The VTU API for Developers
Integrate airtime, data, bills, e-pins and more into your own app or platform with Bigisub's well-documented, enterprise-grade VTU API.
What You Can Automate
The Bigisub VTU API gives you programmatic access to every service on the platform. You can automate airtime top-ups across all Nigerian networks (MTN, Glo, Airtel, 9mobile), purchase data bundles at wholesale rates, pay electricity bills for all distribution companies, subscribe to cable TV (DStv, GOtv, Startimes), generate result checker e-pins for WAEC, NECO and NABTEB, and send bulk SMS.
Every endpoint returns clear JSON responses with transaction status, reference numbers and balance updates. Whether you are building a fintech app, a reseller platform, a customer rewards system or an internal operations tool, the API handles the complexity so you can focus on your product.
Reliability and Uptime
Bigisub maintains a 99.9% uptime SLA backed by redundant infrastructure and automatic failover. Nigerians nationwide depend on the platform daily, and the API serves the same production infrastructure that powers the Bigisub web and mobile apps. You get the same speed, the same reliability and the same transaction success rates.
All API responses include detailed error codes and messages, making it straightforward to handle edge cases in your integration. Webhook support is available for asynchronous transaction status updates, so your system stays in sync without polling.

Illustrative, to show how a percentage-based funding fee scales with the amount - a fee that is forgettable on a small top-up is not forgettable at reseller volume. Funding fees differ by platform. Applies to transfers into your Bigisub permanent account number, which is issued free once your account is verified. Verification is free.
