1 Best APIs for Card Payments (3DS + 2FA) in Nigeria

RexPay is a Nigerian payment gateway solution developed by Global Accelerex Limited, a leading electronic payment and business management solutions company operating in Nigeria and West Africa. Global Accelerex holds both a CBN Payment Solution Service Provider (PSSP) certification and a CBN Payment Terminal Service Provider (PTSP) certification — a dual certification that covers online payment processing and POS terminal management respectively. This makes Global Accelerex one of the few Nigerian companies with both licenses, giving RexPay institutional-grade credibility as a payment infrastructure partner. The RexPay API is RESTful with JSON payloads. Documentation is available at rexpay-docs.globalaccelerex.com. Authentication uses an API Key obtained from the RexPay merchant dashboard. Developers initialize payment transactions by sending a POST request with the amount and transaction reference, then display the RexPay checkout to the customer. RexPay supports three payment channels in Nigeria: card payments (Visa, Mastercard, Verve with 3D Secure / 2FA verification), internet banking transfers (bank-to-bank transfers via the customer's internet banking), and USSD (for customers on basic mobile phones without internet access). This covers the three primary payment behaviors of Nigerian consumers: card users, mobile banking users, and USSD users. For WordPress-based e-commerce stores, RexPay provides a WooCommerce plugin that can be installed directly from the WordPress plugin directory. This no-code integration allows Nigerian merchants to add RexPay checkout without writing a single line of code — simply install, configure the API key from the dashboard, and payments start flowing. Pricing for RexPay starts from $0 per month, indicating no mandatory platform fee. Transaction fees are commission-based and negotiated during merchant onboarding. The exact percentage rates are not published publicly but are competitive with other Nigerian gateways. The $0/month model makes RexPay accessible to small businesses and startups that cannot commit to monthly subscription fees. The sandbox environment allows full testing of all payment channels. Moving to live requires completing the Global Accelerex KYC process, which involves submitting CAC documents, director BVN, and business bank account information. From a compliance standpoint, Global Accelerex is CBN-certified under both the PSSP and PTSP frameworks, meaning that all payment transactions processed through RexPay meet CBN regulatory standards. PCI-DSS compliance ensures card data is handled and stored securely. RexPay is a focused Nigeria-only payment gateway — it does not currently support international payment corridors or other African countries. This is a trade-off that simplifies compliance but limits its usefulness for businesses with pan-African payment needs. Known challenges: RexPay's documentation and developer community are smaller than Paystack or Flutterwave. Advanced features like split payments, virtual accounts, and recurring billing are not currently supported. International card acceptance (for non-Nigerian Visa/Mastercard holders) may have limitations. Frequently Asked Questions: What is Global Accelerex? Global Accelerex is the parent company of RexPay.
