3 Best APIs for PSSP in Nigeria

RoutePay Fintech Limited is a Nigerian payment technology company that received its Full Operating Licence from the Central Bank of Nigeria (CBN) as a Payment Solution Service Provider (PSSP) on January 12, 2023 — making it one of the newer entrants to Nigeria's regulated payment gateway space. The company is also certified by the Nigerian Communications Commission (NCC) for Value-Added Services, giving it a dual regulatory standing that covers both financial payments and telecoms-adjacent services like airtime and data transactions. Headquartered in Victoria Island, Lagos (Africa Re House, Plot 1679 Karimu Kotun Street), RoutePay operates under the leadership of CEO Abayomi Olomu and Group Managing Director Femi Adeoti (former MD of Inlaks). The company is registered as RoutePay Fintech Limited (RC 1872221) and uniquely owns a licensed microfinance bank subsidiary — Routelink Microfinance Bank Limited (RC 8836108) — enabling it to offer embedded merchant credit alongside payment processing, a rare combination in Nigeria's payment gateway landscape. **Omnichannel Payment Infrastructure** RoutePay is built as a truly omnichannel payment platform — not just an online gateway, but a complete payments infrastructure that covers every channel Nigerian consumers and businesses transact on: - **Web**: Browser-based checkout integration for e-commerce and business websites - **Mobile**: SDK and API integration for iOS and Android apps - **POS**: Physical terminal support for retail and hospitality merchants - **ATM**: ATM payment routing for cash-based and card-based transactions - **USSD**: Short code-based payment acceptance for feature phone users and financial inclusion scenarios This breadth of channels makes RoutePay particularly valuable for businesses that operate across both digital and physical environments, or for government institutions that need to serve citizens regardless of smartphone availability. **Core Payment Features** RoutePay supports card payments (debit and credit — Visa, Mastercard, Verve), direct bank transfers, USSD codes, QR code payments, and payment link generation. The payment link feature is specifically designed for social media sellers and informal businesses that take orders via WhatsApp, Instagram, or phone — allowing them to collect payments without a dedicated website. **Bill Payments API** Beyond payment acceptance, RoutePay provides a bill payments module covering: airtime top-up for all Nigerian mobile networks (MTN, Airtel, Glo, 9mobile), mobile data purchases, DSTV/GOtv/Startimes cable TV subscription renewals, and PHCN/DISCOs electricity prepaid token purchases. This module enables developers to build super-apps and lifestyle platforms with embedded utility payment capabilities. **Merchant Micro-loans via Routelink MFB** One of RoutePay's most distinctive features is its integration with Routelink Microfinance Bank. Merchants who process payments through RoutePay become eligible for micro-loans whose terms are informed by their transaction history and payment volumes on the platform. This provides Nigerian SMEs with access to working capital financing without the collateral requirements and bureaucratic overhead of traditional bank loans — the loan eligibility is earned through demonstrated business activity rather than pre-existing credit history. **Government & Institutional Payments** RoutePay explicitly targets government and public sector clients, enabling tax collection, licensing fee payment, regulatory fee submission, and institutional disbursements. The USSD channel support is particularly valuable here — it allows citizens in areas with limited internet access to make payments to government agencies using any mobile phone. **Security Architecture** RoutePay implements bank-grade AES encryption across all transactions, combined with two-factor authentication (2FA) for account access and a real-time fraud monitoring system. Auto-reversal protocols ensure that failed transactions are automatically reversed without manual intervention. The platform also offers account freeze capability for security incidents. **Tiered KYC System** RoutePay implements a Tier 1 / Tier 2 / Tier 3 KYC model for individual users, consistent with CBN's tiered KYC framework for digital financial services. Higher tiers unlock larger transaction limits — Tier 1 requires minimal information (BVN linkage), while Tier 2 and Tier 3 require progressively more documentation (government ID, address proof, enhanced verification). This tiered approach enables financial inclusion while managing regulatory compliance. **Authentication & API Access** RoutePay provides API access for developers through its developer portal. API credentials are issued after completing merchant KYC/onboarding. The API follows REST