Grong Sparebank API Access — Open Banking Made Simple

Pulling live data out of your Grong Sparebank accounts no longer means wrestling with bank-specific integrations. open-banking.io gives developers and finance teams a single, standardised API to read balances and transactions from Grong Sparebank and 2,600+ other banks across the EU and UK. Authenticate once, and keep your bookkeeping, budgeting or treasury tools synced automatically.

How to connect Grong Sparebank

  1. Create an open-banking.io account and grab your API key.
  2. Call the endpoint listing supported institutions and select Grong Sparebank.
  3. Redirect the account holder to Grong Sparebank's own login to approve access.
  4. Receive the consent token and begin fetching account data straight away.

The whole flow takes minutes, and the account holder always confirms access inside their trusted banking environment.

What data you can access

  • Accounts — business and personal account details and identifiers
  • Balances — up-to-date cleared and available amounts
  • Transactions — dated, categorisable movement history for reconciliation

Grong Sparebank supports consent windows of up to 180 days, so you refresh authorisation twice a year rather than constantly. Both business and personal account types are covered. Note that no BIC is published for this institution, so use the open-banking.io institution identifier when connecting.

Privacy by design

our platform is zero-knowledge: data flows straight to your application and is never mined or resold. There are no eIDAS certificates to buy, renew or install — the certificate-free setup removes the heaviest compliance burden from PSD2 access, so a small team can go live as fast as an enterprise.

Pricing

One flat subscription of roughly EUR 3/month covers your Grong Sparebank connection along with the full 2,600+ bank network. No per-call surcharges, no setup fees.

Do I need my own bank licence to use this?

No. open-banking.io provides the regulated access layer, so you consume a clean API without holding your own PSD2 authorisation.

How often can I refresh Grong Sparebank data?

As often as your app needs within the active consent period. Once the 180-day window lapses, the account holder simply re-approves.

Can I connect both business and personal accounts?

Yes. Grong Sparebank exposes both account types, and the same API handles each identically.
