11 Best APIs for Bank Transfer Checkout in Nigeria

SeerBit is a Nigerian payment gateway and pan-African payment infrastructure provider founded in 2019 by Omoniyi Kolade and Emmanuel Imam. SeerBit holds a CBN Payment Solution Service Provider (PSSP) license, is PCI-DSS certified, and has expanded beyond Nigeria to provide local payment acquiring in over 10 African markets including Ghana, Kenya, South Africa, Tanzania, Uganda, Côte d'Ivoire, Cameroon, Senegal, and others. This multi-country capability makes SeerBit unique among Nigerian payment gateways — developers can use a single SeerBit account and integration to accept local payment methods across anglophone and francophone Africa. The SeerBit API is RESTful with JSON payloads. Authentication uses two separate keys: a Public Key (used client-side to initialize the checkout widget in the browser) and a Secret Key (used server-side for all backend API calls including transaction verification, transfers, and refunds). Keys are obtained from the SeerBit merchant dashboard. Standard payments flow follows the initialize-then-verify pattern common in Nigerian gateways. SeerBit supports a comprehensive set of payment channels. For Nigeria: card payments (Visa, Mastercard, Verve) with 3D Secure 2.0, bank transfer checkout (virtual account assignment), USSD, direct debit, and cash collections via agents. For other African countries: mobile money (MTN Mobile Money, Orange Money, Airtel Money), local card networks, and bank transfers where available. This unified multi-channel API significantly reduces integration complexity for African-facing platforms. On pricing, SeerBit charges 1.5% per local Nigerian transaction capped at ₦2,000, with no setup fee. International card transactions are charged at 3.8% — slightly lower than Paystack (3.9%) and Monnify (4%), which can represent meaningful savings at scale. There is no monthly platform fee. Settlement occurs within 24 hours for Nigerian transactions. Rates for other African countries vary by market and are available from SeerBit's pricing page. SeerBit also offers SeerBit Alpha — a Banking-as-a-Service (BaaS) offering that enables fintechs and platforms to launch embedded financial products including wallets, virtual cards, lending, and savings features without building payment infrastructure from scratch. Alpha is targeted at Nigerian startups that want to go to market quickly with financial products. The Direct Debit feature allows businesses to set up debit mandates on customer bank accounts for recurring billing. Customers authorize the mandate once, and the platform can automatically debit them on a schedule. This is particularly useful for subscription-based products, loan repayment collection, and Nigerian SaaS companies billing in recurring cycles. The sandbox environment mirrors production. SeerBit provides test card numbers, simulated bank transfer flows, and test USSD responses for all supported channels. The sandbox is accessible immediately after creating a developer account. From a compliance standpoint, SeerBit is regulated by the CBN under the PSSP license category, which covers payment gateway, payment terminal service, and payment solution service operations. SeerBit is also PCI-DSS certified, ensuring all card data is handled and stored securely. The company is backed by Adaverse and other African-focused venture funds. Known challenges: SeerBit's documentation is functional but less polished than Paystack's. Community support resources (Stack Overflow answers, third-party tutorials) are more limited. Some advanced features like marketplace split payments are not yet available. For West African mobile money corridors in ECOWAS countries, SeerBit's coverage continues to expand. Frequently Asked Questions: How does SeerBit's international rate compare to competitors? SeerBit charges 3.8% for international cards compared to Paystack's 3.9% + ₦100 and Monnify's 4%. For high-value international transactions, SeerBit can be more cost-effective. Can I accept mobile money from Ghana and East Africa with SeerBit? Yes — SeerBit supports MTN MoMo, Airtel Money, and Orange Money in multiple African markets through the same API integration. Does SeerBit support Nigeria-to-Africa cross-border payouts? SeerBit is primarily a collection gateway. For cross-border payouts originating from Nigeria, complementary tools are needed.

