Is Westpac NZ supported?

Yes. Westpac New Zealand connects through Akahu, the New Zealand open banking platform, so you can link your accounts and start syncing in minutes.

How often does Westpac NZ sync to the Redbark API?

API requests proxy live from Westpac NZ at call time, and webhooks fire when new data reaches Redbark, within a few hours of a transaction posting.

Is my Westpac NZ connection read-only?

Yes. Akahu connections are read-only. Redbark can read transactions and balances, and can never move money or change your Westpac NZ accounts.

Does Redbark store my Westpac NZ data?

No. Redbark uses a pass-through architecture: your Westpac NZ transactions are proxied live to the Redbark API. We store consent records, encrypted tokens and minimal account metadata, never transaction amounts, descriptions or balances.

Is Redbark independently security tested?

Yes. Redbark was penetration tested in July 2026 by Project Black, a CREST-accredited Australian security firm, covering the web app, REST API, MCP server and admin console. The test returned zero critical and zero high-risk findings, and every finding raised was remediated and confirmed closed on retest.

How fresh is the Westpac NZ data from the API?

Requests proxy live from Westpac NZ via Akahu open banking at call time. Webhooks fire when new Westpac NZ data reaches Redbark, within a few hours of a transaction posting at your bank.

How are webhooks secured?

Every webhook payload is signed with an HMAC signature you verify against your signing secret, so you can confirm it genuinely came from Redbark.
