Bethmann Bank API Access: Sync Accounts via Open Banking

Pulling account data out of Bethmann Bank no longer means wrestling with eIDAS certificates or bespoke bank integrations. With open-banking.io you point a single REST endpoint at Bethmann Bank (BIC DELBDE33XXX) and start syncing live financial data into your own product, ledger or reporting stack. The private-banking arm serves both business and personal relationships, and both account types are reachable through the same interface.

How to connect Bethmann Bank

1. Create an open-banking.io account and generate an API key.
2. Call the institutions endpoint and select Bethmann Bank (Germany).
3. Send your customer to the hosted consent screen to authenticate directly with the bank.
4. Receive the returned consent token and begin requesting data.
5. Refresh on your own schedule until the consent window closes.

What data you can access

Once a customer approves the link, the API exposes their accounts (IBANs, currency, product metadata), real-time balances including available and booked figures, and dated transaction history with counterparties and remittance details. Everything arrives as clean, normalised JSON, so a Bethmann Bank account looks identical in your code to any of the other institutions you connect.

Consent and coverage

A single authorisation stays valid for up to 180 days before the customer needs to re-approve, giving you long-lived read access without constant re-prompts. Bethmann Bank is one node in a network of 2,600+ banks across the EU and UK, so the same integration scales the moment you add a second institution.

Privacy by design

The platform is zero-knowledge: credentials are entered only on the bank's own domain, and we never store or relay them. There are no QWAC or QSEAL certificates to buy, renew or install — the compliance and PSD2 plumbing sits entirely on our side, so your team ships instead of provisioning.

Pricing

Access starts at roughly EUR 3 per month, a flat, predictable rate rather than per-call metering or enterprise contracts.

Is a certificate required to use the Bethmann Bank API?

No. The service is certificate-free — no eIDAS QWAC/QSEAL setup is needed on your end.

How long does Bethmann Bank consent last?

Up to 180 days per authorisation, after which the customer simply reconfirms access.

Can I read both business and personal accounts?

Yes. Both account types Bethmann Bank offers are supported through the same endpoints.