Kora (formerly Korapay) is a CBN-licensed pan-African payment infrastructure company offering a unified API for payment acceptance, payouts, identity verification, and exchange rates across Nigeria, Ghana, Kenya, and South Africa. The company rebranded from Korapay to Kora to signal its evolution from a single-market payment gateway to a multi-country API platform. Kora serves Nigerian and pan-African fintechs, marketplaces, and enterprises with a developer-first API design. What the API Does The Kora API provides: card payment acceptance (local and international); bank transfer checkout; mobile money payments across Africa; payouts to Nigerian and other African bank accounts; identity verification (BVN, NIN, vNIN, CAC, and multi-country KYC); a real-time exchange rate API; and webhook notifications for all transaction events. The API base URL is api.korapay.com/merchant. How Developers Use It Developers sign up at korahq.com, complete business verification, and obtain API keys from their Kora dashboard. Authentication uses Bearer tokens — the secret key is passed as "Authorization: Bearer {SECRET_KEY}" in request headers. Test mode uses separate test keys; live mode requires dashboard activation. Sandbox testing is available with specific test cards and bank account numbers. The full API reference is at developers.korapay.com and docs.korapay.com (OpenAPI spec available at developers.korapay.com/llms.txt). Pricing Not publicly listed. Per-verification costs for identity services are deducted directly from the Kora account balance. Payment processing fees require contacting Kora directly. Sandbox/test mode is free. Rate Limits Not publicly documented — contact Kora support for limits before high-volume integrations. Compliance CBN-licensed in Nigeria. Multi-country presence with appropriate regulatory relationships in Ghana, Kenya, and South Africa. Encryption and security-grade protocols for all identity verification calls. Challenges and Gotchas (1) Identity service activation is separate from standard payment access — must be enabled in dashboard. (2) No public rate card — pricing requires direct engagement. (3) Rate limits not documented. (4) Two documentation sites exist (developers.korapay.com and docs.korapay.com) — both are maintained but can cause confusion. (5) Recurring billing not currently supported. Company Background Kora was founded in Nigeria and has grown into a multi-country payment infrastructure provider. The company raised a Series A round and is backed by African and global investors. The rebrand from Korapay to Kora reflected the platform's expansion beyond Nigeria to serve pan-African payment flows. FAQs Q: Is Kora the same as Korapay? A: Yes. Korapay rebranded to Kora to reflect its multi-country expansion. Q: Does Kora support mobile money across Africa? A: Yes. Mobile money payments are supported across multiple African markets. Q: Is there a sandbox? A: Yes. Use test keys and the provided test card/bank account numbers to simulate payments. Q: Does Kora have an exchange rate API? A: Yes. A real-time exchange rate API is included in the Kora API suite.

Monnify is a Nigerian payment gateway and payment infrastructure provider operated by Moniepoint Inc, a CBN-licensed payment solutions company and one of Nigeria's largest agent banking networks. Originally launched as a standalone product by TeamApt, Monnify was rebranded under the Moniepoint brand as the company expanded. Monnify provides Nigerian businesses with APIs for accepting payments via local debit cards, bank transfers, USSD, and direct debit, as well as disbursing funds to bank accounts across all Nigerian banks. The Monnify API is RESTful and uses JSON for all request and response payloads. Developers can authenticate using Basic Auth — by encoding the API key and secret key as a base64 string — or by exchanging credentials for an OAuth Bearer Token via the /auth/login endpoint. Most implementations prefer Bearer Token authentication for production use, obtaining a token at server startup and refreshing as needed. The Monnify dashboard is available at app.monnify.com and provides API credentials, transaction history, settlement reports, and webhook configuration. Payment collection works by initializing a transaction with a unique reference and an amount, then displaying the payment modal to the customer. The Monnify SDK handles the checkout experience, allowing customers to choose between card, bank transfer, USSD, or direct debit. For bank transfers, Monnify generates