GSubz API

Communications · Payments

GSubz is a Nigerian VTU (Virtual Top-Up) platform and API provider that lets developers integrate instant airtime recharge, mobile data bundle purchases, cable TV subscription payments (DStv, GOtv), and electricity bill payments into their own websites and applications. It supports the major Nigerian mobile networks - MTN, Glo, Airtel, and 9mobile - alongside utility billers, positioning itself as a reseller-friendly backend for VTU and bill payment businesses.

Best For

Nigerian developers and small resellers building VTU storefronts or bots that need airtime, data, cable TV, and electricity payment in one simple API

Pricing

Documentation is thin on operational details - no published rate limits, no IP whitelisting guidance, and no webhook/callback support, so integrators must poll the verify endpoint for transaction status. Pricing is commission/discount-based (up to 7% off airtime, up to 5% across networks) rather than a flat API fee, so cost scales with transaction volume and network. Sandbox testing is supported via separate testpay/testverfy endpoints before going live.
