We run a web application that prepares bulk payments (multiple recipients, amounts, references). That part is already built.
We need a developer to integrate Starling Business Bank’s native API so users with a Starling Business account can execute those payments directly from their own bank account.
This is: • ✔ Bank-native API integration • ❌ Not Open Banking • ❌ Not file uploads • ❌ Not handling client money
⸻
What needs to be built
1) Connect Starling Business Account • Add a “Connect Starling Business Account” button. • Implement Starling OAuth 2.0 authorisation. • Store access/refresh tokens, account UID and category UID securely. • Allow users to disconnect/revoke access.
⸻
2) Execute Bulk Payments
When a user approves a payment run in our system: • Use the Starling Business Payments API to create payments. • One API call per payment (looped execution). • Typical runs are 10–50 payments. • Capture and store the paymentUid for each payment. • Implement idempotency to prevent duplicates.
⸻
3) Payment Status Updates • Implement Starling webhooks for payment events. • Update each payment as paid / failed automatically. • Record failure reasons where available. • Write events to our existing activity log.
⸻
4) Error Handling • Handle token expiry/revocation. • Handle insufficient funds and invalid bank details. • Allow retry of failed payments. • Clean fallback to manual payment if needed.