a reserved virtual account number for the customer — they transfer any amount to that account and the payment is automatically matched and settled to the merchant. This is particularly powerful for recurring or subscription-like payment flows. In terms of pricing, Monnify charges 1.5% per transaction for local card payments, USSD payments, and bank transfers, with a cap of ₦2,000 per transaction. An alternative flat fee of ₦500 may apply for certain bank transfer transactions. International card payments attract a 4% fee. Cash collection is also charged at 4%. There are no setup fees and no monthly platform fees. Payouts (disbursements to Nigerian bank accounts) are charged at flat rates: ₦10 for transfers below ₦10,000, ₦20 for transfers between ₦10,000 and ₦49,999, and ₦40 for transfers of ₦50,000 and above. All fees are exclusive of VAT. A key differentiator for Monnify is its settlement speed. Transactions are settled to merchants same-day by 10pm, and businesses can trigger up to 3 on-demand express settlements per day outside the standard settlement window. This is important for Nigerian e-commerce and service businesses that need immediate access to collected revenue. The Monnify sandbox environment is a full replica of the production environment. Developers can create a free sandbox account at developers.monnify.com without any business registration documents. The sandbox provides test card numbers, simulated bank transfer flows, and test USSD responses. Moving from sandbox to live requires completing the standard CBN KYC process, including submitting CAC documents, director BVN, and business bank account details. Rate limits for the Monnify API are not publicly published. However, for high-volume integration partners, Monnify support can provide guidance on expected throughput limits. The Webhook system sends real-time notifications for transaction completion, refunds, and disbursements — developers must validate the webhook hash to confirm the event originated from Monnify, and must respond with HTTP 200 within a defined timeout. From a compliance standpoint, Monnify is CBN-licensed and operates under the same regulatory framework as all Nigerian payment service providers. Moniepoint Inc holds a Payment Service Bank license and a Switching and Processing license from the CBN. Monnify is also PCI-DSS certified, which is required for handling card payment data in Nigeria. Merchants are not required to be PCI-DSS certified themselves, as card data is processed on Monnify servers rather than the merchant's infrastructure. The BVN verification endpoint available through Monnify allows developers to verify a customer's Bank Verification Number — returned with name, date of birth, and phone number — which is a CBN requirement for KYC compliance in lending and financial services. Common challenges Nigerian developers face with Monnify include webhook delivery delays during peak traffic (Black Friday, end-of-month), and the need to handle cases where bank transfer payments arrive outside the transaction expiry window. Developers should set generous expiry windows for bank transfer transactions, and use the transaction status query endpoint to confirm payment before fulfilling orders, rather than relying solely on webhook delivery. Moniepoint Inc, the parent company, is headquartered in Lagos, Nigeria and has expanded operations across several African markets. It was voted the fastest-growing company in Africa by the Financial Times in 2023 and has raised over $100 million in funding. Notable investors include QED Investors, Lightrock, and Google. The Monnify gateway is used by thousands of Nigerian businesses including e-commerce platforms, SaaS companies, and lending products. Frequently Asked Questions: Can I use Monnify without CAC registration? You can test the API freely on the sandbox with just an email. However, to go live and receive real settlements, full CBN KYC including CAC registration is required. Does Monnify support NGN only? Yes, Monnify primarily settles in Nigerian Naira (NGN). International card transactions are charged at 4% but are settled in NGN after currency conversion. Does Monnify have a no-code payment link? Yes, Monnify supports payment links and invoice generation from the dashboard — no coding required. What happens if my webhook fails? Monnify retries failed webhook deliveries. However, developers should use the transaction status API (/api/v1/merchant/transactions/query) as a fallback to confirm payment independently.

