Crédit Agricole Martinique Guyane open banking

Reaching your Crédit Agricole de la Martinique et de la Guyane accounts programmatically usually means wrestling with PSD2 sandboxes, eIDAS certificates and rejected registrations. open-banking.io removes all of that. It covers 2,600+ banks across the EU and UK, including this Antilles-Guyane regional caisse of the Crédit Agricole group, and it hands you clean account and transaction data without a single certificate or bank contract.

Both business and personal accounts are supported, and a single consent stays valid for up to 180 days before Crédit Agricole de la Martinique et de la Guyane asks you to re-approve. (No public BIC is listed for this entity — you select it directly by name in the dashboard, so you never need to look one up.)

How to connect Crédit Agricole de la Martinique et de la Guyane

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

  1. Sign up at open-banking.io and set your encryption passphrase. Your keys are generated locally on your own device, so only you can ever decrypt what comes back.
  2. In the dashboard, pick Crédit Agricole de la Martinique et de la Guyane from the bank list and choose the account type — business or personal.
  3. You are redirected to Crédit Agricole de la Martinique et de la Guyane's own secure login, where you approve access (standard PSD2 consent) on the bank's screen — your credentials never touch open-banking.io.
  4. Your accounts sync straight into the dashboard, ready to view or export.

Access your data

Once the connection exists, developers can optionally read it in code. On the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. Then use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command.

Because open-banking.io is zero-knowledge, its servers hold only your public key. An API key alone returns ciphertext; without your private key it stays unreadable — even to us. All of this runs for around EUR 3/month.

Is a bank contract or certificate required?

No. open-banking.io is certificate-free — you approve access on the bank's consent screen and nothing else.

Can I connect a business account?

Yes. Both business and personal Crédit Agricole de la Martinique et de la Guyane accounts are supported.

How long does access last?

Up to 180 days per consent, after which you simply re-approve in the dashboard.
