La Banque Postale API Access & Open Banking Sync

Pulling your La Banque Postale balances and transactions into your own tools usually means wrestling with PSD2 certificates, sandbox registrations and OAuth scopes. open-banking.io removes that layer entirely. You link La Banque Postale once through a guided dashboard, and your account data flows in encrypted — decrypted only on your own device with a key nobody else holds.

The service covers both business and personal La Banque Postale accounts (BIC PSSTFRPPBOR), with a PSD2 consent that stays valid for up to 180 days before you re-approve. No eIDAS certificate, no developer onboarding, no bank-side paperwork.

How to connect La Banque Postale

Connecting happens visually in the open-banking.io dashboard — there is no API call or key involved at this stage:

  1. Create your open-banking.io account and set an encryption passphrase. Your key pair is generated locally on your device; open-banking.io only ever sees your public key.
  2. In the dashboard, search for La Banque Postale and choose whether you're linking a business or personal account.
  3. You're redirected to La Banque Postale's own secure login, where you approve access on the bank's official PSD2 consent screen.
  4. Once approved, your accounts and transactions sync back into your dashboard, ready to view or export.

That's the whole flow — you authenticate directly with La Banque Postale, and open-banking.io never touches your banking credentials.

Access your data

Want the data in code? That's an optional step after the connection exists. Open the Developers page, create an API key, and download a credentials.json — it bundles the API key together with your private decryption key. From there:

  • CLI: openbanking accounts, openbanking transactions, openbanking sync
  • SDK or REST API for your own integrations

Every request authenticates with the X-Api-Key header, and each response is decrypted locally using your private key. Without that key an API key alone returns only ciphertext — the servers can't read it, and neither can anyone who intercepts it. Note the CLI and SDK only read and refresh existing connections; the initial La Banque Postale link is always made in the dashboard.

All of this runs for around EUR 3/month, across 2,600+ supported EU and UK banks.
