PayCIS is an online payroll application used by UK businesses to prepare and approve bulk payments to workers. Website: https://paycis.co.uk
The payroll logic, approvals, logging, and manual payment fallback are already built. We now want to add automated payments for users with a Starling Business bank account.
⸻
What we need
A developer to integrate Starling Bank’s native Business API so approved payroll payments can be executed directly from the user’s own Starling account, with automatic success/failure updates.
This is: • ✔ Bank-native API • ❌ Not Open Banking • ❌ Not file uploads • ❌ No client money handling
⸻
Scope
1. Starling account connection • Implement Starling OAuth (connect / disconnect) • Secure token storage and refresh • Reuse existing OAuth patterns where possible
2. Payroll payment execution • Use Starling Business Payments API • One API call per payment (10–50 per run) • Store paymentUid and prevent duplicates
3. Payment status updates • Handle Starling webhooks • Mark payments as paid or failed • Log outcomes and failure reasons
4. Error handling • Insufficient funds, invalid details, revoked tokens • Retry or fall back to manual payment
Please include: • Relevant bank / payments API experience • Confirmation this is Starling Business API (not Open Banking) • Estimated timeline and FIXED cost. Note that we do not accept estimated or open ended costs, only a FIXED price. Please confirm this in your response.
