Frequently asked questions
What is UPI?
India’s Unified Payments Interface — the world’s largest real-time consumer payment network.
How fast is UPI?
Real-time. Actual settlement time is disclosed pre-approval and confirmed by signed webhook once the beneficiary bank acknowledges the credit.
Which countries can I reach through UPI?
IN. Availability is beneficiary-bank-dependent; the router falls back to wire if the beneficiary bank is not on UPI.
What currencies are supported on UPI?
INR is the primary settlement currency for UPI. Multi-currency corridors are supported where the rail permits.
What limits apply on UPI?
Rail-specific ceilings apply; the platform surfaces them pre-approval. Higher-value transactions are automatically routed to wire.
Is UPI available 24/7?
Real-time rails (including UPI) operate around the clock. Batch and wire rails follow the local banking window.
How do I integrate UPI?
You don’t. KeyBS Pay abstracts rail selection: submit a payout to POST /v1/payouts and the router picks the fastest eligible rail. Use "method": "auto" (default) or force a specific method where policy requires.
Is UPI regulated?
Yes. KeyBS Pay routes UPI payouts only through partners licensed for the destination corridor.
Can I get a UPI settlement report?
Yes. Per-rail, per-corridor reconciliation reports are available in the dashboard and via API export.
What happens if a UPI payout fails?
Failed payouts return a signed webhook event with a machine-readable reason code. Funds remain in the source ledger and can be re-routed or refunded.
How is pricing set for UPI?
Quote-based, disclosed in full pre-approval. No undisclosed intermediary-bank deductions on eligible local rails.
Can I use UPI for consumer payouts?
Yes, where the beneficiary and route policy permit consumer flows. Stablecoin routes are business-only.
Are there cutoffs on UPI?
Real-time rails have no cutoffs. Batch and wire rails follow local banking-day windows; cutoffs are shown at quote time.
Does UPI support idempotent retries?
Yes. Every KeyBS Pay payout carries an Idempotency-Key so retries after transient errors are safe.
Which industries use UPI most?
Marketplaces, cross-border trade, workforce and NGO programs are the largest users of UPI on the KeyBS Pay platform.