conventions with JSON request/response formats. For developer documentation and API access, developers can visit routepay.com/developers or contact sales@routepay.com. **Pricing** RoutePay charges no monthly maintenance fees. Transaction fees are per-transaction at industry-standard rates, with full transparency on charges — no hidden fees. Specific fee percentages are provided during merchant onboarding rather than published on the website. Micro-loan terms are governed separately by Routelink MFB's lending policies. **Challenges for Nigerian Developers** RoutePay's public developer documentation is less detailed than market leaders like Paystack or Flutterwave, and specific API specifications, authentication details, and rate limits are not publicly documented — requiring developer outreach to access. Recurring/subscription billing is not a documented product feature. For businesses that primarily need a straightforward online payment gateway with comprehensive public documentation, larger platforms may offer a smoother developer experience. **Frequently Asked Questions** Q: Is RoutePay licensed by the CBN? A: Yes. RoutePay holds a CBN PSSP Full Operating Licence granted January 12, 2023. Q: Does RoutePay support USSD payments? A: Yes — USSD is one of RoutePay's five supported payment channels, enabling payments from any Nigerian mobile phone. Q: What makes RoutePay unique compared to Paystack or Flutterwave? A: RoutePay's key differentiators are its omnichannel coverage (including ATM and USSD), its institutional/government payment capabilities, and its embedded micro-loan product through Routelink MFB. Q: Can my business get a loan through RoutePay? A: Merchants processing payments on RoutePay become eligible for micro-loans from Routelink MFB — eligibility and terms are based on transaction volume and history on the platform. Q: Does RoutePay have a sandbox for testing? A: Contact RoutePay's developer team at routepay.com/developers or sales@routepay.com for sandbox access details.

Unlimit (formerly known as CardPay, then Unlimint) is a global financial technology company with over 15 years of experience in international payment infrastructure. Headquartered across multiple regional offices and operating in 200+ locations worldwide, Unlimit provides payment processing, multi-currency business accounts, Banking-as-a-Service (BaaS), and cryptocurrency on/off-ramp services to merchants, platforms, and financial institutions globally. Africa — specifically Nigeria, Kenya, and Tanzania — is explicitly listed as a supported region in Unlimit's global coverage. The company has undergone a notable branding evolution: originally known as CardPay, it rebranded to Unlimint, and subsequently to Unlimit (the current brand). Its core payment processing technology remains under the CardPay API specification (version 2.70), which continues to be used by integrators and is documented at integration.unlimit.com. The legacy GitHub repositories can be found under the "cardpay" organization on GitHub, reflecting the original brand. **Core Products** 1. **Payment Gateway** — Unlimit's flagship product: accepting card payments, local payment methods, and alternative payment methods (APMs) from customers in 200+ locations. The gateway supports over 1,000 payment methods — an exceptionally broad catalog that includes regional methods specific to Africa, Latin America, Asia-Pacific, Europe, and India. For Nigerian merchants, this means access to local Nigerian payment methods alongside international Visa, Mastercard, and Amex cards. The gateway supports both Payment Page Mode (where customers enter card details on Unlimit's hosted checkout page) and Gateway Mode (server-to-server, where the merchant's own application handles card data collection under PCI DSS compliance). 2. **Unlimit Accounts** — Multi-currency business accounts that allow businesses to hold, send, and receive funds in 30+ currencies. These accounts come with integrated card issuance for business spending and are accessible programmatically via API. For Nigerian businesses operating internationally, this provides a way to maintain USD, EUR, and GBP balances without going through traditional Nigerian commercial bank FX channels. 3. **Banking as a Service (BaaS)** — A white-label financial infrastructure layer that enables fintechs and non-bank businesses to offer card issuing, payment processing, and banking features under their own brand. The BaaS offering connects to SEPA (Euro transfers), SWIFT (international transfers), and BACS (UK transfers) payment rails. 