Squad is a Nigerian payment gateway and developer-first payment infrastructure platform operated by HabariPay Limited, the fintech subsidiary of Guaranty Trust Holding Company (GTCO) — the parent company of Guaranty Trust Bank, one of Nigeria's Tier 1 commercial banks. This institutional backing gives Squad a unique position in the Nigerian fintech ecosystem: it combines the regulatory standing of a CBN-licensed commercial bank group with a modern API-first developer experience. Squad is available at squadco.com and provides documentation at docs.squadco.com. The Squad API is RESTful with JSON payloads. Authentication is via Bearer Token — developers obtain a secret key from the Squad dashboard and pass it in every request as Authorization: Bearer sk_test_xxxx (sandbox) or Authorization: Bearer sk_live_xxxx (production). All amounts are passed in Naira (NGN), unlike some Nigerian gateways that require amounts in Kobo. Squad's payment gateway supports card payments (Verve, Visa, Mastercard), bank transfers, and USSD — the three primary payment channels used by Nigerian consumers. The standard integration follows a three-step flow: initialize a transaction by posting to the Squad initiate endpoint with amount, email, and a unique transaction reference; display the Squad checkout widget to the customer; and verify the transaction on your server after the customer completes payment. Squad provides both a hosted checkout page and an embeddable inline SDK for seamless checkout experiences. One of Squad's most notable differentiators is its fee structure. The payment gateway charges a percentage fee capped at ₦1,500 per transaction — lower than Paystack (₦2,000 cap) and Monnify (₦2,000 cap). For virtual account collections, Squad charges a percentage capped at ₦1,000, which is again among the lowest caps in the Nigerian market for bank transfer collections. Payment links (used for social commerce and invoicing) are charged at 1% for local transactions and 3.5% for international transactions. This pricing advantage makes Squad particularly attractive for businesses processing high-value transactions, where the cap limits the absolute cost per transaction regardless of size. Squad's Virtual Accounts feature assigns a dedicated bank account number to each customer for use in collections. Businesses can create virtual accounts for individual customers — when a customer transfers any amount to their dedicated account, the Squad webhook fires and the balance is credited in real time. This is widely used by Nigerian savings apps, investment platforms, and bill payment services where customers top up wallets via bank transfer. The Subscription API allows platforms to create recurring billing products. When a customer first pays via Squad, the platform receives a unique charge token tied to that customer's card. Future charges can be triggered by passing this token without requiring the customer to re-enter card details — enabling automatic monthly subscriptions, usage-based billing, and installment plans for Nigerian consumers. Squad also provides a Payouts API for disbursing funds to any Nigerian bank account. Developers submit a destination bank code, account number, and amount, and Squad executes the transfer. Payout pricing is competitive and the API supports both single and bulk transfers. The BVN verification endpoint available through Squad allows platforms to look up a Bank Verification Number and return the associated name and basic identity information. This is commonly used by Nigerian lending products and fintech apps to confirm user identity as part of CBN-required KYC processes. The Squad sandbox environment provides full test mode access. Developers can test all features — gateway payments, virtual accounts, subscriptions, payouts, and BVN verification — using test credentials without processing real transactions. Moving to live requires completing Squad's business onboarding, including submitting CAC registration, director BVN, and a valid business bank account. From a compliance perspective, HabariPay Limited is a CBN-licensed Payment Service Provider operating under the regulatory oversight of the Central Bank of Nigeria. GTCO's banking license adds an additional layer of institutional compliance. Squad is also PCI-DSS certified, ensuring that card payment data is processed and stored to the highest security standards. Squad runs an annual Hackathon for Nigerian students and early-career developers — Squad by GTBank Hackathon — providing cash prizes and API credits to winners. This investment in the developer community has built significant goodwill among Nigeria's emerging developer ecosystem. Known challenges: Squad's documentation, while functional, is less comprehensive than Paystack's. Some advanced integration patterns (split payments, multi-vendor marketplace flows) are not as fully documented. The Squad developer community is smaller than Paystack's, which can make troubleshooting harder for niche use cases. Frequently Asked Questions: Is Squad backed by GTBank? Yes — Squad is operated by HabariPay Limited, which is a subsidiary of Guaranty Trust Holding Company (GTCO), the same holding company that owns GTBank. What is the fee cap advantage? Squad's gateway fee is capped at ₦1,500 versus ₦2,000 for Paystack and Monnify — meaning on large transactions, you save ₦500 per collection. Does Squad support dollar transactions? Squad supports international card payments (Visa/Mastercard). Settlement is in NGN. Can I test Squad without registering a business? Yes — create a free developer account and use the sandbox with test credentials before submitting any business documents.

