I want to replace the monthly back-and-forth of bank statements with a seamless portal that connects to all major UK banks through open-banking APIs. When I send a client a unique sign-up link, they should authenticate once with their bank, then log in to our portal with a simple email-and-password account. From my side I need to choose any past date range and immediately download that client’s transactions as a clean CSV file. Key requirements • Coverage: all major UK banks through a single aggregated open-banking connection (TrueLayer, Yapily, Plaid, or a comparable FCA-regulated provider). • Data format: CSV only, with column headers exactly mirroring the raw API fields so we can drop the file straight into Excel or our internal tools. • Ninety-day rule: the open-banking consent must auto-renew in the background so the client never has to re-authorise. • Admin dashboard: search by client, pick a custom date span, view a quick on-screen summary, then one-click CSV export. • Security & compliance: GDPR-ready data storage, encrypted at rest and in transit, full audit trail, and sensible rate-limiting on API calls. Acceptance criteria 1. A demo account shows live data pulled from at least two production UK banks. 2. CSV download reproduces every field returned by the API for the selected period without data loss or reordering. 3. After 90 days the connection still delivers fresh data without client action, verified through a scheduled job or webhook re-authorisation. 4. Pen-test report or similar evidence confirms OWASP top-10 issues are addressed. If you have shipped a similar open-banking product, especially with TrueLayer or Plaid, I would love to see it. Let’s discuss your preferred stack and timeline so we can move this in-house quickly. Similar product as Steem Connect but for our inhouse team only
