your chat
First get access from N26 Business. Then fill in what to read and write, and send it.
Build the Hypamoon recipe build-an-adapter for N26 Business. API docs: https://github.com/n26/psd2-tpp-docs. Read: [what]. Write: [what, or nothing].
In Claude, or another chat with the full Hypamoon connection; adapters are not in ChatGPT yet. You paste the key in the portal, never in the chat. The full recipe

Tool not listed? Ask the chat to check its API.
The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.
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.
Fill in the name of your software. Checking needs no connection to Hypamoon.