Payaza Africa Limited is a pan-African payment gateway and financial services platform headquartered in Lagos, Nigeria, with operating licenses in 16+ countries including Nigeria, Ghana, Kenya, Tanzania, Liberia, Zambia, Rwanda, Uganda, Benin Republic, Côte d'Ivoire, Zimbabwe, Namibia, the DRC, Bahrain, the United Kingdom, the United States, Canada, and the UAE. This extensive multi-country licensing makes Payaza one of the most geographically diverse African payment platforms available to developers — a single Payaza API integration can power both local Nigerian payments and international collections from the UK, Canada, and the UAE. Payaza's developer documentation is available at docs.payaza.africa, with integration support at payaza.africa/integration-support. The API is RESTful with JSON payloads. Authentication uses a Bearer Token (Secret Key from the Payaza merchant dashboard). The API design follows standard patterns familiar to developers who have used Paystack or Flutterwave. Payaza supports card payments (Visa, Mastercard, Verve), bank transfer checkout, and mobile money across its supported markets. In Nigeria specifically, the gateway supports local debit card transactions, bank transfer collections, and outbound payouts to Nigerian bank accounts. In West Africa, mobile money is supported via integration with MTN Mobile Money, Orange Money, and other providers. For UK and international merchants, Payaza's local acquiring licenses enable card acceptance in British pounds and other major currencies. Multi-currency support is a primary differentiator. Merchants can configure Payaza to accept payments in NGN, GBP, USD, CAD, EUR, KES, GHS, and other currencies depending on their licensed market. This is particularly valuable for Nigerian diaspora businesses, e-commerce platforms with international customers, and SaaS companies billing customers globally. Payaza offers fast local and international payouts. For Nigerian businesses, payouts to local bank accounts are processed within standard Nigerian interbank timelines. For international payouts, Payaza's licenses in the UK, US, and Canada enable direct disbursement to foreign bank accounts without the complexity of SWIFT correspondent banking. The platform is built with security and compliance at its core. Payaza holds investment-grade security certifications and is PCI-DSS compliant. The platform has been described as offering "the most enjoyable payment experience" by Nigerian SME users, reflecting a focus on clean UI, fast onboarding, and responsive merchant support. Payaza has a particular strength in the creator economy and SME segment. Nigerian freelancers, digital product sellers, and content creators use Payaza to collect international card payments from overseas clients and receive settlement in their Nigerian accounts. The payment link feature requires no coding — making it accessible to non-technical merchants. Exact pricing is not publicly published on the Payaza website. Transaction fees are approximately 1.4–1.5% for local Nigerian transactions plus applicable flat fees, with international rates higher. Merchants are advised to contact Payaza directly for current rates based on their expected transaction volume and geography. The Payaza sandbox environment is available for testing. Moving from sandbox to live requires completing KYC onboarding including CAC registration, director BVN and government ID, and a business bank account. For international markets, Payaza may request additional compliance documentation depending on the country. From a compliance standpoint, Payaza Africa Limited is licensed by the CBN in Nigeria and has equivalent regulatory approvals in each of its 16+ operating jurisdictions. The breadth of licenses is a significant competitive advantage that took years to accumulate and represents a high barrier to entry for competitors. Frequently Asked Questions: How many countries does Payaza support? Payaza is licensed in 16+ countries as of 2026, including Nigeria, Ghana, Kenya, UK, US, Canada, and UAE. Additional markets are being added. Does Payaza support USD and GBP collection? Yes — Payaza can collect USD and GBP directly using its US and UK licenses, eliminating the need for separate payment processors in those markets. What is the onboarding time for Payaza? Nigerian business onboarding typically takes 2–5 business days depending on KYC document completeness. Is Payaza publicly traded? No — Payaza Africa Limited is a private company.

