Duplo

Duplo

Duplo is an API-first financial operating system for African businesses, providing a unified platform for B2B payments, expense management, virtual accounts, FX transfers, and NRS-compliant e-invoicing. Headquartered in Victoria Island, Lagos, Duplo is CBN PSSP-licensed, PCI DSS certified, ISO 27001 and 22301 certified, and NDPR-compliant. In early 2026, Duplo became one of the first Nigerian companies to secure dual NRS (Nigerian Revenue Service) licences for e-invoicing — a critical milestone as Nigeria moves toward mandatory digital invoicing for tax compliance. What the API Does The Duplo API enables businesses to: issue and manage virtual bank accounts; initiate bulk payments to up to 500 recipients simultaneously; process local and international card payments; perform FX conversions in 80+ currencies across 160+ countries; automate expense approval workflows with budget controls; perform auto-reconciliation of transactions; and generate NRS-compliant e-invoices. The platform is designed as both a business tool and an embeddable API layer for fintechs and platforms. How Developers Use It Developers access documentation at developers.tryduplo.com. Authentication uses API keys with clear environment prefixes: dp_test_ for test mode, dp_live_ for live mode. The API is REST-based with JSON payloads over HTTPS. All API calls must be made over HTTPS. Developers must complete compliance requirements before being granted live mode access. A sandbox environment is available for full testing. Pricing Local card transactions: 1.5% capped at approximately ₦1,200–₦1,300. International card transactions: 3.8%–4.0%. Custom volume tiers available for high-volume international processing. Contact Duplo for enterprise pricing. Authentication API keys are managed via the Duplo Dashboard. Test mode uses dp_test_ prefixed keys; live mode uses dp_live_ prefixed keys. Never share live keys publicly. Compliance CBN PSSP-licensed, PCI DSS, ISO 27001, ISO 22301, NDPR-compliant, and NRS dual-licensed for e-invoicing. Duplo is also expanding into South Africa via a partnership with Ozow for instant EFT payments. Challenges and Gotchas (1) Live mode requires completing compliance requirements — not instant. (2) Rate limits not publicly documented. (3) The NRS e-invoicing feature is relatively new and developers should check docs for current implementation status. (4) Duplo is B2B focused — not designed for high-volume consumer checkout flows. (5) International card fees (3.8–4%) are higher than local card fees. Company Background Duplo was founded in Nigeria by Yele Oyekola and Damola Ajao and is backed by prominent African and global VCs. The company is focused on solving the complexity of B2B financial operations in Africa, where businesses often manage payments through manual bank transfers, spreadsheets, and fragmented tools. Duplo consolidates this into a single API-first platform. FAQs Q: Does Duplo support bulk payments? A: Yes. Duplo supports bulk payments to up to 500 recipients in a single API call. Q: What is the fee for local card payments? A: 1.5% capped at approximately ₦1,200–₦1,300 per transaction. Q: Is there a sandbox? A: Yes. Test mode is available using dp_test_ API keys from your dashboard. Q: Does Duplo support e-invoicing for Nigerian tax compliance? A: Yes. Duplo holds NRS dual licences for NRS-compliant e-invoicing — one of the first Nigerian companies to do so. Q: Can Duplo handle international payments? A: Yes. Duplo supports 80+ currencies across 160+ countries with international card acceptance at 3.8–4.0%. Duplo's NRS-compliant e-invoicing capability supports Nigerian businesses' obligations under the Federal Inland Revenue Service's e-invoicing requirements, allowing platforms to generate and submit compliant electronic invoices as part of the B2B payment workflow rather than as a separate process.

Miden Banking as a Service API

Miden Banking as a Service API

Miden Banking as a Service API is a sub-Saharan African fintech infrastructure platform that provides card issuance, corporate expense management, virtual accounts, wallet-as-a-service, and multi-country payout capabilities to financial institutions, fintechs, enterprises, and technology companies building embedded payment and financial products across Africa. Miden focuses on the corporate and enterprise financial product space, with particular strength in expense management, corporate card programs, and cross-border payment disbursement. Corporate card issuance is a key Miden capability, enabling partner organizations to issue company expense cards to employees with programmatic spend controls, real-time transaction visibility, and expense categorization. Miden's corporate card infrastructure supports building employee expense management tools where finance teams can see every card transaction in real time, configure per-employee or per-category spending limits, and reconcile expenses automatically without waiting for end-of-month manual reconciliation. For Nigerian companies managing employee expenses across multiple locations and departments, programmatic corporate card management replaces unwieldy petty cash and reimbursement processes. Virtual card issuance through Miden enables platforms to create virtual cards for specific use cases: vendor payment cards with merchant restrictions, single-use purchase cards for procurement, corporate virtual cards for online business expenses, and customer-facing virtual cards for fintech products. Virtual cards are created instantly through the API without physical card production timelines, making them suitable for immediate digital payment needs. NGN and USD accounts provide multi-currency financial infrastructure for Miden partner platforms. Naira accounts enable Nigerian interbank transfers and local payment operations. USD accounts allow platforms to hold dollar balances, make USD-denominated payments, and provide foreign currency account functionality to their customers. The combination of naira and dollar accounts in a single integration supports the multi-currency operational needs of Nigerian businesses engaged in both local and international commerce. Bill payments integration through Miden enables partner platforms to offer airtime top-up, utility bill payment (AEDC, EKEDC, IKEDC, BEDC), cable TV subscriptions (DSTV, GOtv, Startimes), internet data subscriptions, and other Nigerian bill payment categories to their customers. Embedding bill payments into a fintech or banking product increases platform stickiness — customers who pay all their bills through the same app they use for banking are less likely to churn to competing products. Bulk payout operations through Miden enable mass disbursement to bank accounts and mobile money wallets across multiple African countries. For Nigerian logistics companies, gig economy platforms, agricultural aggregators, and marketplace operators that need to pay large numbers of individuals across Nigeria and neighboring markets, Miden's bulk payout API provides the disbursement infrastructure to process hundreds or thousands of individual payouts efficiently in a single operation. Wallet as a Service capabilities allow partner platforms to create digital wallets for their customers — stored value accounts that can receive deposits, make payments, and earn rewards — without the complexity of building wallet infrastructure independently. For Nigerian platforms wanting to add a loyalty or savings wallet feature to their product suite, Miden's Wallet as a Service provides the backend for wallet account management, balance tracking, and transaction processing. Mobile money payout support extends Miden's disbursement coverage to mobile money wallet recipients in markets where mobile money is the primary financial access tool — particularly relevant for cross-border payouts to recipients in Ghana (MTN Mobile Money, Vodafone Cash), Kenya (M-Pesa), and other African markets where mobile money is more prevalent than bank accounts. This multi-rail payout coverage enables Nigerian platforms reaching pan-African beneficiary populations to make payouts regardless of whether recipients have bank accounts.
