Monabanq API Access & Open Banking Integration

Monabanq is a French online bank, and open-banking.io lets you reach its account data without certificates, screen-scraping, or building against a bank API yourself. Whether you bank with Monabanq for personal or business needs, open-banking.io gives you one secure, standards-based route to your balances and transaction history — and keeps the encryption keys entirely in your hands.

Because open-banking.io is zero-knowledge, your financial data is decrypted locally on your own device with a key only you hold. The servers only ever store your public key, so no one at open-banking.io can read your Monabanq statements. Coverage spans 2,600+ EU and UK banks for around EUR 3/month.

How to connect Monabanq

Connecting happens entirely inside the open-banking.io dashboard — there is no code, API call, or key involved in this step:

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated right there on your device.
  2. In the dashboard, search for and select Monabanq, then choose the account type — business or personal.
  3. You are redirected to Monabanq's own secure login to approve access under PSD2 consent.
  4. Once approved, your Monabanq accounts sync straight into your dashboard.

Your PSD2 consent for Monabanq lasts up to 180 days, after which you simply re-approve from the same screen.

Access your data

After your Monabanq accounts are connected, developers can optionally read the data programmatically. On 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. Every request authenticates with the X-Api-Key header, and each response is decrypted locally with your own key. An API key on its own only ever returns ciphertext — the private key that turns it into readable data never leaves your machine.

FAQ

Does Monabanq have a BIC on open-banking.io?

No BIC is listed for Monabanq here, but that does not affect connecting — you select the bank by name in the dashboard.

Can I connect Monabanq using the CLI or an API key?

No. Connecting always happens in the dashboard via Monabanq's own consent screen. The CLI, SDK, and API only read or sync connections that already exist.

Can open-banking.io staff see my Monabanq transactions?

No. The service is zero-knowledge and holds only your public key. Data is decrypted locally with the private key that only you control.
