What is Subscription Bill Payment?

The Subscription Bill Payment from JustSwitch lets product teams pay bbps utility data in real time through a single REST integration. Designed for the BBPS / Utilities lane, it removes manual checks, reduces drop-offs in onboarding funnels, and returns structured JSON that your risk engine, CRM, or core banking system can consume instantly.

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.

Payment rails include idempotency keys, webhook callbacks, and reconciliation IDs so finance teams can match ledger entries without spreadsheet gymnastics. BBPS integrations operate within the NPCI Bharat BillPay ecosystem.

Developers choose JustSwitch for Subscription Bill Payment 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 Subscription Bill Payment used for?

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

How do I integrate Subscription Bill Payment 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 Subscription Bill Payment 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.