4. **Unlimit Crypto** — An on/off-ramp service for crypto-native platforms: DeFi protocols, GameFi platforms, NFT marketplaces, and crypto exchanges can accept fiat currency from users and pay out in cryptocurrency (or vice versa) using Unlimit's crypto conversion infrastructure. **API Architecture & Authentication** The Unlimit (CardPay) API uses terminal-based credentials for authentication. Each merchant is assigned a Terminal Code and Password, which are used to generate SHA-512 HMAC signatures for request authentication — providing tamper-evident server-to-server authentication. OAuth 2.0 is used for certain API flows. The API has two primary modes: Payment Page Mode uses redirect-based flows, while Gateway Mode enables direct card processing on the merchant's own checkout page (requiring PCI DSS certification). The API is documented at integration.unlimit.com and legacy references appear on integration.unlimint.com (which redirects). **Sandbox Environment** Unlimit provides a sandbox environment for integration testing. Developers can simulate payments, test 3D Secure flows, and validate webhook integrations without processing real transactions. Sandbox credentials are separate from production credentials. **3D Secure & Fraud Prevention** Unlimit supports 3D Secure (3DS1 and 3DS2) for card authentication. In 3DS2 flows, Unlimit can collect additional customer authentication data either from the merchant's side or through an intermediate authentication page. This reduces chargebacks and strengthens payment security — particularly important for high-risk verticals like gaming, travel, and international e-commerce. **Recurring & Subscription Billing** Unlimit's gateway supports recurring payment schedules, making it suitable for subscription businesses that need to charge customers on weekly, monthly, or annual cycles without requiring manual card entry for each period. **Africa & Nigeria-Specific Context** Nigeria is one of three African markets explicitly listed in Unlimit's geographic coverage (alongside Kenya and Tanzania). For Nigerian merchants, this means Unlimit supports local Nigerian payment methods in addition to international cards. However, Unlimit is not a Nigerian-native payment provider — it is a global gateway that supports Nigeria as part of its multi-regional infrastructure. Businesses primarily serving the Nigerian domestic market may find Nigerian-native gateways (Paystack, Flutterwave) more deeply integrated with local payment methods and better suited to local developer support. Unlimit's strongest value proposition for Nigerian-connected businesses is multi-currency acceptance and serving international customer bases that include Nigeria. **Pricing** Unlimit does not publicly list pricing. Commercial terms are negotiated on a per-merchant basis depending on transaction volume, payment methods, geographic coverage, and vertical (gaming, travel, e-commerce, etc.). Merchants must contact Unlimit's sales team for pricing. This is typical for enterprise-grade global payment gateways. **Compliance & Licensing** Unlimit operates under financial services licenses in multiple jurisdictions. The company implements KYC and AML processes for merchant onboarding. Specific license details for Nigerian operations are not publicly disclosed — Unlimit operates as an international payment processor interfacing with Nigerian payment infrastructure rather than holding a direct CBN license. **Frequently Asked Questions** Q: Is Unlimit the same as CardPay? A: Yes. Unlimit was previously known as CardPay, then rebranded to Unlimint, and now operates as Unlimit. The core API documentation remains under the CardPay/CardPay API versioning. Q: Does Unlimit support Nigerian payment methods? A: Nigeria is explicitly listed as a supported market. Unlimit supports local Nigerian payment methods alongside international cards. Q: What is the difference between Payment Page Mode and Gateway Mode? A: Payment Page Mode redirects customers to Unlimit's hosted checkout for card entry. Gateway Mode processes card data directly on the merchant's site (requires PCI DSS compliance). Q: Is self-serve onboarding available? A: No. Merchant onboarding requires contacting Unlimit sales for custom pricing and a commercial agreement. Q: Does Unlimit support crypto payments? A: Yes. Unlimit Crypto provides on/off-ramp services enabling fiat-to-crypto and crypto-to-fiat conversions for DeFi, GameFi, and NFT platforms.

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. It is one of Nigeria's oldest e-payment companies, providing POS terminals, payment switches, and software solutions to Nigerian banks and enterprises since the early 2000s. Does RexPay work with WooCommerce? Yes — a WooCommerce plugin is available that allows Nigerian WordPress store owners to accept payments through RexPay without any coding. Can I use RexPay for B2B corporate payments? Yes — RexPay supports internet banking transfers, which is the preferred payment method for Nigerian corporate clients making large business-to-business payments.
