What is Mobile to VPA?

Mobile number se linked UPI VPA dhundhta hai.

Every request is authenticated with API keys, logged for audit, and routed through regulated partner rails where required. Responses follow a consistent `{ ok, data, message }` envelope so you can ship once and reuse the same error-handling patterns across all JustSwitch endpoints.

Whether you run a lending app, payment aggregator, or enterprise ERP, Mobile to VPA scales horizontally with rate limits tuned for burst traffic during campaigns. Bank and PAN validation services are offered through regulated partners and authorised aggregators in the NPCI ecosystem.

Developers choose JustSwitch for Mobile to VPA because we aggregate multiple upstream providers behind one contract, one wallet settlement, and one support desk — so you launch faster while your compliance team retains full audit visibility through dashboard logs and exportable reports.

Frequently asked questions

What is Mobile to VPA used for?

It automates Bank / Penny Drop workflows so your application can verify or transact in real time without building direct integrations with multiple upstream providers.

How do I integrate Mobile to VPA in my app?

Sign up on JustSwitch, obtain sandbox API keys, call the REST endpoint with JSON body, handle the unified response envelope, then switch to production keys after UAT sign-off.

How do I authenticate requests?

Use Bearer API keys from the JustSwitch dashboard. Sandbox and production keys are separated; rotate keys anytime without downtime.

Is there a sandbox for testing?

Yes — every API supports sandbox mode with simulated responses so engineering, QA, and compliance can sign off before go-live.

What about webhooks and async status?

Long-running operations (payments, recharge, some KYC steps) emit webhooks to your HTTPS endpoint with signed payloads for replay protection.

Is Mobile to VPA compliant for regulated use in India?

JustSwitch routes requests through authorised AUA/KUA, NPCI, MCA and partner networks. Your legal team should map consent, data retention and licence obligations to your use case.
