2 Best APIs for Card Management in Nigeria

Wireless Card Issuing and USSD API is an African fintech infrastructure platform that combines card issuance capabilities with USSD payment processing, providing two distinct but complementary payment channels through a single API integration. By offering both card-based payments for smartphone and internet users and USSD-based payments for feature phone and low-connectivity users, Wireless enables Nigerian and African platforms to maximize their payment acceptance coverage across the full spectrum of device and connectivity capability in the market. USSD (Unstructured Supplementary Service Data) is a GSM protocol that works on every mobile phone — from basic feature phones to modern smartphones — by dialing a short code that initiates a menu-driven session with a backend system. USSD requires no internet connection, no data plan, no smartphone, and no app installation. The payment session is conducted entirely through the familiar dial-pad interface that every mobile phone user already knows how to use. In a country like Nigeria where smartphone penetration reaches approximately 50 percent of mobile users, USSD-based payments provide critical market reach into the 50 percent of mobile users on feature phones and the substantial portion of smartphone owners who are on very limited data plans or in areas with poor internet connectivity. The Wireless USSD API provides a programmatic backend for USSD payment flows, connecting the carrier-delivered USSD session to the merchant's payment system. When a customer dials the merchant's USSD short code, the session is routed through Wireless's infrastructure to the merchant's API endpoint, which delivers menu prompts and processes customer inputs to complete the payment transaction. The merchant's API receives structured session data, can respond with text menus, and receives notification of successful payment completion. Card issuance through Wireless allows partner platforms to issue physical and virtual payment cards to their customers, extending the card infrastructure alongside the USSD capabilities. The combination serves different user segments: USSD for the feature phone and low-bandwidth segment, cards for internet-connected and smartphone users. A platform using Wireless can serve both groups from a single API relationship rather than integrating separate USSD and card infrastructure providers. Low-bandwidth optimization in Wireless's platform design reflects the reality that much of Nigeria's mobile internet infrastructure delivers variable data speeds. Payment flows and API responses are designed to function reliably even on 2G EDGE connections, which are still prevalent in rural areas and can appear in urban areas during network congestion. This optimization is not just a technical detail — it directly affects whether customers in rural Nigerian states and smaller towns can successfully complete transactions or are excluded from digital payment access. Spending controls on Wireless-issued cards allow partner platforms to configure transaction limits, merchant category restrictions, and per-day or per-period spending caps. For fintech platforms issuing expense cards or input finance cards with use restrictions, these controls ensure that issued cards are used within the intended scope. A cooperative issuing cards for agricultural input purchases can restrict card spending to approved input supplier merchant categories, preventing misuse of financed funds. Real-time authorization events from card transactions are delivered via webhooks to the partner platform, enabling immediate transaction visibility, fraud monitoring, and customer notification. For platforms operating at scale, real-time transaction events are essential for maintaining accurate account balances, detecting suspicious patterns, and delivering the instant transaction notifications that customers expect from modern fintech products. The dual-channel payment architecture of Wireless — covering both USSD for basic connectivity and cards for internet connectivity — reflects a practical response to Nigeria's heterogeneous digital infrastructure reality. Platforms that deploy only card or only online payment channels systematically exclude the portions of their potential market that don't have internet access or smartphone capability. Wireless's combined infrastructure removes this trade-off, enabling payment acceptance across the full user base a Nigerian platform serves.

Allawee Card Issuance API is a Nigerian Banking-as-a-Service platform that enables fintech companies, microfinance institutions, and digital platforms to issue physical and virtual payment cards, create bank accounts, process transfers, and perform credit decisioning through a single API integration. Allawee provides the regulated infrastructure for card issuance and banking operations, allowing partner platforms to offer branded financial products without obtaining independent banking or card scheme licenses. Card issuance is the foundational capability of the Allawee platform. Partner applications can issue Mastercard or Verve physical cards linked to customer accounts through the API, enabling customers of the partner platform to receive a physical payment card they can use at POS terminals, ATMs, and online merchants across Nigeria and globally where the card scheme is accepted. Physical card issuance involves card personalization (embossing customer name and card details), printing, and delivery to customer addresses, all manageable through API calls that initiate the card production and fulfillment workflow. Bank account creation through Allawee enables partner platforms to create functional Nigerian bank accounts for their customers, complete with a NUBAN (Nigerian Uniform Bank Account Number) that is compatible with all Nigerian interbank transfer systems including NIP (NIBSS Instant Payment). Customer accounts created through Allawee can receive inbound transfers from any Nigerian bank and initiate outbound transfers to any Nigerian bank account, providing full interbank connectivity through a single BaaS API integration. Spend controls in the Allawee Card API allow partner platforms to set per-transaction limits, daily spending limits, merchant category restrictions, and geographic restrictions on issued cards. A Nigerian fintech issuing employee expense cards can configure spending controls that prevent cards from being used at non-approved merchant categories. An agricultural platform issuing input finance cards can restrict spending to agricultural input supplier merchant categories, ensuring that financed funds are used for their intended purpose. Credit data decisioning from Allawee leverages transaction history and behavioral patterns on the platform to generate credit scores and lending signals that partner platforms can use for automated loan underwriting decisions. For Nigerian lending platforms that issue cards to their borrowers and want to build repayment history and credit profile data from card usage patterns, Allawee's credit decisioning API provides structured credit signals from the same ecosystem where the lending relationship operates. Tokenization support in the Allawee platform enables issued cards to be added to digital wallets (Apple Pay, Google Pay) by card holders, extending card usability to contactless mobile payments in addition to physical card and online payments. As contactless payment adoption grows among Nigerian consumers particularly in Lagos and other major cities, tokenization support adds a distribution channel for issued cards that increases their day-to-day utility. Dispute management through the Allawee API provides structured workflows for handling card transaction disputes — unauthorized transactions, merchant disputes, technical failures — that partner platforms can initiate programmatically when customers report problems. Automated dispute initiation reduces the manual operational burden of handling customer complaints about card transactions and provides systematic tracking of dispute status and resolution. The CBN regulatory compliance infrastructure behind Allawee means that partner platforms are leveraging a regulated entity's banking and card scheme relationships rather than needing to independently establish CBN licensing, Mastercard or Verve principal membership, and the capital requirements those entail. This significantly lowers the barrier for Nigerian fintechs to add card and banking features to their products, compressing the typical 12-24 month timeline for independent licensing into an API integration that can be completed in days or weeks.
