1 Best APIs for Merchant KYC Onboarding in Nigeria

SPay Business Solutions Ltd is a Nigerian payment technology company offering a streamlined payment gateway designed specifically for Nigerian businesses, SMEs, freelancers, and service providers who need to accept online payments without complex infrastructure. Operating under the tagline "Payment Simplified!", SPay focuses on making payment collection accessible to businesses of all sizes — from solo freelancers generating payment links to online stores integrating a full checkout API. **What SPay Does** SPay provides a payment processing platform with four core capabilities: online payment acceptance, virtual account creation, payment link generation, and subscription/recurring billing management. These services are accessible via a RESTful API documented through readme.io, as well as via the SPay merchant dashboard for non-technical users who need payment links without coding. **Payment Acceptance API** SPay's payment API allows merchants to initiate payment sessions, redirect customers to a hosted payment page or embed a checkout widget, and receive payment confirmation via webhooks. The API handles both card payments and bank transfer acceptance, giving merchants multiple collection channels in a single integration. Standard REST API conventions are followed, with responses in JSON format and test payment tools provided for developer integration testing. **Virtual Accounts via First Bank of Nigeria** One of SPay's distinguishing features is its integration with First Bank of Nigeria for virtual account issuance. Merchants can programmatically create unique Nigerian bank account numbers (virtual accounts) that are tied to a specific customer or transaction. When a customer makes a bank transfer to the virtual account, SPay detects the payment in real time and notifies the merchant via webhook — enabling seamless bank transfer payment collection without manual reconciliation. This is particularly valuable for Nigerian consumers who prefer bank transfers over card payments. **Payment Links** SPay allows merchants to generate shareable payment links from the dashboard or via API — links that customers can open in a browser to complete a payment. This makes SPay accessible to businesses without a website, allowing freelancers, event organizers, and service businesses to collect payments via WhatsApp, email, or social media with zero code required. **Subscription & Recurring Billing** For SaaS products, membership platforms, schools, and subscription boxes, SPay offers a recurring billing module that handles automated charge schedules on weekly, monthly, or annual cycles. Merchants set up subscription plans, customers authorize the recurring payment, and SPay manages the billing cycle, retry logic for failed payments, and subscription lifecycle events. **Authentication** SPay uses API key-based authentication. Merchants receive API credentials (public key and secret key) after completing the merchant onboarding and KYC process on the SPay dashboard. API keys are passed in request headers for all API calls. Test mode credentials are provided separately and can be used to test integrations without processing real transactions. **Merchant Onboarding & KYC** To go live on SPay, merchants must complete a KYC process that includes providing business registration details (CAC certificate), bank account information for settlement, and identity verification for directors. This is standard practice for all Nigerian payment gateways operating under CBN regulatory requirements. Developers and businesses can test the API with test credentials before completing KYC — making it easy to build and validate integrations before going live. **Sandbox / Test Environment** SPay provides test payment capabilities for developers to simulate transactions and validate integrations without real money movement. The documentation on readme.io includes response codes and test scenarios. **Pricing** SPay uses a commission-based pricing model — merchants pay a percentage of each transaction processed. Specific fee percentages are not publicly listed on the website; merchants receive a pricing schedule upon completing merchant onboarding. No publicly advertised monthly subscription fee has been found. **Nigeria Context & Regulatory Standing** SPay is a Nigeria-focused payment company serving Nigerian merchants under CBN payment regulations. Banking partner arrangements, including the First Bank virtual account integration, operate within Nigeria's licensed payment infrastructure. SPay is suitable for Nigerian businesses that want a simpler, more focused payment solution compared to the complexity of larger platforms like Paystack or Flutterwave — particularly for businesses that primarily need virtual accounts and payment links rather than a full payments ecosystem. **Challenges for Nigerian Developers** SPay is a smaller gateway with fewer integrations and ecosystem tools compared to market leaders like Paystack or Flutterwave. The public documentation, while functional, is not as comprehensive or community-supported as larger platforms. Bulk payout/transfer capabilities, USSD payments, and POS integration are not available in the current product offering. International card acceptance (non-NGN) is also not documented as a supported feature. **Frequently Asked Questions** Q: Does SPay support USSD payments? A: No. SPay currently supports card payments and bank transfers via virtual accounts — not USSD. Q: Can I use SPay without a registered business (CAC)? A: A CAC-registered business is required for production access. Developers can test with sandbox credentials before completing KYC. Q: How are virtual accounts created through SPay? A: Virtual accounts are issued in partnership with First Bank of Nigeria via the SPay API — each account receives a unique Nigerian bank account number that customers can transfer to. Q: Does SPay support international payments? A: SPay is primarily focused on NGN payments for Nigerian customers. International card acceptance is not a documented feature. Q: Is there a recurring billing feature? A: Yes — SPay includes a subscription management module for automated recurring billing on daily, weekly, monthly, or annual schedules.
