Argenta API Access & Open Banking Integration
Managing money across current and savings accounts at Argenta means logging into a different app every time you want the full picture. open-banking.io removes that friction. It gives you a single, secure dashboard that reads your Argenta balances and transactions under PSD2 — with none of the eIDAS certificates, sandbox registrations, or bank-by-bank paperwork that a direct integration would demand. Whether you hold a personal account or run a business, your Argenta data flows into one place and stays encrypted with a key that never leaves your device.
Argenta (BIC ARSPBE22) is fully supported, and consent lasts up to 180 days before Argenta asks you to re-approve.
How to connect Argenta
Connecting happens entirely inside the open-banking.io dashboard — there is no code, endpoint, or API key involved in this step.
- Sign up at open-banking.io and set an encryption passphrase. Your keys are generated locally, on your own device.
- In the dashboard, pick Argenta from the list of 2,600+ supported banks and choose your account type — business or personal.
- You are redirected to Argenta's own secure login, where you approve access directly on the bank's PSD2 consent screen.
- Your accounts sync back into the dashboard, and balances plus transactions appear ready to view.
Because you authenticate on Argenta's own pages, open-banking.io never sees your banking credentials.
Access your data
Reading Argenta data programmatically is an optional step you take after the connection exists. Open the Developers page, create an API key, and export a credentials.json — this bundles the API key together with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests carry your key in the X-Api-Key header, and every response is decrypted locally with your own key. The servers only ever hold your public key, so an API key alone returns ciphertext — the readable data is assembled on your machine.
FAQ
Does open-banking.io store my Argenta login?
No. You approve access on Argenta's own consent screen, and the platform is zero-knowledge — it holds only your public key and can never read or decrypt your accounts.
How often do I re-authorise Argenta?
Argenta grants consent for up to 180 days. Near expiry you simply repeat the dashboard approval to keep data flowing.
What does it cost?
Around EUR 3 per month for full access to Argenta and every other supported bank — no per-connection or certificate fees.
