Nium is a Singapore-headquartered global payments infrastructure company that provides businesses with a unified API to send payments to 190+ countries, collect payments in 35+ markets, and issue physical and virtual cards in 30+ countries. Nium is a licensed financial institution in multiple jurisdictions including the US, UK, EU, Singapore, and Australia, and serves financial institutions, fintech companies, banks, and enterprises that need to build or scale cross-border payment capabilities. The Nium API is RESTful with JSON payloads. Documentation is at docs.nium.com. Authentication uses API Key credentials passed in request headers (client-id and x-api-key). Nium operates a payout platform (mpdocs.nium.com) that provides the most detailed technical integration guidance for developers building payment products. For payouts, Nium supports 190+ destination countries with 65 of those available in real-time. The supported corridors span the Americas, Europe, Middle East, Africa, Oceania, and Asia-Pacific. Nigeria falls within Nium's Africa coverage — however, the exact payment methods, corridors, and processing times for Nigeria should be confirmed via the Nium Playbook at playbook.nium.com before integration. Payout fees are calculated in real-time at transaction execution and are corridor-specific. For collections, Nium supports receiving payments in 35+ markets using local payment methods. This covers bank transfers, card payments, and local e-wallets depending on the market. Nigeria-specific collection support should be confirmed separately. Nium also offers card issuance APIs in 30+ countries — enabling fintechs and banks to issue virtual and physical Visa/Mastercard cards to their customers. Cards can be issued in multiple currencies and managed programmatically (freeze, unfreeze, set spending limits, retrieve transactions). Webhooks are available for all major events: payout processing, payout completion, payout failure, and card transaction alerts. Developers can configure webhook endpoints during Nium account setup. The sandbox environment provides full testing capability for all Nium products. Moving to live requires completing Nium's enterprise onboarding, including business verification and compliance review by a Nium account manager. From a compliance standpoint, Nium is regulated in multiple jurisdictions globally. The company holds money transmitter licenses in all US states, FCA authorization in the UK, Payments Institution license in the EU, and MAS Major Payment Institution license in Singapore. For transactions to/from Nigeria, Nium routes through local correspondent partners that are CBN-licensed. Nium raised $200 million at a $2.1 billion valuation in 2022, making it one of the most well-capitalized global payment infrastructure companies. Clients include large banks, digital banks, travel companies, and enterprise platforms globally. Frequently Asked Questions: Is Nigeria a supported payout destination on Nium?
