VakifBank International Open Banking API Access

Reaching your VakifBank International accounts programmatically usually means wrestling with PSD2 certificates, sandbox registrations, and TPP paperwork. open-banking.io removes all of that. It is a zero-knowledge, certificate-free gateway to 2,600+ EU and UK banks, so you can pull balances and transactions from VakifBank International (BIC TVBADEFFXXX) without ever running your own bank integration.

The design principle is simple: your data belongs to you. When you join, encryption keys are generated on your own device, and everything that syncs back is decrypted locally with a key that only you hold. open-banking.io's servers keep just your public key, so they can store ciphertext but never read it.

How to connect VakifBank International

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

  1. Sign up for open-banking.io and set your encryption passphrase; this generates your personal keys locally.
  2. Open the dashboard and search for VakifBank International.
  3. Choose the account type you need — both business and personal accounts are supported.
  4. You are redirected to VakifBank International's own secure login to approve access under PSD2. Your credentials stay with the bank.
  5. Once you grant consent, your accounts sync into the dashboard. Consent lasts up to 180 days, after which you simply re-approve.

Access your data

Programmatic access is an optional developer step you take after the bank is connected. On the Developers page, create an API key and export a credentials.json file — it bundles the API key together with your private decryption key. From there you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly.

Every request authenticates with the X-Api-Key header, and each response is decrypted locally with your private key. That is why the API key alone is never enough to expose readable data: without your key you only ever receive ciphertext. The CLI and SDKs read and sync connections you already approved — they cannot create one.

All of this runs for about EUR 3/month, with no certificate costs or TPP licensing.

Do I need a PSD2 certificate?

No. open-banking.io is certificate-free — approving consent on VakifBank International's login screen is all that is required.

Can open-banking.io read my VakifBank International data?

No. It is zero-knowledge and stores only your public key. Decryption happens on your device with a key only you hold.

Can I connect the account from the CLI?

No. Connecting is a dashboard-only flow. The CLI, SDK, and API only read and sync existing connections.
