Pay claims via push-to-card disbursements using Visa Direct

Verified steps

1. Register on the Visa Developer Center at developer.visa.com and obtain sandbox credentials; note that production access requires sponsorship by a licensed Visa acquirer — engage a payment processor or bank partner for production enablement.
2. Authenticate API calls using mutual TLS (mTLS) with your Visa-issued certificate plus an API key header; include X-CLIENT-TRANSACTION-ID with a unique value per request for idempotency.
3. Collect the recipient's 16-digit Visa card number (PAN), recipient name, and billing address; validate that the card is eligible for Original Credit Transactions (OCT) by calling the CardAcceptance endpoint if available in your implementation.
4. POST to the Funds Transfer API endpoint (consult developer.visa.com/capabilities/visa_direct for the current endpoint path) with an OCT payload: recipientPrimaryAccountNumber, amount, currency, businessApplicationId (set to 'BI' for insurance claims), and senderAccountNumber.
5. Parse the response for transactionIdentifier and actionCode; a '00' action code indicates approval; store the Visa transaction ID against the claim record for reconciliation.
6. For failed or declined OCTs, implement a fallback disbursement method (ACH, check) and notify the claimant; Visa Direct does not guarantee same-day settlement on all card issuers — communicate expected fund availability as 'typically within 30 minutes but up to 1 business day'.
