2 Best APIs for payment infrastructure in Nigeria

Sudo Africa is an open API platform that simplifies payment card issuance and virtual account creation across Africa. The platform handles compliance and bank relationships, allowing developers to build, launch, and grow financial services in minutes rather than months. Founded with a focus on African markets, Sudo Africa abstracts complexity while providing powerful financial infrastructure. Developers integrate through REST APIs to access three core products: Cards (for issuing physical and virtual payment cards with spending controls and real-time authorization), Accounts (for creating local and international virtual bank accounts), and Cloud Card (additional card management capabilities). The platform emphasizes that "Sudo owns the heavy lifting of compliance and bank relationships so you can build, launch, and grow faster." Authentication uses standard API key Bearer tokens generated from the developer dashboard. Developers gain access to comprehensive documentation at docs.sudo.africa, a GitHub repository with code examples, and a developer Slack community for support. Test mode is fully featured and functional before KYC approval, enabling rapid prototyping. The platform supports spending controls, real-time authorization, and complete card lifecycle management including card creation, activation, and transaction monitoring. For Nigerian developers, Sudo Africa eliminates traditional friction in financial infrastructure — no need to negotiate directly with banks or build compliance from scratch. The platform has integrated partnerships with banking infrastructure providers across Africa, ensuring regulatory compliance and seamless fund settlement. Key technical features include granular spending controls (set limits by merchant, amount, time window, or card-specific rules), real-time authorization with instant response times, webhook support for transaction events, and multi-currency account support. The platform is ideal for fintechs building employee cards, customer prepaid solutions, marketplace payment infrastructure, or neobank services. Getting started requires signing up at app.sudo.africa/signup, accessing the developer dashboard for API keys, and reviewing documentation at docs.sudo.africa. Production access requires standard business documentation and KYC verification. Sudo Africa handles PCI-DSS compliance, reducing the compliance burden on developers.

Wireless is a financial technology platform specializing in payment card issuance and USSD solutions tailored for African markets. The company provides two primary services: Card Issuing API for programmatic creation and management of physical and virtual payment cards, and USSD Solutions that enable mobile transactions without internet connectivity — critical infrastructure across African markets where mobile money adoption is high but data penetration remains limited. The platform is designed specifically for African regions where traditional payment infrastructure gaps exist. The Card Issuing API allows developers to create, manage, and distribute cards at scale, with support for spending controls and authorization management. USSD solutions enable frictionless payment collection through simple menu-based interactions on basic mobile phones, addressing the digital divide in payment adoption across Africa. Developers integrate through REST APIs with standard authentication mechanisms. The platform emphasizes reliability and local market focus, providing services tailored to African regulatory requirements and user behaviors. Support for USSD is particularly valuable in markets like Nigeria where USSD-based payment adoption exceeds internet-based alternatives in some segments. The platform provides infrastructure for fintech platforms, neobanks, and financial service providers building in Africa. For Nigerian developers, Wireless eliminates the need to build both card infrastructure and USSD support separately — both are available through a unified platform. The USSD offering is especially relevant given Nigeria's high USSD payment adoption rates and the importance of providing payment methods that work across all phone types. Card issuance features include virtual and physical card support, spending controls, real-time authorization, and card lifecycle management. The platform handles compliance with local regulations and provides documentation for integration. Test mode allows developers to validate their integration before going live. Production access requires standard business documentation and KYC verification aligned with Nigerian banking regulations.