Nomba is a Nigerian payment infrastructure company and CBN-licensed Payment Service Provider. Formerly known as Kudi, Nomba pivoted from a consumer-facing payment agent app to a comprehensive B2B payments infrastructure platform serving Nigerian businesses with APIs for checkout, virtual accounts, transfers, and POS terminal management. Nomba is backed by Stripe and significant venture capital, and powers millions of transactions daily across Nigeria's merchant and agent banking ecosystem. The Nomba API is RESTful with JSON payloads and uses OAuth2 for authentication. Developers can authenticate via two methods: the Client Credentials grant (server-to-server, for backend integrations) or the PKCE (Proof Key for Code Exchange) grant (for mobile and single-page app integrations where the secret cannot be safely stored). In both cases, an access_token is generated and passed in every API request as an Authorization: Bearer <token> header. API keys are retrieved from the Nomba business dashboard under Settings > API Keys. The Checkout API is the core product for accepting payments. Developers initialize a checkout session server-side by sending a POST request with the amount, currency (NGN), and a unique transaction reference. Nomba returns a hosted checkout URL that the developer redirects the customer to. The checkout supports card payments (Verve, Visa, Mastercard), USSD, and bank transfers. Nomba handles the entire payment experience on its hosted page — merchants do not need to build a custom checkout interface. For fund collection from specific customers, Nomba supports Virtual Accounts — unique bank account numbers assigned to individual customers or transactions. When a customer transfers any amount to their virtual account number, Nomba fires a webhook confirming the payment. This is ideal for Nigerian wallet top-ups, marketplace deposits, and savings apps where customers fund their balance via bank transfer. The Transfers API enables instant outbound bank transfers to any Nigerian bank account. Developers can send disbursements by specifying the destination bank code, account number, amount, and a unique transfer reference. Nomba executes the transfer via the Nigerian banking system. This is commonly used for payroll, agent commissions, loan disbursements, and refunds. Nomba also supports tokenized card flows — when a customer first pays with a card, Nomba can return a card authorization token that the merchant stores and uses for future charges without requiring the customer to re-enter card details. This enables installment plans, subscription-like products, and one-click repeat payments. For merchants with physical locations, Nomba provides a Terminals API that enables developers to build custom POS applications. Integrators can send payment requests to Nomba POS terminals, receive confirmation webhooks, and build merchant dashboards that pull transaction data from the terminal network. This is a unique capability that distinguishes Nomba from pure online payment gateways like Paystack or Flutterwave. Webhooks are available for all major events: payment success, payment failure, transfer completion, and virtual account credit. Developers must validate the webhook signature before processing events to ensure authenticity. The Nomba sandbox environment is available for all API products. Developers can test checkout, virtual accounts, and transfers without processing real money. Moving to live requires completing Nomba's business onboarding and CBN KYC verification. From a compliance standpoint, Nomba holds a CBN Payment Service Bank license and is licensed as a Payment Service Provider. All transactions are processed within the CBN regulatory framework. The platform is used by hundreds of thousands of Nigerian merchants, particularly small businesses, market traders, and logistics companies that use Nomba POS terminals. Frequently Asked Questions: How is Nomba different from Paystack? Paystack is primarily an online payment gateway. Nomba additionally offers POS terminal integration, agent banking infrastructure, and the Global Payout API for cross-border disbursements — making it more comprehensive for merchants with physical and digital presence. Is Nomba pricing public? Nomba does not publish exact API pricing. Contact the Nomba team for transaction fee schedules based on your volume and use case. Can I use Nomba for cross-border payments? The main Nomba API is for domestic Nigerian payments. For cross-border disbursements, use the separate Nomba Global Payout API which was launched in March 2026.
