How this service works
Authorize one UK vendor payment-detail change using current supplier controls, an existing authorization reference and a fresh independent challenge. Use before updating a payee record. The result is expiring and single-use; raw bank data is not accepted.
Output
Returns a single-use, expiring authorization reference confirming that the proposed vendor payment-detail change is approved under the current supplier controls and challenge evidence. The result is time-limited and must be consumed immediately when updating the payee record; raw bank data is never returned.
Example use cases
Secure supplier bank account update
“Our finance team needs to change the payment details for UK supplier number 09876543 — current payee fingerprint is 'fp-CURR-9912', proposed is 'fp-NEW-4481', prior auth ref is 'VEND-AUTH-88', and we have a BANK_PROVIDER_CONFIRMATION reference 'BPCONF-2025-77' verified an hour ago, valid for the next 24 hours. Can you get the authorization so we can safely update the payee record?”
Fraud-check before payee record edit
“Before my accounts-payable system updates the bank details for Companies House number OC112233, I need a single-use authorization. Current fingerprint is 'fing-OLD-332', proposed is 'fing-NEW-881', existing authorization ref is 'AP-BIND-2025-55', and the challenge is a CUSTOMER_CONFIRMATION type with reference 'CUST-CONF-101', verified just now, expiring in 6 hours.”
Automated vendor onboarding payee change gate
“As part of our automated vendor onboarding pipeline, I need to authorize a payment-detail change for UK company 00445566 — old payee fingerprint 'payee-hash-AA1', new fingerprint 'payee-hash-BB2', prior authorization reference 'ONBOARD-AUTH-2025-9', with a PREVIOUSLY_VERIFIED_BINDING challenge reference 'PVB-REF-007' verified yesterday, valid until end of day today. Generate the expiring approval so the pipeline can proceed.”
Technical details
Endpoint
POSThttps://cdo-production.up.railway.app/v1/gb/vendors/authorize-payment-detail-changeWhen to prefer
Use this endpoint specifically when you need to authorize a change to an existing UK vendor's payment details before updating a payee record, and you already hold a prior authorization reference and a fresh independent challenge. It is the right choice when raw bank data must never be transmitted and the approval must be single-use and time-limited. Prefer it over generic authorization flows when UK Companies House company controls and payee fingerprinting are the required security model.
Side effects
- Challenge expired (valid_until in the past) — authorization rejected
- Prior authorization reference not found or already consumed — request fails
- Payee fingerprint mismatch with existing records — authorization denied
- Company number format invalid or not found at Companies House — validation error
- Idempotency key reuse with differing parameters — conflict error
- Challenge type not accepted given current supplier controls — rejected
- Authorization result already consumed (single-use exhausted) — cannot reuse
