Frequently asked questions

Can I use this for my own accounts?

Yes. Sign up as an individual, connect your own accounts by approving access at your bank, and create an API key. There is no AISP registration to apply for, no company to form and no sales call.

Do I need to be an AISP or registered with the FCA?

No. Reading account data on someone’s behalf requires FCA authorisation as an AISP, and the provider BankSync connects through, Salt Edge, holds it. You approve access at your bank and read your own data back through your key.

How long does my consent last, and how do I renew it?

UK open banking access lasts 180 days. When it ends, reconnect the bank from the app and approve again at your bank. You can withdraw access at any time from your bank or from BankSync.

What data can I read, and how far back?

Transactions and balances. The first sync reaches back up to 60 days; from then on BankSync keeps adding new transactions, so your history grows for as long as the connection stays active.

What is not available in the UK?

Investment holdings, investment trades and loan details: the UK connection returns transactions and balances only. Payments are never available; the API is read-only.

Is the API read-only?

Yes. The connection your bank grants is read-only: BankSync can read account data, and it cannot move money, make payments or change anything at your bank. Your API key reads the same data, scoped to the permissions you give it.

How is this different from screen-scraping?

You never share your banking password. UK Open Banking sends you to your own bank’s app or website to approve access, and the bank issues a revocable token. Screen-scrapers sign in as you with your stored credentials.

How much does API access cost?

API access starts on Standard at US$7/mo: up to 5 bank connections, 10 API requests a minute and the MCP server. Professional and Business raise the limits. Every plan starts with a 14-day free trial; prices are in USD.
